When people are immunocompromised, exposure to what might ordinarily be a harmless fungus can cause significant health problems.

Researchers in the laboratory of Maurizio del Poeta, Distinguished Professor in the Department of Microbiology and Immunology at the Renaissance School of Medicine at Stony Brook University, have been looking to create new treatments and develop vaccines against these fungi.

Working with a team of scientists at Stony Brook, research scientist Nivea Pereira de Sa, who joined del Poeta’s lab in 2018 as a postdoctoral researcher, recently published research in the journal mBio about potential anti-fungal drugs that target a key enzyme in the fungus Aspergillus fumigatus. 

Without the enzyme, the fungus can’t cause disease and the host defenses have time to eliminate it even if the host is immunodeficient.

Working with Michael Airola, Assistant Professor in the Department of Biochemistry and Cell Biology at SBU, Pereira de Sa started out by trying to find the structure of sterylglucosidase, an enzyme that is a molecular key for the fungus during infection and that aids in its ability to adapt to environmental changes such as low oxygen levels and changes in pH.

Pereira de Sa learned how to do x-ray crystallography from Airola, a process that reveals the structure of compounds.

In an email, Airola described Pereira de Sa as an “expert” in the technique.

Airola called the research “one of the most exciting projects” he’s worked on and hopes the group can translate the results into the clinic. A talented biochemist, Pereira de Sa is also an “expert in so many different scientific areas,” Airola wrote, which he described as “rare.”

Pereira de Sa also determined the structure of the same enzyme for Cryptococcus, another invasive and potentially harmful fungus. The enzymes in both fungi have a high degree of similarity.

Pereira de Sa expressed satisfaction at the application of such work. “Every time I get a crystal structure, it’s so amazing,” she said. “I love doing that.”

Pereira de Sa started screening potential compounds to inhibit sterylglucosidase in Aspergillus,

Del Poeta’s lab coordinated the design and testing of these inhibitors with Iwao Ojima, Distinguished Professor in the Department of Chemistry and Director of the Institute of Chemical Biology and Drug Discovery at Stony Brook.

Refining potential drugs

Ojima’s group is synthesizing derivatives of the hits Pereira de Sa found and she will start tests outside a living organism, or in vitro, soon.

Ojima has synthesized several compounds using computer-assisted drug design. He is currently developing several inhibitors that scored high on his computational molecular docking analysis and will synthesize two to three dozen potential small molecules.

Ojima, who partnered with Pereira de Sa in this study, “greatly appreciates her and her seminal contributions to this project,” he wrote in an email. She made critical contributions to the study that ensured its success and Stony Brook is “very fortunate to have her as a leader in this project.”

Ojima plans to identify highly potent inhibitors individually for Aspergillus and Cryptococcus separately, and then will try to find and develop broad spectrum inhibitors based on those compounds.

The need for a treatment has increased dramatically as the number of immunocompromised patients has increased.

Invasive aspergillosis can have mortality rates above 90 percent. The World Health Organization last October released its first ever list of health threatening fungi, which includes Aspergillus.

Pereira de Sa suggested two possible uses for this inhibitor. It could work as a treatment, knocking down the virulence of the fungus or it could contribute to the development of a vaccine.

In strains with a mutated enzyme, a mouse model has full protection against infection.

Getting a vaccine approved through the Food and Drug Administration for immunocompromised individuals might be challenging, she said. Several studies would be needed to confirm its safety.

Del Poeta added that the vaccine his lab has developed is effective alone when heat killed, reducing the threat a live virus with a defective enzyme might pose to an immunocompromised patient. Del Poeta has been developing a vaccine for cryptococcus and aspergillus and is testing it for other fungal infections as well.

‘A beautiful cause’

Del Poeta described Pereira de Sa as a key contributor to his lab, who is methodical, systematic and hard working.

The program she is developing will take years to go to clinical trials, he added.

Del Poeta met Pereira de Sa in 2017, when he visited Brazil and spoke with her mentor, Daniel de Assis Santos, who gave her an enthusiastic reference.

After meeting with her for only five minutes, del Poeta offered her a job.

“I will never forget her face: surprised, joyful, excited and she could not hold back some tears,” del Poeta described.

Del Poeta is thrilled with his choice, as she has gone above and beyond his expectations.

Born and raised in Belo Horizonte, Brazil, Pereira de Sa lives in East Setauket with her husband Rodrigo Carvalho da Silva, who is an airplane mechanic.

She enjoys Long Island, particularly during the summer, when she goes hiking, visits parks, kayaks and goes paddle boarding.

Pereira de Sa is encouraged by the progress in her work and is hoping her research contributes to future treatments.

“We are developing tools to help people,” she said. “It’s a beautiful cause I’m fighting for.”

She said the mortality rate from these fungal infections is “very high,” especially because a fungus like Aspergillus is ubiquitous.

“The fungus is present everywhere,” she said. “We are inhaling the spores of it every day.”

The invasive fungal disease starts in the lungs and spreads to the rest of the body, including in the brain, which can cause seizures.

Pereira de Sa recognizes the urgency of developing an effective treatment.

“We need some solutions and we need it now,” she said. “We are not prepared to fight fungal infections” on a large scale.

The Stony Brook baseball team (5-9, 0-0 CAA) capped off their 5-0 week this afternoon after finishing off the series sweep against Lafayette College (3-12, 0-0 Patriot League) by defeating the Leopards 9-3 at Joe Nathan Field on March 12.

For the third time in the last five games, the Seawolves fell behind early but did not waver. After the team from Pennsylvania scored a run in the top half of the first inning, Stony Brook responded right back with a run of their own. Senior Shane Paradine tallied the first of his two hits in the afternoon and drove in sophomore Matt Miceli to tie the game.

Then, following another run by the Leopard offense in the second inning, the Seawolves would go on to score seven unanswered runs to take a 8-2 lead in the fifth and ultimately the 9-3 victory.

The Seawolves sent out graduate Kyle Johnson to make his second start of the season and sixth start of the year this afternoon. 

After the right-hander stranded a runner on second base with no outs by retiring the next three batters, freshman Eddie Smink came in to make his fourth appearance of the year. Smink, a native of West Chester, Pa., produced his strongest outing of the season after allowing just one run over a career-high 5.0 innings out of the pen. Also, the right-hander allowed one walk and faced two batters over the minimum as he battled only 17 batters over the 5.0 innings.

In the bottom of the fourth, Stony Brook tied the game at 2–2 after junior Matt Brown-Eiring advanced Paradine to third on a hit-and-run action play, and then scored after Brown-Eiring drew a pick-off.

The Stony Brook offense would finally erupt in the fifth inning by tallying six runs in the frame. Leading the charge was the sophomore class as Anthony Gentile started the inning by drawing a walk, followed by fellow sophomore Chris Leone reaching on an error, and second year player Matt Miceli loading the bases on a bunt base-hit. Freshman Matthew Wright made his first appearance in the two-spot for the Stony Brook offense this season and drove in Gentile by reaching on a walk.

The Seawolves did not have to wait long on base, as graduate Evan Giordano cleared the bases by launching a double to right center. After the double, Paradine collected a double for himself down the right field line to drive in Giordano. Junior Derek Yalon would cap off the inning by bringing home Paradine on a sacrifice-fly and giving Stony Brook the 7-2 lead in the bottom of the fifth.

Freshman Jerek Hobb made his second appearance of the weekend and struck out two batters in the ninth inning to seal the 9-3 victory for Stony Brook and extend their winning streak to five games.

“I am very proud of our guys, it’s a real credit to them. When you have a start like we had, playing some of the best teams in the country, it’s easy to get off track. But, we regrouped together and I am very proud of the way that they stepped up to the challenge,” said head coach Matt Senk.

The Stony Brook softball team (6-8, 0-1 CAA) fell to Elon University (7-14, 1-0 CAA), 6-2, in its first-ever CAA contest on March 10 at Hunt Softball Park in Elon, N.C.

The Phoenix got off to an early lead, scoring two runs in the first inning courtesy of a two-run home run by Elon’s Claudia Penny. The Seawolves cut their deficit to 2-1 in the top of the third when senior outfielder Shauna Nuss stole home.

STATS: 

Nuss went 2-3 at the plate and recorded the only RBI of the contest. The senior singled to left field to bring home junior outfielder Julianna Sanzone.

Junior infielders Kyra McFarland and Brooke Dye, junior outfielder Alicia Orosco and freshman infielder Naiah Ackerman all recorded a hit in the game.

Sophomore pitcher Maddie Male got the start in the circle, she tossed 2.2 innings before senior Ashton Melaas took over.

Stony Brook would not be able to keep up as the Phoenix would go on to plate four more runs in the bottom of the third off back-to-back hits and ultimately seal the 6-2 victory.

The team heads to Fairfield, C.T. on March 16 to take on Sacred Heart University at 2 p.m. and 4 p.m. The games will be broadcast live on FloSoftball.

NEWS FROM STONY BROOK UNIVERSITY:

With their long necks and formidable bodies, sauropod dinosaurs have captured people’s imaginations since the first relatively complete sauropod fossils were discovered in the United States in the late 1800s. Now an international team led by Stony Brook University paleontologist Andrew J. Moore, PhD, has revealed that a Late Jurassic Chinese sauropod known as Mamenchisaurus sinocanadorum sported a 15-meter-long neck. The new analysis of this dinosaur, published in the Journal of Systematic Palaeontology, provides fresh insights on the evolution of the iconic sauropod body.

For sauropods, the long neck was the anatomical key to achieving large body size. To power such a large body, sauropods had to be efficient at gathering foodstuffs, and that’s what a long neck was built for. A sauropod could plant itself in one spot and hoover up surrounding vegetation, conserving energy while taking in tons of food. Having a long neck probably also allowed enormous sauropods to shed excess body heat by increasing their surface area, much like the ears of elephants. This way of life – long neck-fueled, quadrupedal gigantism – is not one that is available to mammals or any other form of life today. The sauropod lifestyle was exceptionally successful: their lineage appeared early in dinosaur evolutionary history and persisted until the final days of the Mesozoic, when an asteroid wiped out all dinosaurs (except birds).

Mamenchisaurus sinocanadorum was discovered in approximately 162-million-year-old rocks from the Xinjiang Uyghur Autonomous Region of northwest China in 1987 by the China–Canada Dinosaur Project team, for which it was named in 1993. At approximately 15.1 meters, its neck was more than six times longer than the necks of giraffes, the longest-necked animals alive today, and about 10 feet longer than a typical school bus.

The question of which sauropod had the longest neck is not straightforward. Because of their size, the largest sauropods tend to be some of the most poorly known: it’s very hard to bury such a large animal in sediment and thus safeguard it for fossilization.  Some fragmentary fossils suggest that other sauropod lineages independently evolved necks over 10 meters (32.8 feet) in length. However, poor preservation of these specimens and their closest relatives makes estimates of their neck length speculative.

According to Moore, Assistant Professor in the Department of Anatomical Sciences in the Renaissance School of Medicine at Stony Brook University, although Mamenchisaurus sinocanadorum is known only from a handful of bones from the neck and skull, the research team was able to reconstruct its evolutionary relationships and thus make comparisons to the unusually complete skeletons of its closest relatives. This allowed them to conclude that Mamenchisaurus sinocanadorum had a neck approximately 15.1 meters (49.5 feet) long, the longest neck that can be confidently inferred for any known sauropod.

Their research stems from on-going work to comprehensively document the anatomical diversity and evolutionary history of the family Mamenchisauridae, a radiation of particularly long-necked sauropod dinosaurs that roamed East Asia and possibly other parts of the world from the Middle Jurassic to the Early Cretaceous (approximately ­174–114 million years ago).

“All sauropods were big, but jaw-droppingly long necks didn’t evolve just once,” says Moore. “Mamenchisaurids are important because they pushed the limits on how long a neck can be, and were the first lineage of sauropods to do so. With a 15-meter-long neck, it looks like Mamenchisaurus sinocanadorum might be a record-holder — at least until something longer is discovered.”

How sauropods managed to evolve such long necks and hulking bodies without collapsing under their own weight remains something of a biomechanical puzzle. Remarkable specimens like Mamenchisaurus sinocanadorum provide some clues. For example, like their living cousins, birds, most sauropods had air-filled bones, which would have lightened their skeletons by removing heavy marrow and bone tissue.

Using computed-tomography (CT) scanning, Moore and colleagues found that the vertebrae of Mamenchisaurus sinocanadorum were mostly air (about 69–77% of their volume) – comparable to the lightly built skeletons of storks and other birds.

However, such featherweight skeletons would also be more prone to injury. To combat this, Mamenchisaurus sinocanadorum had 4-meter-long rod-like cervical ribs, bony extensions of the vertebrae that created overlapping bundles of rods on either side of the neck. These bundles would have stiffened the neck of Mamenchisaurus sinocanadorum, increasing its stability and making it possible to build such a lightweight neck.

“Biomechanical studies of the mamenchisaurid neck suggest that it was elevated at only a relatively shallow angle above the horizontal (20-30°). However, even at this relatively shallow angle, the extreme length of the neck would still mean that the animal’s head could reach heights of around 7.5 to 10 m above ground level, facilitating feeding on tree foliage,” says co-author Paul Upchurch, PhD, a Professor of Palaeobiology from the University College London.

“Mamenchisaurus sinocanadorum underscores how much we can learn about sauropod evolution even from very incomplete specimens,” adds co-author Ye Yong, director of the Research Center of Jurassic Stratigraphy and Paleontology at the Zigong Dinosaur Museum in China’s Sichuan Province.

The research was funded by numerous organizations including the United States National Science Foundation, The Royal Society of London, and the National Natural Science Foundation of China.

Last summer, the Anthropology Department at Stony Brook University brought 13 students to the south of France to help gather information from a rich archaeological site called the Grotte Mandrin.

The trip with the Field School through SBU Study Abroad enabled the students to work in the field and gather information from a site that has provided a treasure trove of information about Neanderthals and Homo sapiens from 54,000 years ago.

The students found the trip successful, inspirational and, at times, exhausting.

“I did archeology all summer,” said Asa Wong-Gómez, a senior anthropology major at Stony Brook, who spent time in Kenya before joining the team in France. “It was really cool.”

Wong-Gómez recalled the thrill of finding teeth and stones in the dirt. “The first day, everyone’s first find was super exciting,” he said.

The field expedition, which was the first Stony Brook ran at this site, enabled students to forge connections with each other and with the site’s leaders, including Stony Brook Lecturer Jason Lewis, Ludovic Slimak, cultural anthropologist at the University of Toulouse-Jean Jaurès, and Laure Metz, an archaeologist at Aix-Marseille University.

“Working with everyone so closely for that month definitely builds really strong connections that have lasted since,” said Victoria Greening, who graduated from Stony Brook in the winter and is planning to start a Master’s program in the fall at the University of Oxford.

She appreciated the opportunity to be a part of new discoveries.

“Working with something that’s not in the written records and discovering it yourself was a privileged feeling,” said Greening, who grew up in Yaphank.

A happy grown up

Echoing Gollum from the “Lord of the Rings” series, Slimak would look at something a student found and say, “my precious, this goes in a special bag,” Wong-Gómez recalled.

Slimak reflected the joy he took in discovering compelling finds. “It was amusing, watching a grown adult be so happy,” Wong-Gomez said.

Eva Marsh, who is a senior at Stony Brook in the anthropology department, appreciated the excitement of finding flint. A couple of students, she recalled, also found teeth, including a horse’s tooth. The group discovered a massive core, from which early Homo sapiens would chip off pieces to construct arrows they would shoot from a bow to bring down buffalo or horses.

On the first night gathering at their summer accommodations, Marsh said the group looked up at a star-filled sky.

“There was not a lot of pollution there” or other lights, which was “really amazing,” Marsh said.

Marsh was nervous on her first day, as she didn’t know what to expect. The team played games for the first few nights and discussed why they all signed up for the field experience. Each night at dinner, they discussed the events of the day, Marsh recalled.

For Svenya Drees, who grew up in Port Jefferson and is a Master’s Student in Lewis’s lab, the experience was familiar, as she had conducted field work during the summer of 2021. “I knew what to expect,” she said. Still, she found the discovery of pebbles from a distant river intriguing.

“There’s this whole mystery at the site about pebbles that made it into the assemblage,” Drees said. “These rocks were brought there from the local river. I thought that was pretty awesome.”

The theory about the pebbles is that Neanderthals or Homo sapiens, who had lived in the cave at different times, deployed the pebbles to help remove flakes from the rock cores these ancient ancestors used to create weapons.

Some challenges

While the students enjoyed the experience, with many of them planning to continue in their anthropological studies, the summer included some challenges.

The students stayed in a house at the top of a hill. At the same time, the cave was also on a hill. Each morning, they walked down the hill to a car that drove them to the bottom of the Grotte Mandrin site, where they walked about 15 minutes up to the field station. At the end of the day, they had to climb back up to their temporary home.

“After digging holes all day, walking up the hill was not my favorite part,” Wong-Gómez said. Greening suggested that future participants in the program, which will also run this summer, bring sturdy shoes.

The students also sometimes carried heavy containers filled with sand. The physical challenges notwithstanding, most of the students eagerly anticipate future such explorations.

“It’s definitely the right field for me,” said Greening. “Working at Mandrin solidified that for me.”

Wong-Gómez hopes to continue his field work at the University of Florida. The university has accepted him as a PhD student, although he is awaiting word on whether he gets funding.

“When I got the email that I was accepted, it didn’t feel real,” Wong-Gómez said. “I really want to do this.”

Have bow and arrow, will travel, even in Eurasia 54,000 years ago.

An archaeological site in the south of France that’s 70 miles from the coastline called Grotte Mandrin not only provided evidence that Homo sapiens and Neanderthals lived in this area around the same time, but also offered proof that early humans used bow and arrows to hunt for prey like bison and wild horses.

In research published in the journal Science Advances, Jason Lewis, a Lecturer in the Department of Anthropology at Stony Brook University; Ludovic Slimak, cultural anthropologist at the University of Toulouse-Jean Jaurès; and Laure Metz, an archaeologist at Aix-Marseille University, shared an extensive analysis of stone artifacts that demonstrated the use of bows and arrows.

These hunting tools, which inhabitants of the cave could use to pursue herd animals migrating between the Mediterranean region and the plains of Northern Europe, provide the earliest evidence of mechanically propelled projectile technology from Eurasia.

“We looked for diagnostic evidence of a very powerful impact once the stone tip hits something,” said Lewis. “We can see experimentally what type of damage” is produced on the tips of the arrows. The damage to these arrows is in line with everything that modern archers are doing because the tools human ancestors used were so light, Lewis added.

The collaborative effort to study these arrows in labs across two continents involved an extensive analysis of the flaking pattern around the tips of the arrows. The researchers didn’t find any of the organic materials that the early hunters would have used to create the bow.

This technology, which likely took about an hour to make, likely enabled Homo sapiens to bring down prey. Effective hunting from about 10 to 20 yards likely would have required more than one arrow, particularly with the size and strength of the targets.

At an archaeological site in the Middle East, scientists described stone tools around the same time that look similar to the bows and arrows humans in Eurasia used.

“The evolving modern humans were developing and using projectile technology,” Lewis said.  

Cultural differences

Lewis, Slimak and Metz showed in a seminal paper last year that Homo sapiens and Neanderthals had lived in the same cave, sometimes separated by a year or even a season.

While these two types of humans lived around the same time and in the same place, they didn’t share the same technology or have the type of cultural exchange that would enable Neanderthals, who typically hunted with hand-thrown spears, to use the same hunting tools.

“There’s no evidence of learning exchange,” Lewis said. Neanderthals did not start using the smaller points typical of the arrows or that would have been used as projectiles.

“It doesn’t look like there was a cultural exchange between the two groups,” Lewis said, as the artifacts from the time Neanderthals occupied the cave didn’t include any arrows.

Cultures sometimes develop identities that preclude using technology from other groups. Such cultural differences existed in the Maale and neighboring Tsamai people in Southwestern Ethiopia.

“Even though [bows and arrows] might be logically or objectively advantageous, some cultures suggest that ‘that’s not what we do,’” Lewis said.

Indeed, cultural differences have occurred in other areas that groups haven’t bridged, despite the availability of similar resources and the chance to learn the technology.

At the cave in Grotte Mandrin, researchers found a large collection of stone tools in Layer E of the cave.

The scientists believe the numerous arrows could have been the early equivalent of a munitions dump.

While bows and arrows would have provided a hunting advantage to Homo sapiens, the technology doesn’t explain why the two groups of early humans occupied the cave or dominated the area at different times.

“I doubt it comes down strictly to stone tool technology,” Lewis said. “There’s not a continuous march of occupation and expansion” as the interactions between the two populations were long lasting and complex.

Homo sapiens and Neanderthals moved up into a region and then moved back. This is akin to the way European settlers interacted with Native Americans when ships first crossed the Atlantic.

The Europeans moved into the region, interacted with people who already in the country, returned home, and then, at a later point crossed the ocean again.

Arrow studies

To understand the technology used to create these arrows, Metz and Slimak have spent years studying the way rocks flake off or get damaged in response to contact with animals or objects they hit when shot through the air.

Working for over a decade, Metz has been conducting experimental replication of the effect of use on these stone tools.

Scientists who shoot these stone arrows into carcasses from butcher shops can see the flaking pattern and scratches on the arrows.

Lewis explained that the flaking on the arrow heads could not have been made during the creation of the arrows themselves.

“Only high velocity strikes” could produce such markings, Lewis said.

These kinds of studies combine geology, physics and natural science. Lewis said John Shea, Anthropology Professor in the College of Arts and Sciences at Stony Brook University, has pioneered the study of such technology during the Pleistocene Ice Ages.

Lewis explained that his primary role is to bring the contextual understanding about how various types of early humans were using the landscape and interacting with the animals.

He also brings the context of work he does in Africa around the same time period as a comparator.

Lewis explained that more research would be forthcoming from this site.

“This is part of a larger modern human ability to conceptualize the world,” Lewis said. Early humans were trying to change their environment to match their needs, with boats, clothing, dwelling structures and other elements of their lives.

Such tool use could reduce hunting time and could enable a greater division of labor, suggesting that “each person didn’t have to do everything” to meet basic needs.

The No. 5/6 Stony Brook women’s lacrosse team (4-0) used a second half surge to come out on top and earn its third ranked win of the season against No.17 Stanford University (2-3) on March 3 at Snapdragon Stadium in San Diego, California.

The Seawolves were paced by CAA Preseason Midfielder of the Year, Ellie Masera, who tallied a season-high five goals. Graduate attacker Jolie Creo, senior attackers Kailyn Har and Morgan Mitchell and senior midfielder Erin MacQuarrie all added a pair of goals each in the contest.

Stony Brook got off to a slow start as the squad was not able to find the back of the cage in the first quarter and trailed the Cardinal 4-0 heading into the quarter break. Stanford would go on to tally two more goals within the first two minutes of the second quarter from Ashley Humphrey and Annabel Frist.
