(Press-News.org) LA JOLLA (July 23, 2024)—Salk Professor Janelle Ayres has been selected as a 2024 Howard Hughes Medical Institute (HHMI) Investigator. The HHMI Investigators program awards established scientists with approximately $9 million in funding over seven years to pursue boundary-breaking research in their field. The honor recognizes her influential work in immunology and microbiology and its applications to the global crisis of antibiotic resistance.
Ayres is among 26 other 2024 selectees, who will join more than 250 standing Investigators—including Salk Professors Joanne Chory (1997), Joseph Ecker (2011), and Kay Tye (2021).
“Janelle’s research on microbial pathogenesis has greatly enhanced our understanding of host-microbe interactions,” says Salk President Gerald Joyce. “Receiving this support from HHMI is a wonderful recognition of her achievements thus far and her potential for continued excellence in the years ahead.”
Ayres is head of the Molecular and Systems Physiology Laboratory, a member of both the Gene Expression Laboratory and the NOMIS Center for Immunobiology and Microbial Pathogenesis, and holder of the Salk Institute Legacy Chair.
Ayres’ discovery of the “Cooperative Defense System” has radically shifted scientists’ perspectives on health and disease. Rather than thinking of health as simply the absence of disease, Ayres describes health as an active biological process requiring unique endurance and resilience mechanisms—altogether dubbed the Cooperative Defense System.
A major principle of this work is the revelation that a person or “host” infected with a pathogen does not need to kill the pathogen to survive. Rather, they can avoid disease by learning to adapt and cooperate with the pathogen.
Ayres’ findings have sweeping therapeutic applications. In 2023, Ayres applied these principles to a study of diarrheal infections, as well as the process of cachexia (losing fat and muscle stores during disease). Her research on diarrheal infections revealed a new potential vaccine strategy for diarrheal diseases and other infections, while her research on cachexia revealed that muscle loss surprisingly contributes to the management of disease.
The clinical implications of Ayres’ work will fuel her future research as an HHMI Investigator. Her new experiments will dig deeper into the factors that make the difference between an infected individual who remains healthy, and one that becomes sick and dies. As these differences and their mechanisms become clearer, she will be able to reveal new strategies to treat infections that can address the global crisis of antibiotic resistance, better ensure patient survival when infected, and better prepare us for the next pandemic when it happens.
To maximize the impact of this work, Ayres can now lean on her HHMI community of trusted colleagues for additional scientific support and outreach.
Ayres’ other recent achievements include a $1 million grant from the W. M. Keck Foundation, the NIH Director’s Pioneer Award in 2018, and induction into the American Academy of Microbiology’s Fellowship Class of 2024. She was the 2018 recipient of the Blavatnik National Award for Young Scientists for Life Sciences, one of the world’s largest unrestricted prizes for early career scientists.

Blood pressure high for years? Beware of stroke risk
2024-07-23
High blood pressure is known to increase a person’s chances of having a stroke.
But a study led by Michigan Medicine narrows in on the cumulative effects of years of high systolic blood pressure — the top number on the blood pressure reading and how hard the heart pumps blood to the arteries — finding that a higher average reading during adulthood is linked with a greater risk for the two most common types of stroke.
The study, published in JAMA Network Open, analyzed the average systolic blood pressure years ahead of the first stroke for more than 40,000 people ...

New car smell reaches toxic levels on hot days
2024-07-23
A study of volatile organic compounds (VOCs) emitted by new cars on hot summer days finds concerning levels of formaldehyde and other aldehydes. Consumers are familiar with—and even drawn to—the “new car smell” produced as VOCs from carpets, upholstery, and other interior materials in newly manufactured passenger vehicles. These VOCs can cause a range of health effects, including headaches, inflammation of the eyes, nose and throat, fatigue, irritability, dry cough, lung disease, and disorientation. Jianyin Xiong, Shaodan Huang, and colleagues sought to capture the levels of VOCs in the passenger cabins of new cars on ...
A promising new method uses light to clean up forever chemicals
2024-07-23
Perfluoroalkyl substances (PFASs), nicknamed ‘forever chemicals,’ pose a growing environmental and health threat. Since the invention of Teflon in 1938, PFASs and perfluorinated polymers or PFs have been widely used for their exceptional stability and resistance to water and heat. These properties made them ideal for countless applications, from cookware and clothing to firefighting foam. However, this very stability has become a major problem. PFASs do not easily break down in the environment, leading ...
DIF-1(+3): Combating drug-resistant malaria parasites
2024-07-23
Malaria remains a serious health issue globally, especially in Africa. The disease is caused by protozoan parasites in the Plasmodium genus. In 2021, there were 247 million cases of malaria and 619,000 deaths reported worldwide. At present, the first line of treatment against malaria is artemisinin combination therapy (ACT) and the administration of artemisinin derivatives in combination with other drugs. After the introduction of ACTs in Africa, which accounts for more than 90% of the world’s malaria cases, the number of deaths due to malaria greatly declined in the mid-2000s. However, Plasmodium falciparum, the most virulent malaria parasite, is resistant to ACT and has been spreading ...
Can a World Cup run drive interest in a nation? New study finds evidence of the “flutie effect” off the field
2024-07-23
Nearly four decades ago, Boston College quarterback Doug Flutie launched a game-winning, mid-field touchdown pass to upset the University of Miami on the game’s final play—prompting a subsequent surge in applications to the school in what has been dubbed the “Flutie Effect.”
A team of NYU researchers has now found evidence of this effect beyond the gridiron—and athletic competition. During and after Morocco’s surprising run to the World Cup semi-finals in the fall 2022, online searches on non-sports topics related to Morocco increased ...
