LA JOLLA—Salk Institute physician-scientist Jesse Dixon has been named a Rita Allen Foundation Award Scholar, a distinction given to biomedical scientists whose research holds exceptional promise for revealing new pathways to advance human health.
LA JOLLA—The prevalence of colorectal cancer in people under the age of 50 has risen in recent decades. One suspected reason: the increasing rate of obesity and high-fat diets. Now, researchers at the Salk Institute and UC San Diego have discovered how high-fat diets can change gut bacteria and alter digestive molecules called bile acids that are modified by those bacteria, predisposing mice to colorectal cancer.
LA JOLLA—Glioblastoma, the most common and deadly form of brain cancer, grows rapidly to invade and destroy healthy brain tissue. The tumor sends out cancerous tendrils into the brain that make surgical tumor removal extremely difficult or impossible.
LA JOLLA—The Salk Institute welcomes Assistant Professor Agnieszka Kendrick, a structural biologist who studies how cells recognize and transport cargo within the cell.
LA JOLLA—Although infections can present with many different symptoms, one common symptom is the loss of fat and muscle, a process called wasting. Salk scientists wanted to know whether wasting was beneficial in fighting infections.
LA JOLLA—Salk Institute researchers, in collaboration with the National Institutes of Health, have discovered the molecular mechanisms by which the human immunodeficiency virus (HIV) becomes resistant to Dolutegravir, one of the most effective, clinically used antiviral drugs for treating HIV.
Margaret Faye Wilson, a leader in the banking and retail industries, died on July 10. She served as a Trustee on Salk’s Board from 2010 to 2019 and was a generous donor of the Institute over the years, including supporting the Institute’s premier annual event, Symphony at Salk.
LA JOLLA—On Saturday, August 19, the Salk Institute will celebrate 27 years of Symphony at Salk, its premier annual fundraiser and concert under the stars, with the breathtaking sounds of the San Diego Symphony and guest performer Jennifer Hudson, a two-time GRAMMY Award-winning recording artist, Academy Award-winning actress, and Tony and Emmy Award-winning producer.
LA JOLLA—The life of the tiny worm called Caenorhabditis elegans consists mostly of looking for food, eating food, and laying eggs. So, when any of these behaviors are disrupted, there’s cause for concern. In a new study, Salk Institute scientists discovered that the “feel good” brain chemical dopamine regulates anxious worm behavior in the presence of nipping predators.
LA JOLLA—Worldwide, more than a million deaths occur each year due to diarrheal diseases that lead to dehydration and malnutrition. Yet, no vaccine exists to fight or prevent these diseases, which are caused by bacteria like certain strains of E. coli. Instead, people with bacterial infections must rely on the body taking one of two defense strategies: kill the intruders or impair the intruders but keep them around. If the body chooses to impair the bacteria, then the disease can occur without the diarrhea, but the infection can still be transmitted—a process called asymptomatic carriage.
LA JOLLA—The Salk Institute welcomes Assistant Professor Daniel Bayless, a neurobiologist who studies the influence of sex hormones on social interaction and behavior in mice. Bayless joins Salk’s world-renowned neuroscience faculty—a collaborative team working to uncover how our brains work so we can build resilience in the face of stress, aging, and disease.
LA JOLLA—The immune system protects the body from invaders, such as bacteria, viruses, or tumors, with its intricate network of proteins, cells, and organs. Specialized immune cells, called cytotoxic T cells, can develop into short-lived effector cells that kill infected or cancerous cells within our bodies. A small portion of those effector cells remain after an infection and become longer-lived memory cells, which “remember” infections and respond when infections reappear. But little was known about what influences cytotoxic T cells to transform into these effector and memory T cell subtypes.
LA JOLLA—The cellular life inside a plant is as vibrant as the blossom. In each plant tissue—from root tip to leaf tip—there are hundreds of cell types that relay information about functional needs and environmental changes. Now, a new technology developed by Salk scientists can capture this internal plant world at an unprecedented resolution, opening the door for understanding how plants respond to a changing climate and leading to more resilient crops.
LA JOLLA—Françoise Gilot, artist, best-selling author, and wife of the late Salk Institute founder and vaccine pioneer Jonas Salk, died on June 6 at a hospital in Manhattan at the age of 101.
LA JOLLA—Situated at the intersection of the human immune system and the brain are microglia, specialized brain immune cells that play a crucial role in development and disease. Although the importance of microglia is undisputed, modeling and studying them has remained a difficult task.
LA JOLLA—In addition to communicating with neurotransmitters, the brain also uses small proteins called neuropeptides. Neuropeptides send signals between neurons, working similarly to neurotransmitters but with key differences like a greater size and an ability to travel far away from the neuron that produces them. Though their importance is widely recognized, the way neuropeptides move around the brain and influence neurons has remained poorly understood—until now.
LA JOLLA—The Salk Institute and Autobahn Labs, an early-stage drug discovery incubator, will work together to identify and advance promising initial scientific discoveries through the preliminary steps of drug discovery and development. Autobahn Labs will invest up to $5 million per project for Salk discoveries that require access to drug development expertise and state-of-the art capabilities.
LA JOLLA—Five Salk Institute faculty members have been promoted for their notable, innovative contributions to science. These faculty members have demonstrated leadership in their disciplines, pushing the boundaries of basic scientific research. Assistant Professors Sung Han, Dmitry Lyumkis, and Graham McVicker were promoted to associate professors, and Associate Professors Sreekanth Chalasani and Ye Zheng were promoted to professors. The promotions were based on Salk faculty and nonresident fellow recommendations and approved by Salk’s president and Board of Trustees on April 21, 2023.
LA JOLLA—Salk Institute Professor Susan Kaech, director of the NOMIS Center for Immunobiology and Microbial Pathogenesis, has been elected to the American Academy of Arts and Sciences. She shares the honor with some of the world’s most accomplished leaders from science and technology, business, public affairs, education, the humanities, and the arts. Kaech and the new class of nearly 270 members will be inducted at a formal ceremony on September 30, 2023, at the Academy’s headquarters in Cambridge, Massachusetts.
LA JOLLA—Scientists often act as detectives, piecing together clues that alone may seem meaningless but together crack the case. Professor Reuben Shaw has spent nearly two decades piecing together such clues to understand the cellular response to metabolic stress, which occurs when cellular energy levels dip. Whether energy levels fall because the cell’s powerhouses (mitochondria) are failing or due to a lack of necessary energy-making supplies, the response is the same: get rid of the damaged mitochondria and create new ones.
Your partnership allows our scientists to accelerate the pace of high-risk, high-reward discoveries that have the potential to benefit the health of all humanity-be it cancer, Alzheimer’s disease, climate change, infectious diseases or more.
