08/29/25Salk Institute Leveraging microproteins to treat obesity, aging, and mitochondrial disorders LA JOLLA—Like bees breathing life into gardens, providing pollen and making flowers blossom, little cellular machines called mitochondria breathe life into our bodies, buzzing with energy as they produce the fuel that powers each of our cells. Maintaining mitochondrial metabolism requires input from many molecules and proteins—some of which have yet to be discovered. Read more

08/07/25Salk Institute Finding microproteins to treat obesity and metabolic disorders LA JOLLA—The obesity rate has more than doubled in the last 30 years, affecting more than one billion people worldwide. This prevalent condition is also linked to other metabolic disorders, including type 2 diabetes, cardiovascular diseases, chronic kidney disease, and cancers. Current treatment options include lifestyle interventions, bariatric surgery, and GLP-1 drugs like Ozempic or Wegovy, but many patients struggle to access or complete these treatments or to maintain their weight loss afterwards.

07/29/25Salk Institute How does the immune system prepare for breastfeeding? LA JOLLA—Of the 3.6 million babies born in the United States each year, around 80 percent begin breastfeeding in their first month of life. Breastfeeding has known benefits for both mother and child, reducing maternal risk of breast and ovarian cancers, type 2 diabetes, and high blood pressure, while simultaneously supporting the baby’s nutrition and immune system. But because pregnancy and lactation have been historically understudied, we still don’t understand the science behind many of these benefits. Read more

07/24/25Salk Institute Salk Professor Diana Hargreaves earns V Foundation award for pancreatic cancer research LA JOLLA—Salk Institute Professor Diana Hargreaves was named a 2025 All-Star Translational Award Program grantee by the V Foundation for Cancer Research. The award comes as a recognition of Hargreaves’ exceptional success with her previous V Foundation grant in 2016, which aimed to identify better drug targets for cancers with mutations in a multi-protein complex called SWI/SNF that regulates DNA structure and stability. She and her collaborator, Gregory Botta, an associate professor at UC San Diego Moores Cancer Center, will receive $1 million to advance her new project to improve immunotherapy—a treatment that utilizes the body’s own immune cells to fight cancer—in patients with pancreatic cancer.

05/23/25Salk Institute Action! Proteins critical to healthy brain development captured on film LA JOLLA—Our cells rely on microscopic highways and specialized protein vehicles to move everything—from positioning organelles to carting protein instructions to disposing of cellular garbage. These highways (called microtubules) and vehicles (called motor proteins) are indispensable to cellular function and survival. Read more
