A trio of researchers has won the 2025 Nobel Prize in Physiology or Medicine for discovering how the immune system is prevented from attacking our own bodies.

Mary E. Brunkow of the Institute for Systems Biology in Seattle, Fred Ramsdell of Sonoma Biotherapeutics in San Francisco, and Shimon Sakaguchi of Osaka University in Japan were awarded the prize "for their discoveries concerning peripheral immune tolerance." The Nobel Assembly at KarolinskaInstitutet announced the winners at a ceremony in Stockholm, Sweden, on Monday (Oct. 6).

Neuromorphic camera and machine learning aid nanoscopic imaging by Indian Institute of Science Transformation of cumulative probability density of ON and OFF processes allows localisation below the limit of classical single particle detection. Credit: Mangalwedhekar et al In a new study, researchers at the Indian Institute of Science (IISc) show how a brain-inspired image sensor can go beyond the diffraction limit of light to detect miniscule objects such as cellular components or nanoparticles invisible to current microscopes. Their novel technique, which combines optical microscopy with a neuromorphic camera and machine learning algorithms, presents a major step forward in pinpointing objects smaller than 50 nanometers in size. The results are published in Nature Nanotechnology. Original article

Rare lung immune cells act as peacekeepers against deadly COVID-19 inflammation

O riginally published by NYU Langone Health on April 25, 2025 Credit: Pixabay/CC0 Public Domai n A rare cell type in the lungs is essential to survival from the COVID-19 virus , a new study shows. Experiments in mice infected with the SARS-CoV-2 virus revealed that the immune cell class in question, called nerve and airway-associated interstitial macrophages , or NAMs , may keep the human immune system's initial counterattack on the virus ( lung inflammation ) from spiraling out of control to endanger patients. Macrophages are known to be the first responders to infection , as large immune cells capable of devouring invading viruses and the cells they infect . Led by researchers at NYU Langone Health , the study shifts the focus for treating the disease away from strengthening the immune system attack on the virus and toward better restraint of the immune response , what researchers call " disease tolerance ."
