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

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 ."

Neuromorphic camera and machine learning aid nanoscopic imaging

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

Mapping ATP's journey: Key protein identified as gateway for energy delivery into endoplasmic reticulum

Originally published by Stockholm University on May 21, 2025 edited by Sadie Harley , reviewed by Robert Egan   Scientists reveal how ATP is transported into the ER by the protein SLC35B1. Credit: Surabhi Kokane using Biorender. A team of scientists has answered a long-standing question in cell biology , uncovering h ow the cell's main energy currency, ATP , is transported into the endoplasmic reticulum ( ER ) . Disrupted energy transport could affect diseases such as type 2 diabetes, cancer, and neurodegenerative disorders . The study, " Step-wise ATP translocation into the ER by human SLC35B1 " published in Nature , confirms that the transporter protein SLC35B1 is the key gateway for ATP entry into the ER . The research , led by David Drew, professor of biochemistry at Stockholm University and located at SciLifeLab , reveals the first structural and mechanistic insight into how ATP enters the endoplasmic reticulum (ER) using the transporter protein SL...
