Study links autoantibodies to long COVID symptoms

A new study reports that some people with long COVID make autoantibodies that attack brain and nerve tissue. When researchers gave these antibodies to mice, the animals developed pain, fatigue and balance problems similar to patient symptoms.

Diet compound may help repair gut damage in HIV

A primate study found a broccoli-based supplement that raises dietary indoles was linked to signs of improved intestinal barrier repair in treated infection. The results are preliminary and need confirmation in humans.

Newborn antibiotics change gut bacteria and lung immunity

Researchers at University of Rochester Medicine report that antibiotics given to newborns can alter gut bacteria and reprogram lung immune cells in mice and humans. These changes can last into young adulthood and may affect breathing.

New mucosal EV vaccine with inverted HA may protect against many flu strains

Researchers report a vaccine approach using cell-derived extracellular vesicles that display inverted influenza hemagglutinin proteins. Tests in mice showed broad immune responses after intranasal dosing, suggesting potential for a universal mucosal flu vaccine.

Some chemotherapy drugs trigger immune attack by mimicking viruses

New research finds that some chemotherapy agents can make cancer cells behave like virus‑infected cells. This viral mimicry activates the innate immune system and could let doctors use lower drug doses with better results.

Gut bacterium protects mice from deadly pneumonia after flu

A study in Science Immunology reports that segmented filamentous bacteria (SFB) in the gut protected mice from lethal bacterial pneumonia after influenza A infection by reprogramming lung immune cells.

New oral Listeria vaccine shows promise against colorectal cancer

Researchers report a modified oral vaccine made from Listeria that primes immune cells in the gut and limits tumor growth in mice. The vaccine worked best when combined with immune checkpoint inhibitors and caused few side effects.

Atlas maps how aging reshapes cells

Scientists at Rockefeller University profiled nearly 7 million cells from 21 organs in mice at three ages. The atlas reveals cell-type shifts, coordinated changes across organs, strong sex differences and genomic sites linked to immunity.

Immune cells may explain why women have longer pain

New research finds that a subset of immune cells, monocytes, release interleukin-10 (IL-10) to switch off pain. These IL-10-producing cells were more active in males, a difference linked to sex hormones and seen in mice and people.

New inflammatory pathway may explain some rheumatoid arthritis treatment failures

A Washington State University study found that a lesser-known TWEAK–Fn14 pathway can join with TNF to increase inflammation. Blocking Fn14 reduced this surge and may explain why some patients do not respond to TNF inhibitors.

COVID-19 and Flu: Lasting Effects on Lungs and Brain

A mouse study found that even mild COVID-19 or influenza can cause lasting changes in lungs and brain after infection clears. COVID-19 produced unique, persistent brain inflammation and tiny bleeding not seen after influenza.

Everyday discrimination and the immune system

A US study of adults aged 50 and older found that routine unfair treatment is linked to more exhausted immune cells. Researchers say social stress may leave biological traces, but they call for more research to confirm this.

Adding antibodies could make flu vaccines cut spread

New research shows adding certain infection-made antibodies to flu vaccines may lower how much infected people spread the virus. The study followed households using tests and models and was published in Nature Communications.
