How the benefits of vaccination extend beyond protection from infection
Vaccination not only prevents disease caused by acute infection but also protects against long-term immune-related sequelae that can follow an acute viral infection. This is the main conclusion of a study led by the Infection ...

Immune cell map uncovers how individual aging trajectories diverge
While birthday candles measure the number of years someone has lived, they don't always tell the full story about someone's health. Two people born on the same day can have immune systems that age differently, leaving some ...

Rogue lipids: How routine cellular stress can fuel chronic inflammation
Oxidized lipids—fats structurally altered by enzymes, oxygen or free radicals—are double-edged swords that can both quell and ignite systemic inflammation, according to a new comprehensive review aimed at sharpening the overall ...
Shifting immune cells toward cancer-fighting mode: Sugar-coated extensions reveal a potential target
Our bodies contain immune cells called macrophages. Normally, these cells attack and suppress bacteria and cancer cells. However, when macrophages infiltrate tumors, they can become tumor-associated macrophages (TAMs) and ...

'Immune fog' may flag lung cancer risk years before tumor develops
A 'rising fog' may cloud the immune system's ability to detect tumors and may be the key to tackling lung cancer that is developing years before diagnosis. The team at University College London (UCL) followed this signal ...

Abdominal fluid reveals rare immune cells that may limit attacks on tumors
In a study published in Science Immunology, researchers used malignant ascites—fluid that accumulates in the abdomen of some patients when cancer metastasizes to the abdominal cavity—to uncover immune programs associated ...

Allergic to gold jewelry? Lab tests reveal gold can dissolve from earrings under specific chemical conditions
Gold has a reputation for being chemically untouchable. But according to Western University chemist Yolanda Hedberg, that reputation is a little misleading—gold is not unreactive so much as selective about what it reacts ...

Human lung organoids with a built-in immune system could transform respiratory disease research
A new organoid model built with human lung fragments may help us answer key questions about one of the body's first lines of defense against respiratory pathogens. In a new study, researchers at the Stanford University School ...

Parasitic worms could hold the key to treating immune system diseases
For millions of years, parasitic worms have had to survive inside animals without being destroyed by their hosts' immune systems. To do that, they have evolved remarkably effective ways of dampening the immune response.

Of mice and zebrafish: How scientists solved a decades-old mystery and uncovered new insights about inflammation
Sometimes you can solve a mystery with a fish but not a mouse. Sometimes you can see a biochemical process happening, but you can't study it in detail until you identify the underlying players. Sometimes separate streams ...

Brain immune cells protect neurons in Parkinson's disease by 'nibbling' harmful material
Researchers at the University of Oxford have uncovered a previously unrecognized protective role for microglia, the brain's resident immune cells, in Parkinson's disease. The study shows that a distinct population of human ...

One dose of protein-targeting CAR-T cells shrinks solid tumors in preclinical tests
CAR-T cell therapies have fundamentally transformed the treatment of several blood and lymph node cancers. However, their use in solid tumors such as liver, breast or lung cancer has so far been significantly more difficult. ...
