Bacteria in the human gut can directly deliver proteins into human cells, actively shaping immune responses. A consortium led ...

A Dartmouth study published in Nature Communications reveals that immune cells in the brain use a surprising two-step process ...

Scientists have uncovered a direct molecular mechanism by which gut bacteria inject proteins into human cells, reshaping immune responses and potentially driving inflammatory disease. Scientists have ...

Cancer cells carry thousands of mutations, but not all mutations are created equal. Some make tumors highly visible to the ...

To better understand why some cancer patients struggle to fight off infections, Georgia Tech researchers have created tiny lab-grown models of human immune systems. These miniature models—known as ...

A new method to keep human lymph node tissue alive and functioning outside the body for several days could give researchers a much clearer view of how our immune system responds to infections, ...

An initiative partly funded by the Wellcome Trust Sanger Institute in the UK has moved further towards its goal of producing a 'human cell atlas' (HCA) to map every cell type in the human body.

How does the same infection, say the flu or a cold, give some people mild symptoms and leave others suffering? Why do people develop autoimmune diseases? And will we ever be able to predict when—and ...

Human virus patterns have been spotted in the highlands of Ethiopia within a community of wild monkeys. Now, ASU is studying these patterns.

Oranges aren’t the only immune-supporting food. Red bell peppers, spinach, papaya, and ginger also provide key nutrients for ...
