Medically reviewed by Robert Burakoff, MD Intestinal villi (singular: villus)are tiny, finger-like projections that line the interior (lumen) of the small intestine. The primary function of villi is ...

the small intestine is where the major digestion and absorption of nutrients take place. These nutrients are taken into the bloodstream, via millions of tiny, fingerlike projections called villi ...

Inability to absorb nutrients can lead to symptoms such as diarrhea and weight loss, but symptoms can also be very subtle.

Pathogen-fighting immune cells called tissue-resident memory CD8 T cells (TRM cells) go through a surprising transformation—and relocation—as they fight infections in the small intestine.

Pathogen-fighting immune cells go through a surprising transformation and relocation as they fight infections in the gut.

This discovery sheds light on how tissue-resident memory CD8 T cells adapt to their location in the body, ensuring a coordinated and effective immune response and how microenvironments and cellular ...

In the small intestine there are also specialised structures called villi which have a tiny hair-like structure poking into the small intestine to absorb digested food. If we stretched out all the ...
