Tregs tagged posts

With insights into a molecular pathway that regulates the activity of Tregs, a type of T cell involved in immunosuppression, new research opens up possibly new avenues for treating inflammatory and autoimmune diseases.

Immune response is a balancing act: Too much can lead to inflammatory or autoimmune disease; too little could lead to a serious infection...

A single protein from a worm parasite may one day offer new therapeutic options for treating inflammatory bowel diseases like Crohn’s or Ulcerative Colitis, that avoid the potentially serious side effects of current immunosuppressant medications. The study, published today in Nature Communications, demonstrates the discovery of a distinct new worm protein which mimics a cytokine found in humans, known as transforming growth factor-beta (TGF-β). The newly-discovered protein switches off inflammation by inducing “regulatory T cells”, the body’s own means of dampening excessive reactivity.

The “Hygiene Hypothesis” suggests that some bugs and parasites may protect you from an overly-rea...

The presence of microbes specifically blocks the immune cells responsible for triggering allergies. It is well known the microbiota is involved in many mechanisms, including digestion, vitamin synthesis and host defense.The hygiene hypothesis suggests a link between a decline in infectious diseases and increase in allergic diseases in industrialized countries. Improvements in hygiene levels lead to reduced contact with microbes that is paralleled by an increased incidence in allergic and autoimmune diseases, eg type 1 diabetes.

Epidemiological studies have substantiated this hypothesis, by showing children living with farm animals – and thus with more microbial agents – develop fewer allergies during their lifetime...
