The stage for our immune system's development is set very early in life. Research over the past two decades has pointed toward microbes in the infant gut playing a key role.

Researchers from Freiburg and Ulm discover mechanism through which bacteria attack white blood cells. A research team led by Prof. Dr. Winfried Römer and Dr. Elias Hobeika from the University of ...

Ubiquitin is one of several post-translational modifications known to modulate the STING cascade’s immune response. The team found that VP1-2 was targeting the STING activity in brain immune ...

Regulatory T cells, which are part of the body's immune system, downregulate the activity of other immune cells, thus preventing the development of autoimmune diseases or allergies. Scientists at ...
