A new mechanism that slows down and may even prevent the natural aging of immune cells -- one of the nine 'hallmarks of ageing' -- has been identified by an international team. A new mechanism that ...

Medical scientists have demonstrated that important pro-inflammatory mediators are released into the bloodstream through tiny pores in the cell membrane at a very early stage of the immune response.

A mechanism of antiviral immunity in bacteria has been characterized. A research team from Umeå University (Sweden) has uncovered a mechanism for how bacteria build up antiviral immunity against ...

Our bodies response to invading pathogens through different mechanisms of the immune system. Innate immunity first detects disease and relays a defense signal to activate the second wave of immune ...

In chronic hepatitis B, the liver contains immune cells that could destroy hepatitis B virus infected cells but are inactive. A team from the Technical University of Munich (TUM) has discovered that ...

SUMOylation is a biochemical process that peppers proteins with small ubiquitin-like modifiers (SUMOs). Earlier studies have shown SUMOylation suppresses type I interferon (IFN1) signaling that helps ...

The immune system going rogue and attacking healthy tissue seems to behind some cases of long covid, a discovery that could ...

Plant immunity is largely initiated at the cellular level, with each cell capable of autonomous detection and response, while also coordinating systemic signaling across the organism—unlike the ...

Of all the fungi that live in the human body, the most infamous is probably the yeast Candida. This distant cousin of baker's yeast is notorious for causing various types of thrush that can be a major ...
