A research team has discovered a previously unknown mechanism by which the immune system fights bacterial infections. The ...

The key obstacle against the cure of human and simian immunodeficiency virus (HIV/SIV) infections is the reservoir of proviruses, which are robustly incorporated into the genomes of host CD4+ T cells.

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 ...

As well-researched as the immune system is, it still regularly manages to throw us a surprise or two. The latest discovery? A whole new mechanism that’s been hidden all along in cells' garbage ...

Effective functioning of the immune system relies upon systems of checks and balances; too little activity results in overwhelming infection, too much activity results in excessive damage to the host.

Globally, breakthrough COVID-19 infections among vaccinated people are increasing, raising concerns about the durability of protection against emerging, highly contagious variants of concern. A study ...

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 ...

The immune system is designed to protect us against viruses and bacteria. In autoimmune diseases, however, the immune system ...

New insights into a sophisticated process that protects sperm cells has revealed a mechanism, similar to an immune system, thwarts genetic chaos during the earliest stages of their development.

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 ...
