Researchers from the Saint Louis University have discovered that potentially aggressive T-cells that might lead to autoimmune disease can instead be enlisted to help ‘police’ over-active immune responses, via the molecule CD5.  The team explain that the immune system maintains health by avoiding the dangers of over- and under-responses. People with immune systems that do not efficiently fight off pathogens, like viruses or bacteria, will … Continue reading Newly differentiated T-cell ‘policemen’ can lower autoimmune disease risk.
