Immune cells known as T cells help us clear invading microbes, such as HIV, from

our bodies, but they can also cause autoimmunity when they inappropriately

attack our own tissues. T cells are activated when a receptor on their surface

(the TCR) recognizes a specific complex of a peptide fragment bound to a protein

known as an MHC molecule.
