,Types of adaptive immunity
, • Viruses are one of the major dangers that we face in everyday life,
so our immune system has powerful methods to fight them
• Our cells call for help when they become infected, by displaying
little pieces of the viruses (peptides) on their surface (MHC)
• When the immune system finds these viral peptides, it quickly kills
the infected cell and the viruses inside
• Recall: How MHC presents antigens
• We will now look at the T-cells and their receptors, the protein that
recognizes these viral peptides.
