T cells, in the thymus they dwell, fighting all villains, visible or hidden. T helpers, with MHC class- I, they shelter. Th1, Th2, Th17, the list goes on umpteen. Regulatory T cells, like a principal, regulate all the cells. T cytotoxic, to MHC class -II, they are patriotic, interact with perforin and granzyme. Together these cells, work just fine, keeping our immunity in line.
