There are four types of T cells, each with a special purpose. Helper T cells detect infection and get the other cells of the immune system ready for battle. Helper T cells also tell B cells to produce antibodies, highly specialized proteins that help defend the body against infection. Cytotoxic, or killer, T cells destroy infected cells. Regulatory T cells tell the immune system when the battle with the pathogens is over and to stop fighting. Memory T cells remember how to defeat an infection and can respond rapidly if the same infection reoccurs.

A kidney transplant is a surgical operation that places a functioning kidney from a donor into your body. The transplanted kidney takes over the work of the kidneys that failed, and you no longer need dialysis. In most parts of the country the waiting list to get a transplanted kidney ranges from 3-5 years or longer.
