HIV: Identification of key immune response receptors in patients spontaneously controlling infection


A small number of patients infected by HIV spontaneously control viral replication without antiretroviral therapy, and do not develop the disease. The ability of these rare patients, known as "HIV controllers", to suppress HIV replication appears to be down to a highly effective immune response. Scientists observed that CD4+ T immune cells in these patients were capable of recognizing tiny quantities of the virus.
