ClinConnect Summary

CD8(+) cells are suppressor/killer lymphocyte cells that act to limit replication of viruses. It is hoped that the reinfusion of activated autologous CD8(+) cells into patients with AIDS will help to control opportunistic infections such as cytomegalovirus and toxoplasmosis (two of the leading causes of sickness and death in AIDS patients). This treatment may also stop the HIV virus from replicating (reproducing itself) in the AIDS patient. Further activation of these cells, once infused, may be necessary. It is hoped that IL-2 will stimulate the patient's immune system against the AIDS vir...
