- T-cells + B-cells that protect against pathogens
what triggers inflammation and what is it designed to do?
- triggered by “danger signals” released by macrophages (cytokines);
- designed to bring immune cells into damaged area
CD4 T cells:
helper cells that direct other immune cells to attack

social stressors –> quicker death
what is the Y in HIV and stress?
reduced anti-viral immune response
NE + HIV cells = ?
higher viral load
results of nonprimate research on stress and HIV:
stress increases viral replication; effects mediated by NE increase
what was the intervention in Antoni’s study?
CBSM: group based intervention + stress appraisal, coping skills, social support
