Document Summary

Short term victim - the host cell that is being attacked (cd+ t helper cell) T helper cell is most vulnerable cell. The commanding officer of the immune system, central to activity of adaptive immune system. Key in responding to antigen presenting cells and identifying. The drum corps officer, the quarterback, delegating how to solve infections and stuff. Hiv-infected people with fewer than 200 cd4+ t-cells per cubic millimeter of blood. Diagnosed with at least one of two dozen aids-associated conditions that result from hivs destruction. Large amount of hiv in the peripheral blood. Adaptive immune system has identified this virus and created antibodies. Cytotoxic t cells (abt 3 weeks post infection) Stage 1 : primary (acute) hiv infection - s. Stage 2 : clinically asymptomatic - last for an average of 10 years; no. Major symptoms; hiv level in peripheral blood drops to very low levels; Know the graph - viral load/ cd4 cells, how many stages etc.
