Fig 2. Frequency of T and NK cells in GALT from HIV controllers and progressors.

Rectal cells were incubated with monoclonal antibodies against human molecules on (A) CD4⁺ T-cells. (B) CD8⁺ T-cells. (C) Total NK cells, and detected by flow cytometry as described in Materials and Methods. The black line represents the median. A Mann Whitney test was used with a confidence level of 95%. Significant differences are indicated at the top of the figure. (*p<0.05, **p<0.01).
