Figure 4. Kinetics of TFR, TFH and TREG after SIV infection.

Figure 4

(A) Frequency of TFH, TFR and TREG as percentage of the total CD4+ T-cell population within lymph nodes of uninfected, acutely (week 2) SIV-infected and chronically (week 24) SIV-infected RM. (B) Frequency of TFR as a percent of TFH within the lymph nodes of the same animals. (C) Ratio of frequencies of TFR to the frequency of TFH (both calculated as a percent of the total CD4+ T-cell population). (D) Percent of proliferating, Ki67+, TFH, TFR and TREG within the lymph nodes of uninfected, acutely SIV-infected and chronically SIV-infected RM. Statistical analyses were performed using Mann-Whitney U tests.
