Figure 5. Age-related changes in CD4+ T cell compartment in BALF following the 2nd tuberculin challenge.

Figure 5.

(A) Number of CD4+ T cells in BALF of adult and aged macaques 48 hours post-tuberculin lung instillation (Week 16+48h). (B) Number of CD4+ T cells in BALF of adult and aged macaques 72 hours post-tuberculin lung instillation (Week 16+72). Number of CD4+ effector memory T cells (C) and CD4+ central memory T cells (D) 48 hours post-tuberculin lung instillation. Number of CD4+ effector memory T cells (E) and CD4+ central memory T cells (F) 72 hours post-tuberculin lung instillation. One-way ANOVA post-Tukey analyses comparing means between groups as indicated; *p<0.05. TST = tuberculin instillation; NaCl = saline (control) instillation.
