Analysis of Th17 and Tc17 Frequencies and Antiviral Defenses in Gut-Associated Lymphoid Tissue of Chronic HIV-1 Positive Patients

Figure 1

Activation markers, IFN-γ and IL-17A expression in CD4⁺ and CD8⁺ T cells subsets in blood and in gut. Panel (a): representative flow cytometry plots outlining CD38 and HLA-DR expression on naïve, effector, and central memory CD4⁺ and CD8⁺ lymphocytes derived from peripheral blood mononuclear cells (PBMCs) and gut-associated lymphoid tissue (GALT). Panel (b): representative flow cytometry plots outlining IFN-γ and IL-17A intracitoplasmatic expression on naïve, effector, and central memory CD4⁺ (Th1 and Th17) and CD8⁺ (Tc1 and Tc17) lymphocytes derived from PBMCs and GALT.
