The Repeated Administration of Resveratrol Has Measurable Effects on Circulating T-Cell Subsets in Humans

Figure 4

The effects of resveratrol on the in vitro proliferation of human γδ T cells. PBMCs from healthy donors were cultured for seven days in T-cell medium stimulated with HMBPP in the presence of the indicated concentrations of resveratrol. The percentage of CD3⁺γδ T cells was determined by flow cytometry. (a) A representative flow cytometry result showing cells cultured with HMBPP alone (control) or with HMBPP together with resveratrol (resv). (b) A summary of the flow cytometry data showing the percentage of γδ T cells derived from three healthy individuals. (c) PBMCs from two healthy donors were cultured with HMBPP as a positive control or with various concentrations of resveratrol (resv) but without HMBPP. The percentage of γδ T cells was assessed in the same manner as (a). .
