Fig. 1From: Analysis of cytomegalovirus-specific T-cell responses in patients with hypertension: comparison of assay methods and antigensAging was positively correlated with SBP and senescent CD8+ T-cell frequencies. We performed immunophenotyping of PBMCs obtained from 207 hypertensive patients. Increasing age was significantly associated with increased SBP (a), and increased frequencies of CD57+ cells (b) and CD28null cells (c) among total CD8+ T cellsBack to article page
