Our results therefore show that (i) CMV infection is associated with statistically significant increases in cfPWV and CD4 Tmem in older men but not women, (ii) that CMV is linked to larger increases in CD4 Tmem in men than in women, and (iii) that the proportions of CD4 Tmem have a moderate but statistically significant positive association with cfPWV among CMV+ individuals. This evidence concerns the gene CD4 and cytomegalovirus infection.
