Abstract
We evaluated in vivo innate immune responses in monocyte populations from 67 young (age 21-30) and older (age≥65) adults prior to and following influenza vaccination. We found that CD14+ CD16+ inflammatory monocytes were induced following vaccination in both young and older adults. In classical CD14+ CD16- and inflammatory monocytes, TNF-α and IL-6 production as measured by intracellular staining were strongly induced following vaccination. Cytokine production was strongly associated with influenza vaccine antibody response; highest levels were found as late as day 28 post-vaccine in young subjects, and were substantially diminished in older subjects. Notably, levels of the anti-inflammatory cytokine IL-10 were markedly elevated in monocytes from older subjects pre- and post-vaccine. In purified monocytes, we found age-associated elevation in phosphorylated STAT3, and decreased serine 359-phosphorylation of the negative IL-10 regulator DUSP1. These findings for the first time implicate dysregulated IL-10 production in impaired vaccine responses in older adults.
