Abstract
Respiratory syncytial virus (RSV) infections in elderly individuals are associated with increased rates of severe clinical disease and mortality compared to younger adults. Age-associated declines in numerous innate and adaptive immune parameters during RSV infection contribute to infection susceptibility, impaired viral clearance, and distorted cytokine profiles in the elderly. Impaired immune responses in this age group also adversely affect longevity of RSV immunity following vaccination in experimental settings. This review summarizes the effects of aging on cellular immune responses to RSV in humans and animal models, molecular mechanisms for these impaired responses where they have been elucidated, and the clinical consequences of impaired immunity in the elderly.
期刊介绍：
Launched in 1955, Virology is a broad and inclusive journal that welcomes submissions on all aspects of virology including plant, animal, microbial and human viruses. The journal publishes basic research as well as pre-clinical and clinical studies of vaccines, anti-viral drugs and their development, anti-viral therapies, and computational studies of virus infections. Any submission that is of broad interest to the community of virologists/vaccinologists and reporting scientifically accurate and valuable research will be considered for publication, including negative findings and multidisciplinary work.Virology is open to reviews, research manuscripts, short communication, registered reports as well as follow-up manuscripts.
