Unlike immunosenescence, inflammaging is a chronic low-grade inflammation in the absence of overt infection that occurs in aging, and may contribute to the clinical manifestations of other age-related pathologies; it is probably due to a loss of power of adaptive immunity and to a loss of control over systemic inflammation resulting in the release of pro-inflammatory cytokines, such as interleukin 6, the well-known molecule involved in those serious forms of COVID-19 characterized by «cytokine storm» [18,19,20,21]. This evidence concerns the gene IL6 and infection.
