Question

How to cytokine barriers provide innate immunity in humans?

Answer 1

Cytokines play a main role in the innate immune response by means of direct mechanisms against the invading agent (inhibiting viral replication) or by activating mechanisms for cells such as NK cells and macrophages, which upon activation, produce more cytokines

Answer 2

Alternatively, innate immunity holds an infection in check until the slower adaptiveimmune response can be mounted. ...Innate immune mechanisms include anatomical and physiological barriers, inflammation, complement activation,cytokine secretion, target cell lysis, phagocytosis and autophagy.
