Question

one marks answer how do cytokine barrier provide innate immunity in human

Answer 1

Cytokines play a vital role in the innate immune response by means of direct mechanisms which inhibit viral replication. Or else, by activating mechanisms for cells like NK cells and macrophages which produce more cytokines upon activation.

Cytokines are molecules which are used for cell-to-cell communication or cell signaling. They can communicate with the neighbouring or distant cells about initiating an immune response. They can also trigger cell trafficking or movement to a particular area of the body.

Answer 2

Cytokines play an important role in the innate response by acting against the invading agent during the beginning stages of infection. They form an innate immune system by forming physical barriers, general immune responses and defense mechanisms. This system protects the body against parasites, bacteria, viruses and foreign particles.
