Question

how do cytokine barrier provide innate immunity in humans

Answer 1

If any antigen gets through the chemical and physical barriers, innate immunity provides a first line of defense. The innate immunity system provides the first non-specific defense barrier of the pig. In this type of response cytokines play a very important role, both directly (for example, blocking viral replication by the interferons) and by means of different immune-modulatory mechanisms that trigger the inflammatory response, produce and elevation on the body temperature, activate NK cells and macrophages, etc. Those cytokines that have a role in this step are mainly produced by monocytes-macrophages and other non-immunological cells, such as fibroblasts and endothelial cells.



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.
The main cytokines that have a role in the innate response are:

Answer 2

Answer:

Explanation:

Cytokine inhibits viral replication. They form an innate immune system by forming physical barriers. Cytokine barriers: Virus-infected cells secretes proteins call interferons which protect non-infected cells from further viral infection.
