quel le rôle des interleukine? (what is the role of interleukins?)

They play a crucial role in the immune system, acting as chemical messengers that coordinate communication between different immune cells. They are essential for orchestrating a complex and multifaceted immune response. They play a critical role in various immune functions, including:
Fighting off infections caused by bacteria, viruses, and other pathogens

Cytokine is a general term used for small secreted proteins that are key modulators of inflammation. Cytokines are produced in response to invading pathogens to stimulate, recruit, and proliferate immune cells. Cytokines includes interleukins (IL), chemokines, interferons, and tumor necrosis factors (TNF). Cytokines are subdivided based on the nature of the immune response and the source of their production. From my research interest imbalance between pro- inflammatory and anti- inflammatory   cytokines are contributing in many diseases. Recently pro- inflammatory cytokines are related to all diseases through the gut microbiota- organ axis as hot point of research. Interestingly pro inflammatory cytokines and impaired gut microbiota was scientifically accepted to be involved in COVID-19 complications or “ long covid -19

These are signaling mediators responsible for cellular functioning. Important issue, poorly analyzed in humans.
