Redness, hot pain as well as sepsis, are symptoms of the pathological process of infectious inflammation, a phenomenon that occurs with the participation of mediators produced by a large number of inflammatory cells, where cytokines are also involved. Cytokines are biologically active low molecular weight proteins or peptides secreted by various cells that regulate cell growth and differentiation, immune function, inflammation and wound healing. When pathogens invade or the body ages, inflammation cytokine signalling activate the body's immune system to defend against invaders. And when invaders are eliminated and the body needs to regain stability, anti-inflammatory cytokines are secreted. The constant interaction and balance between inflammatory and anti-inflammatory cytokines is an important part of the human immune system. https://cytokine.creative-proteomics.com/cytokines-in-inflammation.htm
