Immunocytes Crosstalk Signaling Pathway The activation stimulus (such as bacteria, viruses, fungi and parasites, as well as mechanical injury and toxic stimuli) leads to the immune response. It is called specific, because recognition molecules should ideally be specific for a single ligand. The cells responsible for these immune responses include monocyte, mast cell, macrophage, neutrophil, eosinophil, basophil, B and T lymphocyte. These cells secret cytokines which are small proteins providing cells with the ability to communicate with one another and orchestrate complex multicellular behavior, therefore regulating diverse functions in the immune response including proliferation, differentiation, migration and function of immunocytes. The potency of cytokines, and the potential for amplification and damage which excessive cytokine production carries, has resulted in elaborate controls on cytokine production and action. Cytokines include interleukins (IL), interferons (IFN), chemokines, tumor necrosis factors (TNF) and growth factors that have been classified on the basis of their biological responses into pro- or anti-inflammatory catalogs, depending on their effects on immunocytes. https://www.creative-diagnostics.com/immunocytes-crosstalk-signaling-pathway.ht m
