Mucus membranes How is the skin a natural barrier? WebCytokines are soluble proteins that act as communication signals between cells. In a nonspecific innate immune response, various cytokines may be released to stimulate production of chemical mediators or other cell functions, such as cell proliferation, cell differentiation, inhibition of cell division, apoptosis, and chemotaxis.
WebCytokines are molecules that are used for cell signaling, or cell-to-cell communication. Cytokines are similar to chemokines, wherein they can be used to communicate with neighboring or distant cells about initiating an immune response. Cytokines are also used to trigger … WebLeukocytes that provide innate immunity are derived from myeloid lineage. These cells include highly phagocytic, motile neutrophils; monocytes and tissue macrophages; eosinophils; and NK cells. These cells provide the first line of defense against most pathogens. Neutrophils are usually the first cell type to arrive at the site of tissue damage.
