Cytokines bacteria
WebCytokines signal cells to move to certain area in the body where the particle (in our case, a virus) is found. This is common with infections that are specific to a certain area (like a skin wound infected with bacteria). The virus binds to the cell surface receptors on the macrophage. Remember that different cell types express different receptors. WebCytokines can be major mediators of the pathogenic effect in some diseases, and represent important defense mechanisms in others. Detailed knowledge on the role …

WebTimothy R. La Pine, Harry R. Hill, in Fetal and Neonatal Physiology (Fourth Edition), 2011 Bacterial Lipopolysaccharide. Bacterial LPS is a virulence factor of gram-negative bacteria. It is a powerful cellular activator and promotes cytokine release from neutrophils, macrophages, and other cells of the innate immune response. WebEndotoxins and exotoxins are among the most potent bacterial inducers of cytokines. During infectious processes, the production of inflammatory cytokines including tumor necrosis factor (TNF), interleukin-1β (IL-1β), gamma interferon (IFNγ) and chemokines orchestrates the anti-infectious innate immu …
