Cytokines microbe notes
WebAntibodies alone are often not enough to protect the body against pathogens. In these instances, the immune system uses cell-mediated immunity to destroy infected body cells. T cells are responsible for cell-mediated immunity. Killer T cells (cytotoxic T cells) assist with the elimination of infected body cells by releasing toxins into them and ... WebCytokines are a group of low-molecular- weight regulatory proteins secreted by WBC and other cells in the body. 2. Cytokine secretion is very specific and self- limited event as because they are not usually stored as performed molecules. Cytokine synthesis is initiated by new gene transcription as a consequence of cellular activation.

In addition, activation of complement at the site of infection results in production of the chemotactic and proinflammatory C5a. WebCytokines are a broad and loose category of small proteins (~5–25 kDa [1]) important in cell signaling. Cytokines are peptides and cannot cross the lipid bilayer of cells to enter the cytoplasm. Cytokines have been shown to be involved in autocrine, paracrine and endocrine signaling as immunomodulating agents.
