CD14 protein as a modulator of the inflammatory response / Bialko CD14 jako modulator odpowiedzi zapalnej.

ABSTRACT

CD14 is one of the key proteins involved in the activation of the inflammatory response of immune cells. CD14 binds bacterial lipopolysaccharide (LPS) and transfers its molecules to the complex of Toll-like receptor 4 (TLR4) and MD-2 protein, which in turn triggers pro-inflammatory signaling pathways necessary to combat infection. CD14 determines the final shape of the pro-inflammatory reaction of cells to LPS, serving as a transporter of this endotoxin and also as a regulator of TLR4 activity. In addition, CD14 transports other molecules of microbial or endogenous origin to their target receptors/proteins, participating in the activation of pro-inflammatory signaling pathways triggered by the presence of pathogens, as well as tissue damage. Currently, more attention is paid to the role of the CD14 protein in the development of non-infectious diseases such as autoimmune diseases, metabolic diseases and cardiovascular diseases.
