What is Immune IgE receptor on mast cell in response to parasite involve mechanism of and explain in detail?
(B) Opioid # Mast cells have a number of on their cell surface. They express the high effinity surface receptor for the Fc portion of the IgE molecule (Fc&RI).> Antigenic specific binding allows for cross-linking og IgE molecules that have bound to Fc & RI on the mast cell surface.> This initiates a sequence of calcium & energy dependent events that culminate in fusion of granules to the plasma membrane, eventuating in release of the granule contents.> Degranulation & release of potent prostinoids, histamines, & inflammatory cytokines can rapidly recruit inflammatory cells.> Mast cells also express Opioid, Adenosine & beta-adrenergic receptors, &, as a result mast cell stimulation can proceed through actions independent of Fc&RI.> Non antigenic stimuli include Opiates, C5a Anaphylatoxin, Stem cell factor & Substance P.
