<prompt> Immune IgE receptor on mast cell in response to parasite involve mechanism ofCocaineOpioidCannabisAll of the above  <response>: 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 FcRI. 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 FcRI. Non antigenic stimuli include Opiates, C5a Anaphylatoxin, Stem cell factor Substance P.
