Any process that activates or increases the frequency, rate or extent of type I hypersensitivity, a type of inflammatory response. An acute inflammatory response to an antigenic stimulus. An acute inflammatory response occurs within a matter of minutes or hours, and either resolves within a few days or becomes a chronic inflammatory response. Any process involved with the carrying out of an immune response by a B cell, through, for instance, the production of antibodies or cytokines, or antigen presentation to T cells. Any process that modulates the frequency, rate, or extent of type I hypersensitivity, a type of inflammatory response. Any process that stops, prevents, or reduces the rate of type I hypersensitivity, a type of inflammatory response. An immune response mediated by immunoglobulins, whether cell-bound or in solution. An inflammatory response to an exogenous environmental antigen or an endogenous antigen initiated by the adaptive immune system. An inflammatory response driven by antigen recognition by antibodies bound to Fc receptors on mast cells, occurring within minutes after exposure of a sensitized individual to the antigen, and leading to the release of a variety of inflammatory mediators such as histamines. An inflammatory response driven by antigen recognition by antibodies bound to Fc receptors basophils, occurring within minutes after exposure of a sensitized individual to the antigen, and leading to the release of a variety of inflammatory mediators such as histamines. An inflammatory response driven by antigen recognition by antibodies bound to Fc receptors on mast cells or basophils, occurring within minutes after exposure of a sensitized individual to the antigen, and leading to the release of a variety of inflammatory mediators such as histamines.
