Rcan1 negatively regulates FcεRI-mediated signaling and mast cell function
Aggregation of the high affinity IgE receptor (Fc epsilonRI) activates a cascade of signaling events leading to mast cell activation. Subsequently, inhibitory signals are engaged for turning off activating signals. We identified that regulator of calcineurin (Rcan) 1 serves as a negative regulator for turning off Fc epsilonRI-mediated mast cell activation. Fc epsilonRI-induced Rcan1 expression ...
متن کاملTim-3 enhances FcεRI-proximal signaling to modulate mast cell activation
T cell (or transmembrane) immunoglobulin and mucin domain protein 3 (Tim-3) has attracted significant attention as a novel immune checkpoint receptor (ICR) on chronically stimulated, often dysfunctional, T cells. Antibodies to Tim-3 can enhance antiviral and antitumor immune responses. Tim-3 is also constitutively expressed by mast cells, NK cells and specific subsets of macrophages and dendrit...
متن کاملTespa1 negatively regulates FcεRI-mediated signaling and the mast cell–mediated allergic response
Antigen-mediated cross-linking of IgE on mast cells triggers a signaling cascade that results in their degranulation and proinflammatory cytokine production, which are key effectors in allergic reactions. We show that the activation of mast cells is negatively regulated by the newly identified adaptor protein Tespa1. Loss of Tespa1 in mouse mast cells led to hyper-responsiveness to stimulation ...
متن کاملDOCK5 functions as a key signaling adaptor that links FcεRI signals to microtubule dynamics during mast cell degranulation
Mast cells play a key role in the induction of anaphylaxis, a life-threatening IgE-dependent allergic reaction, by secreting chemical mediators that are stored in secretory granules. Degranulation of mast cells is triggered by aggregation of the high-affinity IgE receptor, FcεRI, and involves dynamic rearrangement of microtubules. Although much is known about proximal signals downstream of FcεR...
متن کاملMast Cells Produce Interleukin-25 upon FcεRI-mediated Activation
Interleukin (IL)-25 is a recently described T helper 2 (Th2) cell-derived cytokine that belongs to IL-17 family and induces the production of IL-4, IL-5, and IL-13 from an unidentified non-T cell population. Here, we show that mast cells are also potent IL-25-producing cells. When bone marrow-derived mast cells (BMMCs) were stimulated by IgE cross-linking, IL-25 mRNA was induced within 30 min i...
