IL4R (Interleukin 4 Receptor): IL4R is the receptor for interleukin 4 (IL4), a cytokine involved in the differentiation of naive T cells into Th2 cells, promoting B cell proliferation, and antibody production. IL4R signaling is critical for the development and regulation of allergic responses, including the production of IgE. Dysregulation of IL4R signaling has been implicated in the pathogenesis of asthma, atopic dermatitis, and other allergic conditions, making it a target for therapeutic intervention....
