IL21R

The gene IL21R encodes the protein Interleukin 21 Receptor, also known as IL-21R. This receptor is a crucial component of the IL-21 signaling pathway, which plays a pivotal role in regulating immune responses. IL-21R is expressed on various immune cells, including B cells, T cells, and NK cells, and its interaction with IL-21 promotes cell proliferation, differentiation, and cytokine production. The IL-21R pathway is involved in several immune processes, such as B cell activation, T cell differentiation, and antibody class switching. Dysregulation of this pathway has been linked to various diseases, including autoimmune disorders, such as systemic lupus erythematosus and rheumatoid arthritis, and cancer. Targeting IL-21R has emerged as a potential therapeutic strategy for these conditions, with ongoing research focusing on developing inhibitors and modulators of the IL-21R pathway to treat these diseases.
