CD121B, also known as interleukin-1 receptor type 2 (IL1R2), is a key regulatory component of the interleukin-1 (IL-1) signaling pathway. IL-1 is a potent pro-inflammatory cytokine involved in immune responses, inflammation, and tissue homeostasis. Unlike the signaling receptor IL1R1 (CD121A), IL1R2 functions primarily as a decoy receptor. It binds IL-1β and IL-1α with high affinity but lacks an intracellular Toll/IL-1 receptor (TIR) domain required for signal transduction, thereby inhibiting IL-1-mediated inflammatory responses. This regulatory mechanism helps prevent excessive immune activation and tissue damage. IL1R2 exists in both membrane-bound and soluble forms, with the latter generated via proteolytic cleavage or alternative splicing, further enhancing its anti-inflammatory role by sequestering free IL-1 ligands.
CD121B antibodies are critical tools for studying IL-1 pathway modulation, particularly in conditions like autoimmune diseases, sepsis, and chronic inflammation where IL-1 dysregulation is implicated. They enable the detection, quantification, and functional blocking of IL1R2 in experimental models, aiding research into therapeutic strategies targeting IL-1 signaling. Additionally, IL1R2's overexpression in certain cancers has sparked interest in its role in tumor microenvironments and immune evasion. CD121B-specific antibodies thus hold potential for diagnostic and therapeutic applications, including the development of biologics to fine-tune IL-1 activity in inflammatory and neoplastic disorders.
