This recombinant monoclonal antibody is developed as a research-grade biosimilar to reference antibody TQC2938, targeting IL1RL1 (Interleukin 1 Receptor Like 1), also known as ST2. IL1RL1 functions as a receptor for IL-33 and plays a critical role in type 2 immune responses and inflammatory signaling pathways. Upon IL-33 binding, IL1RL1 activates downstream signaling cascades involving NF-κB and MAP kinases, promoting the production of pro-inflammatory cytokines. This receptor is implicated in various pathological conditions including allergic diseases, asthma, cardiovascular disorders, and fibrotic conditions. Both membrane-bound and soluble forms of IL1RL1 exist, with the soluble form acting as a decoy receptor that modulates IL-33 activity.
As a biosimilar to TQC2938, this antibody provides researchers with a reliable tool for investigating IL1RL1 expression, localization, and function in cellular and disease models. It supports studies examining the IL-33/IL1RL1 axis in immune regulation, inflammatory responses, and potential therapeutic interventions. This antibody enables exploration of IL1RL1's role across diverse research areas including immunology, inflammation biology, and translational medicine.
