简介
B7-H2/ICOSLG Protein, a ligand for T-cell receptor ICOS, critically costimulates T-cell proliferation and cytokine secretion. It induces B-cell proliferation and supports plasma cell differentiation, playing a key role in local tissue responses to inflammation. B7-H2/ICOSLG also modulates the secondary immune response by co-stimulating memory T-cell function. In molecular interactions, it has been observed to interact with CTLA4 in vitro. B7-H2/ICOSLG Protein, Human (HEK293, His-Avi) is the recombinant human-derived B7-H2/ICOSLG protein, expressed by HEK293 , with C-Avi, C-His labeled tag.

Protein Description
B7-H2 (also known as ICOSLG) is a crucial co-stimulatory molecule involved in immune regulation, particularly in the activation and differentiation of T cells. It interacts with the Inducible T-cell Co-stimulator (ICOS), which is predominantly expressed on activated T cells. This interaction plays a significant role in enhancing T cell responses, including cytokine production and promoting immunological memory. Understanding the B7-H2/ICOSLG pathway has garnered attention due to its implications in various disease contexts, including chronic infections, autoimmune disorders, and cancer. The expression levels and functional activity of B7-H2 can influence the efficacy of immune responses, making it a potential target for therapeutic intervention. Researchers have sought to develop recombinant B7-H2 proteins to study their biological functions, enhance our understanding of T cell regulation, and explore their potential use in immunotherapy. By generating soluble or fusion forms of this protein, scientists aim to elucidate its signaling mechanisms and interactions with other immune checkpoints. Additionally, the study of B7-H2/ICOSLG may offer new avenues for enhancing vaccine responses or overcoming immune evasion by tumors, providing meaningful insights into the design of novel immunotherapeutic strategies. Overall, the investigation of B7-H2/ICOSLG recombinant proteins has the potential to contribute to the development of innovative treatments for various immune-mediated conditions and to advance our understanding of T cell biology.
