简介
ICOS is a key protein for T cell function and can significantly enhance various T cell responses to foreign antigens. It plays a crucial role in promoting T cell proliferation, lymphokine secretion and upregulation of intercellular interaction molecules, and promoting efficient secretion of B cell antibodies. ICOS Protein, Rat (C137S, C138S, HEK293, His) is the recombinant rat-derived ICOS protein, expressed by HEK293, with C-His labeled tag.

Protein Description
ICOS (Inducible T-cell COStimulator) is a member of the CD28 family of costimulatory molecules pivotal for T-cell activation and immune response regulation. Its role in mediating signals that promote T-cell proliferation, differentiation, and survival has made it a significant focus in immunological research. The ICOS pathway has been implicated in various diseases, particularly autoimmune disorders and cancers, as dysregulation of ICOS signaling can lead to excessive immune responses or inadequate tumor immunity. Consequently, researchers have been exploring ICOS as a therapeutic target. The study of recombinant ICOS proteins involves understanding their structure, function, and interactions with other immune molecules, enabling insights into their pivotal role in immune modulation. Additionally, recombinant ICOS proteins can be used in preclinical models to assess their potential as predictive biomarkers or therapeutic agents. The development of ICOS-targeting therapies, such as monoclonal antibodies or agonists, holds promise for enhancing immune responses in cancer immunotherapy or restoring balance in autoimmune diseases. Therefore, investigating ICOS recombinant proteins is crucial for developing innovative immunotherapeutic strategies that leverage the body's immune system to achieve more effective disease management.
