Product Name | Rhesus ICOS Protein, hFc Tag, Avi Tag |
Product Description | The Rhesus ICOS Protein(KMP4334) is produced in HEK293 Cells. A DNA sequence encoding the Rhesus ICOS (NP_001253918.1) (Met1-Lys140) is expressed with a C-terminal Fc region of human IgG1 tag followed by an Avi tag. The expressed protein is biotinylated in vivo by the Biotin-Protein ligase (BirA enzyme) which is co-expressed. |

Background | Inducible costimulator (ICOS), also called AILIM (Activation-Inducible Lymphocyte Immunomediatory Molecule) is a cell-surface receptor and belongs to the CD28 family of immune costimulatory receptors consisting of CD28, CTLA-4, and PD-1. The interaction of B7-H2/ICOS plays a critical role in Th cell differentiation, T−B cell interactions which are essential for the germinal center formation, and humoral immune responses, and as well as the production of cytokine IL-4. Also, ICOS is more potent in the induction of IL-10 production, a cytokine important for the suppressive function of T regulatory cells. The B7-1/B7-2--CD28/CTLA-4 and ICOS-B7RP-1 pathway provide key second signals that can regulate the activation, inhibition, and fine-tuning of T-lymphocyte responses. ICOS stimulates both Th1 and Th2 cytokine production but may have a preferential role in Th2 cell development. Moreover, The B7-1/B7-2-CD28/CTLA-4 and ICOS-B7RP-1 pathway has been suggested as being involved in the development of airway inflammation and airway hyperresponsiveness. |
