CD28

CD28, a cell surface glycoprotein receptor, predominantly expressed on activated T cells, belongs to the Ig superfamily and provides a critical co-stimulatory signal. Its ligands, CD80 and CD86, are typically found on the surface of antigen-presenting cells and can either bind CD28 or CTLA-4. CD28 interacts with the CD80 dimer with relatively high affinity and the CD86 monomer with lower affinity, mediating T cell co-stimulation in conjunction with T cell receptor (TCR) signals. CD28 drives critical intracellular biochemical events including unique phosphorylation and transcriptional signaling, metabolism, and the production of key cytokines, chemokines, and survival signals that are essential for long-term expansion and differentiation of T cells. Most importantly, treatment of mice with a soluble CD28 antagonist induced antigen-specific tolerance that prevented the progression of autoimmune diseases and organ graft rejection.

    M04
    M04 is an agonist of STING. It induces the expression of the IFN reporter gene in HEK293T cells expressing wild-type human STING, but does not induce this expression in HEK293T cells expressing the R71H-G230A-R293Q (HAQ) STING variant or in mouse RAW 264.7 cells, indicating that its activity is dependent on allelic and species variations. M04 induces the production of TNF-α, IL-10, IL-1β, and IL-12p70 in human peripheral blood mononuclear cells (PBMCs). At a concentration of 50 µM, M04 stimulates dendritic cells isolated from PBMCs to express the MHC class II cell surface receptor HLA-DR and co-stimulatory molecules CD40, CD80, and CD86, and also enhances their ability to activate T cells in an ex vivo assay. M04 can be used in research on inflammatory immune diseases.
