Background

CD40 is a type I membrane glycoprotein that is expressed on various antigen-presenting cells (APCs), such as B cells, macrophages, and dendritic cells. The binding of CD40 and CD28 to their respective ligands provides co-stimulatory signals that activate T cells. Anti-CD28 and CD40 bispecific antibodies (BsAbs) recognize T cells with one arm, and APCs with the other. This strategy mitigates the T cell receptor (TCR) dependent activation threshold for T cells, resulting in enhanced proliferation, cytokine production, and cell survivability. These BsAbs have potential in research on diseases, such as Rheumatoid arthritis and Type 1 diabetes (T1D).
