T-Cell Surface Glycoprotein CD4 (CD4) Antibody

Background

The CD4 molecule is a glycoprotein expressed on the surface of immune cells such as T helper cells, monocytes, macrophages, and dendritic cells. CD4 plays a pivotal role in the immune system by aiding in the recognition of antigens and facilitating the immune response. It was identified as a critical component in the adaptive immune system, particularly in the context of T cell function and HIV infection, where it serves as a primary receptor for the virus.
