Flow cytometric analysis of Human CD4 expression on human peripheral blood Leukocytes. Human peripheral blood Leukocytes were stained with Brilliant Violet 421™ Mouse Anti-Human CD3 Antibody and either Alexa Fluor® 488 Mouse IgG1 Isotype Control (Left panel) or SDT Alexa Fluor® 488 Mouse Anti-Human CD4 Antibody (Right panel) at 5 μl/test. Flow cytometry and data analysis were performed using BD FACSymphony™ A1 and FlowJo™ software.

Background
CD4 is a glycoprotein found on the surface of certain immune cells, such as helper T cells, monocytes, macrophages, and dendritic cells. It is a monomeric type I transmembrane molecule composed of four immunoglobulin-like domains (D1 to D4) and encoded by a single gene. As a co-receptor for the T-cell receptor (TCR), CD4 plays a crucial role in the immune response by binding to the MHC class II molecules on antigen-presenting cells, which helps T cells recognize and respond to foreign antigens. The interaction between CD4 and MHC class II molecules also activates downstream signaling pathways, leading to the activation of transcription factors and promoting T cell activation. Additionally, CD4 is significant in HIV infection, as the virus binds to CD4 to enter host cells.
