Flow cytometric analysis of Human CD8 expression on human peripheral blood lymphocytes. Human peripheral blood lymphocytes were stained with Brilliant Violet 421™ Mouse Anti-Human CD3 antibody and either Alexa Fluor® 647 Mouse IgG1 Isotype Control (Left panel) or SDT Alexa Fluor® 647 Mouse Anti- Human CD8 antibody (Right panel) at 1.25 μl/test. Flow cytometry and data analysis were performed using BD FACSymphony™ A1 and FlowJo™ software.

Background
CD8α is a crucial immune glycoprotein that plays a vital role in the immune response by serving as a co-receptor for the T-cell receptor (TCR) on cytotoxic T cells. It forms either a homodimer (α/α) or a heterodimer with CD8β (α/β) to interact with MHC class I molecules on antigen-presenting cells (APCs), facilitating the recognition of intracellular pathogens such as viruses. CD8α also recruits the LCK kinase, which initiates downstream signaling pathways essential for T-cell activation and proliferation. This molecule is critical for the function of cytotoxic T lymphocytes (CTLs) and is involved in various immune-related diseases, including immunodeficiencies and autoimmune conditions.
