Flow cytometry staining of C57 BL/6 mouse thymocytes with ab313760 (right) or Rabbit IgG (monoclonal) Phycoerythrin (ab209478) (left). C57 BL/6 mouse thymocytes were incubated for 30 min on ice in 1x PBS containing 10 μg/ml anti CD16/CD32 and 10% normal goat serum to block FC receptors and non-specific protein-protein interaction followed by the antibody ab313760 or Rabbit IgG (monoclonal) Phycoerythrin (ab209478) (1x 106 in 100 μl at 0.2 μg/ml (1/2500)) for 30 min on ice. The cells were simultaneously stained with CD4.

Acquisition of >30000 events were collected using a 50 mW Yellow/Green laser (561nm) and 585/42 bandpass filter.

Events were gated on viable cells.

Supplementary information

CD8 also known as CD8a or Leu-2 is a glycoprotein with a molecular weight of approximately 32 kDa. It is prominently expressed on the surface of cytotoxic T lymphocytes. These CD8 molecules facilitate the interaction between T cells and antigen-presenting cells by binding to major histocompatibility complex (MHC) class I molecules. This interaction is essential for the immune system to recognize and destroy infected or cancerous cells. CD8 is often identified using various markers like CD8 FITC CD8 APC and CD8 PerCP which are used in flow cytometry for cell sorting and analysis.
Biological function summary

CD8 plays a significant role in the adaptive immune response. It is not part of a multimeric complex but functions as a co-receptor that enhances the recognition of antigens by the T cell receptor (TCR). The presence of CD8 molecules aids the activation of T cells leading to their proliferation and the effective targeting and elimination of pathogens or abnormal cells. The ability of CD8 to bind to MHC class I molecules allows cytotoxic T cells to detect and respond to nearly all nucleated cells in the body.

Pathways

CD8 is integral in both the T cell receptor signaling pathway and the induction of apoptosis. In the T cell receptor signaling pathway CD8 works closely with other proteins like Lck and ZAP-70 to transmit signals upon TCR-MHC class I engagement. This promotes T cell activation cytokine production and cell division. Furthermore CD8's interaction with Fas ligand pathways contributes to the initiation of programmed cell death which is important for maintaining immune homeostasis and preventing overreaction of the immune system.

CD8 T cells are significant in the context of viral infections and autoimmune diseases. For example during HIV infection the depletion of CD8 T cells impairs the immune response allowing the virus to evade the immune system. Additionally in autoimmune disorders like Type 1 diabetes CD8 T cells mistakenly target and destroy insulin-producing beta cells in the pancreas. These pathological processes also involve proteins such as MHC class I and other immune modulators like interleukins that modulate CD8 T cell activity and differentiation.

Target data

Integral membrane glycoprotein that plays an essential role in the immune response and serves multiple functions in responses against both external and internal offenses. In T-cells, functions primarily as a coreceptor for MHC class I molecule : peptide complex. The antigens presented by class I peptides are derived from cytosolic proteins while class II derived from extracellular proteins. Interacts simultaneously with the T-cell receptor (TCR) and the MHC class I proteins presented by antigen presenting cells (APCs). In turn, recruits the Src kinase LCK to the vicinity of the TCR-CD3 complex. A palmitoylation site in the cytoplasmic tail of CD8B chain contributes to partitioning of CD8 into the plasma membrane lipid rafts where signaling proteins are enriched. Once LCK recruited, it initiates different intracellular signaling pathways by phosphorylating various substrates ultimately leading to lymphokine production, motility, adhesion and activation of cytotoxic T-lymphocytes (CTLs). Additionally, plays a critical role in thymic selection of CD8+ T-cells.
