Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Alexa Fluor® 647 Anti-CD8 alpha antibody [CAL66] (AB305048)

Immunohistochemical analysis of paraffin-embedded Human tonsil tissue labeling CD8 alpha with ab305048 at 1/100 (5.0 ug/ml). Positive staining on human tonsil. The section was incubated with ab305048 for 60 mins at room temperature (shown in red). Nuclear DNA was labeled with DAPI (shown in blue). The section was then mounted using Fluoromount®.

The immunostaining was performed on a Leica Biosystems BOND RX instrument. Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8). Heat mediated antigen retrieval was performed with Tris-EDTA buffer (pH 9.0, Epitope Retrieval Solution2) for 40 mins.

Negative control : PBS instead of the primary antibody.

CD8 alpha also known as CD8A or CD8 protein is a glycoprotein subunit expressed on the surface of cytotoxic T lymphocytes. It has a mass of approximately 32 kDa. Found on the surface cell membrane CD8 alpha functions primarily in the immune response specifically in the recognition of antigens bound to major histocompatibility complex (MHC) class I molecules. Often scientists use CD8 antibodies for detection and CD8 IHC or immunohistochemistry for localization studies.
Biological function summary

The CD8 alpha protein plays a critical role in T-cell mediated immune responses. It forms a heterodimer with the CD8 beta chain creating the CD8 alpha-beta complex that strengthens T-cell interaction with antigen-presenting cells. CD8 alpha also helps in signaling processes that activate T cells equipping them to destroy infected or malignant cells. Researchers often study CD8 alpha peptides to understand its interactions better.

Pathways

CD8 alpha is integral to the T-cell receptor signaling pathway and the cytotoxic T lymphocyte (CTL) pathway. The T-cell receptor complex which includes the CD8 molecule transmits signals that are important for T-cell activation and function. CD8 interacts with key proteins such as the T-cell receptor (TCR) and MHC class I molecules facilitating targeted responses against pathogens. These pathways highlight CD8 alpha’s role in adaptive immunity.

CD8 alpha is most prominently associated with viral infections and cancer. Conditions like HIV and some forms of leukemia show altered CD8 function highlighting the protein's role in immune surveillance. In HIV infection for instance CD8 T cells reduce in number impairing the immune response. CD8 alpha’s connection to the immune system places it alongside other immune proteins such as CD4 and MHC molecules in the context of immune dysfunction.

타겟 정보

The protein expressed by the gene CD8A is an integral membrane glycoprotein crucial for immune responses, operating mainly in T-cells as a coreceptor for MHC class I molecule : peptide complexes. These peptides originate from cytosolic proteins, unlike class II peptides, which are from extracellular proteins. CD8A interacts with the T-cell receptor (TCR) and MHC class I proteins on antigen-presenting cells, recruiting the Src kinase LCK to the TCR-CD3 complex. LCK phosphorylates substrates, triggering signaling pathways that lead to the production of lymphokines, enhanced motility, adhesion, and activation of cytotoxic T-lymphocytes (CTLs), thereby aiding in the recognition and elimination of infected or tumor cells. Additionally, in natural killer (NK) cells, CD8A homodimers on the cell surface provide a survival mechanism for conjugating with and lysing multiple target cells. CD8A homodimers also facilitate the survival and differentiation of activated lymphocytes into memory CD8 T-cells.
