Immunohistochemical analysis of paraffin-embedded human Colon cancer tissue using CD69 antibody was performed. The section was pretreated using high-temperature and high-pressure mediated EDTA antigen retrieval buffer (pH 9.0), for 5 minutes. The tissues were incubated with primary antibody (HY-P81373,1:100 dilution) at room temperature for 60 minutes. Detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. The tissues were counterstained with hematoxylin and mounted with neutral balsam mounting medium. -

Background
-
Function
CD69 is a transmembrane protein primarily expressed on mucosa-resident T cells, playing a crucial role in immune cell homeostasis. Following activation by various stimuli-such as antigen recognition or cytokine signaling-CD69 is rapidly expressed on the surface of platelets, T lymphocytes, and NK cells, where it activates distinct signaling pathways across different cell types. CD69 negatively regulates Th17 cell differentiation through a carbohydrate-dependent interaction with galectin-1 (LGALS1) present on immature dendritic cells. It also acts via the S100A8/S100A9 complex on peripheral blood monocytes to promote the conversion of naive CD4+ T cells into regulatory T cells. Mechanistically, it specifically recognizes Pseudomonas aeruginosa, promoting ERK1 activation and the subsequent secretion of granulocyte-macrophage colony-stimulating factor (GM-CSF) and other inflammatory cytokines.

Expression
Tissue_specificity:It is expressed on the surface of activated T cells, B cells, natural killer cells, neutrophils, eosinophils, epidermal Langerhans cells, and platelets.
Induction:By antigens, mitogens or activators of PKC on the surface of T and B-lymphocytes. By interaction of IL-2 with the p75 IL-2R on the surface of NK cells -
Subunit
Homodimer; disulfide-linked. Interacts with S100A8 and S100A9. Interacts with galactin-1/LGALS1. Interacts with S1PR1; this interaction mediates S1PR1 degradation
