Chemotaxis Induced by CCL22/MDC and Neutralization by Human CCL22/MDC Antibody. Recombinant Human CCL22/MDC (Catalog # 336-MD) chemoattracts the BaF3 mouse pro-B cell line transfected with human CCR4 in a dose-dependent manner (orange line). The amount of cells that migrated through to the lower chemotaxis chamber was measured by Resazurin (Catalog # AR002). Chemotaxis elicited by Recombinant Human CCL22/MDC (10 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human CCL22/MDC Monoclonal Antibody (Catalog # MAB336). The ND50 is typically 0.6-3.0 µg/mL.

B, Overexpression of p65 significantly reduced the luciferase activity driven by miR‐23a promoter. Mutagenesis in the p65‐binding site released such repression. C, ChIP assay confirmed that p65 could bind to the promoter region of miR‐23a. D, p65 inhibition upregulated miR‐23a level.

Background: CCL22/MDC

CCL22, also named stimulated T cell chemotactic protein (STCP-1) and MDC, is a CC chemokine initially isolated from clones of monocyte-derived macrophages. Human CCL22 cDNA encodes a precursor protein of 93 amino acid residues with a 24 amino acid residue predicted signal peptide that is cleaved to yield a 69 amino acid residue mature 8 kDa protein. At the amino acid sequence level, CCL22 shows less than 35% identity to other CC chemokine family members. Human CCL22 is expressed in dendritic cells, macrophages and activated monocytes. In addition, CCL22 expression is also detected in the tissues of thymus, lymph node and appendix. The gene for human CCL22 has been mapped to chromosome 16 rather than chromosome 17 where the genes for many human CC chemokines are clustered. Recombinant or chemically synthesized mature CCL22 has been shown to induce chemotaxis or Ca2+ mobilization in dendritic cells, IL-2 activated NK cells, and activated T lymphocytes. A CD8+ T lymphocyte-derived secreted soluble activity that suppresses infection by primary non-syncytium-inducing and syncytium-inducing HIV-1 isolates and the T cell line-adapted isolate HIV-1IIIB, has been identified as CCL22. Based on amino-terminal sequence analysis, the major CD8+ T lymphocyte-derived CCL22 protein yielded an amino-terminal sequence of YGANM, which is two amino acid residues shorter than the predicted mature CCL22. The difference in potency between the two mature CCL22 isoforms has not been determined.
