Description

CCL22 is thymus-specific chemokine engaged in the recruitment of T cells. CCL22 is associated with different diseases such as allergen-induced lung inflammation, atopic dermatitis, and lymphoma. Also, high levels of CCL22 have been detected in the CNS in multiple sclerosis (MS) and experimental autoimmune encephalomyelitis (EAE). In addition, CCR4+ T cells have been linked to endotoxic shock, rheumatoid arthritis, T cell lymphoma, and autoimmune diabetes. CCL22 is a prostaglandin-dependent pyrogen, acting in the anterior hypothalamus to induce hyperthermia via activation of brown adipose tissue.

Structure
Chemokine
Distribution

Macrophages, NK cells, IFN-γ stimulated human keratinocytes, thymic epithelial cells, and intestinal epithelial cells

Function
CCL22 induces the migration of CCR4+ Th2 cells, Tregs, DC, and NK cells. It is induced by LPS and CD40 antibody in macrophages. It is upregulated by Th2 cytokines (IL-4 and IL-5) and downregulated by Th1 cytokines (IFN-γ).
Interaction
Dendritic cells, NK cells, Th2 cells, T regs, CLA+ skin-homing memory/effector T cells
Ligand/Receptor
CCR4

Related FAQs

Do you guarantee that your antibodies are totally pathogen free?

BioLegend does not test for pathogens in-house aside from the GoInVivo™ product line. However, upon request, this can be tested on a custom basis with an outside, independent laboratory.

Does BioLegend test each Ultra-LEAF™ antibody by functional assay?

No, BioLegend does not test Ultra-LEAF™ antibodies by functional assays unless otherwise indicated. Due to the possible complexities and variations of uses of biofunctional antibodies in different assays and because of the large product portfolio, BioLegend does not currently perform functional assays as a routine QC for the antibodies. However, we do provide references in which the antibodies were used for functional assays and we do perform QC to verify the specificity and quality of the antibody based on our strict specification criteria.

Does BioLegend test each Ultra-LEAF™ antibody for potential pathogens?

No, BioLegend does not test for pathogens in-house unless otherwise indicated.  However, we can recommend an outside vendor to perform this testing as needed.

Have you tested this Ultra-LEAF™ antibody for in vivo or in vitro applications?

We don't test our antibodies for in vivo or in vitro applications unless otherwise indicated. Depending on the product, the TDS may describe literature supporting usage of a particular product for bioassay. It may be best to further consult the literature to find clone specific information.
