Recombinant human CCL4 (Black Circles, Cat. No. 554706) induces the chemotaxis of mouse Baf3-hCCR5 transfectants chemoattractant cells. Anti-human CCL4 antibody (clone W15138B, Purple Squares) neutralizes the chemotaxis of recombinant human CCL4 in Baf3-hCCR5 cells in a dose-dependent manner while the isotype control (Grey Triangles, Cat. No. 400562) does not have the effect. ND50 range: 3 - 30 ng/mL.

CCL4 is an important proinflammatory cytokine involved in acute and chronic inflammatory responses. CCL4 attracts monocytes, NK cells, dendritic cells, and lymphocytes to sites of injury and inflammation. CCL4 signals through the G-protein-coupled receptor CCR5, and since CCR5 is a major co-receptor for M-tropic HIV strains, the anti-HIV effect of CCL4 has been explored. Thus, binding of CCL4 to CCR5 inhibits HIV entry and reduces the cell surface expression of CCR5. CCL4 has been identified as one of the major HIV-suppressive factors produced by CD8+ T cells. CCL4 also protects against type I diabetes by suppressing islet beta-cell inflammatory responses. In a rat model of experimental autoimmune encephalomyelitis, anti-CCL4 treatment using a neutralizing antibody significantly delayed the development, and shortened the duration, of the disease. Activated human peripheral lymphocytes secrete a truncated form of CCL4 that lacks the first two amino acids. CCR5 and truncated CCL4 bind to CCR1 and CCR2. Like CCL3, CCL4 is highly acidic and can form high-molecular weight polymers. Consistent with this observation, CCL4 is secreted as high molecular weight aggregates from HIV-I specific cytotoxic T lymphocytes. The polymerization of CCL4 is reversible and is important for in vivo activity. Heterodimers of CCL3 and CCL4 have also been described.

- Structure
- Chemokine
- Distribution
-
CCL4 is secreted by many mature hematopoietic cells including macrophages, T and B lymphocytes, neutrophils, dendritic cells, mast cells and NK cells. Influenza virus-infected bronchial and nasal epithelial cells produce CCL4.
- Function
- CCL4 attracts monocytes, NK cells, dendritic cells, and T cells. CCL4 acts as an HIV-suppressive factor. Activating transcription factor 3 (ATF3) limits the amount of CCL4 released by macrophages. IFN-γ and NOS2 repress CCL3 and CCL4 in mouse macrophages via ATF3.

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.
