General description

Macrophage-derived chemokine (MDC) is also known as C-C motif chemokine ligand 22 (CCL22). It is a CC chemokine that is produced in B cells, macrophages, monocyte-derived dendritic cells, activated natural killer (NK) cells and cluster of differentiation 4 (CD4) T cells. The gene encoding it is localized on human chromosome 16. Recombinant human MDC is an 8.0kDa protein containing 67 amino acid residues including the four highly conserved cysteine residues present in the CC chemokines.

Biochem/physiol Actions

Macrophage-derived chemokine (MDC) signals through the C-C chemokine receptor type 4 (CCR4). It chemo-attracts monocytes, dendritic cells and natural killer (NK) cells and aids in their function. The protein exerts human immunodeficiency virus (HIV) suppressive activity. The 67 amino acid form of MDC displays reduced chemoattractant activity but retains HIV suppressive activity. It is expressed in various cancers and is involved in recruitment of regulatory T cells (Treg) within a tumor.

Physical form

Lyophilized with no additives.

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.

Posttranslational processing of chemokines increases (IL-8) or decreases (monocyte chemotactic protein-1) their chemotactic potency. Macrophage-derived chemokine (MDC) attracts monocytes, dendritic cells, activated lymphocytes, and NK cells and has reportedly anti-HIV-1 activity. Here we report that truncation of MDC by deletion
