Recombinant Human CCL27

Chemokine (C-C motif) ligand 27 (CCL27) is a small cytokine belonging to the CC chemokine family. It is associated with homing of memory T lymphocytes to the skin, and plays a role in T cell-mediated inflammation of the skin. CCL27 is expressed in numerous tissues, including gonads, thymus, placenta and skin. It elicits its chemotactic effects by binding to the chemokine receptor CCR10.

CCL27 is one of the CC chemokines produced by epidermal keratinocytes and is suggested to be involved in the pathogenesis of inflammatory skin diseases. CCL27 modifies inflammation by attracting CCR10-positive and CCR4-positive cells into the lesional skin, and may participate in the pathogenesis of Th2-shifted skin diseases such as atopic dermatitis.

The biological activity of Human CTACK was determined by its ability to induce chemotaxis of mouse BaF/3 cells transfected with mCCR10. The expected ED₅₀ for this effect is typically 0.1 - 0.4 μg/ml.
