Research topic

Chemokines, Cytokines and chemokines and related molecules


Cutaneous T-cell-attracting chemokine (CTACK)(CCL27) is a ligand for cell surface receptor CCR10. It is responsible for chemotaxis of skin-homing memory T cells during cutaneous inflammation. Interestingly, after CCR10-mediated internalization, CTACK, as well as a non-secreted splice variant of the same gene, can reach the nucleus and modulate transcription and cell behavior.
