Immunopharmacology Comments
Compound 31 was designed to examine the potential of small molecule CCR4 antagonists as immuno-oncology drugs. It was found to reduce trafficking of Treg cells to the tumour microenvironment but did not inhibit their migration to the spleen, which suggests that compound 31 may not disrupt crucial immune functions of Treg in healthy, non-target tissues [1].
