Mycolactone impairs T cell homing by suppressing microRNA control of L-selectin expression

Abstract excerpt

Mycolactone is a macrolide produced by Mycobacterium ulcerans with immunomodulatory properties. Here, we describe that in mouse, mycolactone injection led to a massive T-cell depletion in peripheral lymph nodes (PLNs) that was associated with defective expression of L-selectin (CD62-L). Importantly, preexposure to mycolactone impaired the capacity of T cells to reach PLNs after adoptive transfer, respond to...
