In response to a recently published article by Messal et al. (2011) in which the authors show that PD-L2 is expressed by activated T cells and ligation results in suppression of T cell proliferation and cytokine secretion, we here report that PD-L2 is differentially expressed by the diverse Th subsets, with predominant expression by Th2 cells.
