The Immunity article (Vasamsetti and Florentin et al., Immunity 2018) published by the Dutta lab has been highlighted in a UPMC News Release and by United Press International. In this publication, Dutta and his team unexpectedly found that a subset of tyrosine hydroxylase (TH)-positive leukocytes produces high levels of catecholamines, and triggers proliferation and differentiation of myeloid progenitors in diabetic patients. Inflammatory myeloid cells generated from their progenitors increase the risk of atherosclerosis.
