Hot off the presses! Work by graduate student Carlos Medina, former post-doc Koshika Yadava and the Bollyky lab is out in the journal eLife today. They report that Tr1 cells, a key regulatory cell type that promotes IL-10-based immune tolerance to potential airway allergens, do not contribute to stable tolerogenic memory. This instability may limit efforts to re-establish tolerance in asthma and other disease by expanding Tr1. Read all about it here. Congratulations!!
