PG - 1699-1701 LID - S1074-7613(23)00326-6 [pii] LID - 10.1016/j.immuni.2023.07.013 [doi] AB - Dendritic cells (DCs) are relatively short lived, yet DC frequencies in lymph nodes are stable. In this issue of Immunity, Ugur et al. reveal that type 1 conventional DCs (cDC1s) are maintained in the deep paracortex of the lymph node from a supply of preDCs that proliferate in nearby medullary vessels. Transition from preDC to cDC1 is regulated by Flt3L sensing. CI - Copyright (c) 2023 Elsevier Inc. All rights reserved.
