PG - 99-109 LID - S0882-4010(16)30584-8 [pii] LID - 10.1016/j.micpath.2017.05.037 [doi] AB - Dendritic cells (DCs) are effector cells linking the innate immune system with the adaptive immune response. Many viruses eliminate DCs to prevent host response, induce immunosuppression and to maintain chronic infection. In this study, we examined apoptotic response of dendritic cells during in vitro and in vivo infection with ectromelia virus (ECTV), the causative agent of mousepox. ECTV-infected bone marrow dendritic cells (BMDCs) from BALB/c mice underwent apoptosis through mitochondrial pathway at 48 h post infection, up-regulated FasL and decreased expression of anti-apoptotic Bcl-2 and pro-apoptotic Fas. Similar pattern of Bcl-2, Fas and FasL expression was observed for DCs early during in vivo infection of BALB/c mice. Both BMDCs and DCs from BALB/c mice showed no maturation upon ECTV infection. We conclude that ECTV-infected DCs from BALB/c mouse strain help the virus to spread and to maintain infection. CI - Copyright (c) 2017 Elsevier Ltd. All rights reserved.
