ZFAND6 promotes TRAF2-dependent mitophagy to restrain cGAS-STING signaling.

ZFAND6 is a zinc finger protein that interacts with TNF receptor-associated factor 2 (TRAF2) and polyubiquitin chains and has been linked to tumor necrosis factor (TNF) signaling. Here, we report a previously undescribed function of ZFAND6 in maintaining mitochondrial homeostasis by promoting mitophagy. Deletion of ZFAND6 in bone marrow-derived macrophages (BMDMs) upregulates reactive oxygen species (ROS) and the accumulation of damaged mitochondria due to impaired mitophagy.

Human neural progenitor cell models to study the antiviral effects and neuroprotective potential of approved and investigational human cytomegalovirus inhibitors.

Human cytomegalovirus (HCMV) is the viral leading cause of congenital defects in newborns worldwide. Many aspects of congenital CMV (cCMV) infection, which currently lacks a specific treatment, as well as the main determinants of neuropathogenesis in the developing brain during HCMV infection are unclear. In this study, we modeled HCMV infection at different stages of neural development.

Genomic Markers Associated with Cytomegalovirus DNAemia in Kidney Transplant Recipients.

Human cytomegalovirus (CMV) is a major pathogen after solid organ transplantation, leading to high morbidity and mortality. Transplantation from a CMV-seropositive donor to a CMV-seronegative recipient (D+/R-) is associated with high risk of CMV disease. However, that risk is not uniform, suggesting a role for host factors in immune control of CMV.

Harnessing the Noncanonical Keap1-Nrf2 Pathway for Human Cytomegalovirus Control.

Host-derived cellular pathways can provide an unfavorable environment for virus replication. These pathways have been a subject of interest for herpesviruses, including the betaherpesvirus human cytomegalovirus (HCMV). Here, we demonstrate that a compound, ARP101, induces the noncanonical sequestosome 1 (SQSTM1)/p62-Keap1-Nrf2 pathway for HCMV suppression.
