      Non-Redundant Roles of Topoisomerase 2α and 2β in the Cytosolic Replication of Vaccinia Virus - 2 month(s) ago

      Vaccinia virus is a large enveloped DNA virus, which, like all poxviruses, replicates in the cytoplasm of infected cells. Vaccinia was historically thought to encode all the proteins required for its replication. However, recent findings have shown that nuclear host proteins are redirected to the cytoplasm to facilitate viral replication. Among these, topoisomerase 2α (TOP2A) and 2β (TOP2B), which mediate nuclear transcription, DNA replication, and chromosome segregation are the most abundant host proteins associated with nascent viral genomes. Here, we investigate the mechanisms driving TOP2A and TOP2B cytoplasmic translocation and their role in viral replication. We found that early viral protein synthesis induces the cytosolic relocalization of both isoforms, which are subsequently recruited to viral factories by an interaction of their C-terminal domains with the viral ligase, A50. TOP2A promotes replication by interacting with the vaccinia DNA replication machinery. In contrast, T

      Chlamydia trachomatis impairs T cell priming by inducing dendritic cell death | Infection and Immunity - 6 month(s) ago

      Chlamydia trachomatis is an obligate intracellular bacterium that infects epithelial cells. It is the most common bacterial sexually transmitted disease in the United States, with an estimated 2.86 million infections occurring annually (1). While curable with antibiotics, infections are often asymptomatic and thus left untreated (2). This can lead to serious sequelae in women, such as pelvic inflammatory disease, infertility, and ectopic pregnancy (3). Despite the high public health burden of C. trachomatis, a vaccine to prevent this disease is not available. A better understanding of the immune response to C. trachomatis is, therefore, crucial to the development of an effective vaccine (4).
