Although KSHV relies on cellular machinery for gene expression, it also uses specialized regulators to control nearly every step of the process. In this review we discuss the current understanding of KSHV gene regulation.Recent findings: High-throughput sequencing and a new robust system to mutate KSHV have paved the way for comprehensive studies of KSHV gene expression, leading to the characterization of new viral factors that control late gene expression and post-transcriptional steps of gene regulation. They have also revealed key aspects of chromatin-based control of gene expression in the latent and lytic cycle.Summary: The combination of mutant analysis and high-throughput sequencing will continue to expand our model of KSHV gene regulation and point to potential new targets for anti-KSHV drugs.","PeriodicalId":45506,"journal":{"name":"Current Clinical Microbiology Reports","volume":"5 4","pages":"219-228"},"PeriodicalIF":5.2,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s40588-018-0102-1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37041543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we provide an introduction to IFITM3 and the biochemical regulation underlying its antiviral activity. Further, we analyze and summarize the published literature examining phenotypes of IFITM3 knockout mice upon infections with viral pathogens and discuss the controversial association between single nucleotide polymorphisms (SNPs) in the human IFITM3 gene and severe virus infections.Recent findings: Recent publications show that IFITM3 knockout mice experience more severe pathologies than wild-type mice in diverse virus infections, including infections with influenza A virus, West Nile virus, Chikungunya virus, Venezuelan equine encephalitis virus, respiratory syncytial virus, and cytomegalovirus. Likewise, numerous studies of humans of Chinese ancestry have associated the IFITM3 SNP rs12252-C with severe influenza virus infections, though examinations of other populations, such as Europeans, in which this SNP is rare, have largely failed to identify an association with severe infections. A second SNP, rs34481144-A, found in the human IFITM3 promoter has also recently been reported to be a risk allele for severe influenza virus infections.Summary: There is significant evidence for a protective role of IFITM3 against virus infections in both mice and humans, though additional work is required to identify the range of pathogens restricted by IFITM3 and the mechanisms by which human SNPs affect IFITM3 levels or functionality.","PeriodicalId":45506,"journal":{"name":"Current Clinical Microbiology Reports","volume":"5 4","pages":"229-237"},"PeriodicalIF":5.2,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6334760/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36870450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet the fungal virulence factors and host factors that modulate CA GI colonization are still poorly understood.

A recent increase in immunocompromised cohorts with solid organ transplants, diabetes mellitus, and other medical conditions have resulted in increased fungal infections including mucormycosis. Our current knowledge about Mucoralean fungi is in its infancy compared to other fungal pathogens, which may be due to lack of robust genetic tools for Mucorales. In this review we summarize recent advances in genetic tools to study the two most prevalent and genetically amenable Mucoralean fungi, Mucor circinelloides and Rhizopus delemar.Recent findings: There have been advances made in the study of Mucorales family genetics. These findings include the construction of recyclable markers to manipulate the genome, as well as silencing vectors, and the adaptation of the CRISPR/Cas9 gene editing system.Summary: We present how these genetic methods have been applied to understand basic biology, morphogenesis, pathogenesis, and host-pathogen interactions in the two Mucoralean fungi, M. circinelloides and R. delemar.

The main focus of this review is to summarize animal studies, which were performed to better understand the cellular and molecular mechanisms underlying the pathology of IRIS.Recent findings: Three IRIS animal models have been reported. They are Mycobacterial IRIS (M-IRIS), cryptococcal IRIS (C-IRIS) and Pneumocystis-IRIS. M-IRIS animal model suggested that, rather than lymphopenia itself, the failure to clear the pathogen by T cells results in excessive priming of the innate immune system. If this happens before T cell reconstitution, hosts likely suffer IRIS upon T cell reconstitution. Interestingly, T cells specific to self-antigens, not only pathogen-specific, could drive IRIS as well.Summary: The mechanism to develop IRIS is quite complicated, including multiple layers of host immune responses; the innate immune system that detects pathogens and prime host immunity, and the adaptive immune system that is reconstituted but hyper-activated particularly through CD4+ T cells. Animal models of IRIS, although there are still small numbers of studies available, have already provided significant insights on the mechanistic understanding of IRIS.","PeriodicalId":45506,"journal":{"name":"Current Clinical Microbiology Reports","volume":"5 3","pages":"201-209"},"PeriodicalIF":5.2,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s40588-018-0099-5","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36776572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
