Microbiology, Virology & Host Pathogen Interaction
An extended DNA-free intranuclear compartment organizes centrosome microtubules in malaria parasitesMalaria arises during the proliferation of Plasmodium spp. in human blood, whereas the underlying atypical cell division mechanisms remain poorly understood. This study uses advanced imaging to dissect dynamics and organization of the centrosome, a key division regulator.
Autoimmune anti-DNA and anti-phosphatidylserine antibodies predict development of severe COVID-19COVID-19 induces high levels of autoimmune anti-DNA and anti-phosphatidylserine antibodies that are detected in some patients upon hospital admission and predict later development of severe disease.
Hepatitis B virus compartmentalization and single-cell differentiation in hepatocellular carcinomaSingle-cell RNA-Seq unravels heterogeneity and compartmentalization of both hepatitis B virus and cancer identifying new candidate pathways for viral hepatocarcinogenesis.
A serum proteome signature to predict mortality in severe COVID-19 patientsA serum proteome panel, which includes several type-3 cystatins and inter-α-trypsin inhibitors, predicts mortality in severe COVID-19 patients very well, in three independent cohorts.
Prognostic accuracy of MALDI-TOF mass spectrometric analysis of plasma in COVID-19High mortality rate in SARS-CoV-2–infected individuals requires accurate markers for predicting COVID-19 severity. MALDI-TOF analysis revealed differential plasma levels of SAA1 and SAA2 associated with higher risk of hospitalization and can be used to improve COVID-19 monitoring and therapy.
Vaccinia virus hijacks ESCRT-mediated multivesicular body formation for virus egressPoxvirus extracellular virions are critical for virus virulence. This study shows that multivesicular bodies serve as a major cellular source of membrane for their formation and spread.
Profiling chromatin accessibility responses in human neutrophils with sensitive pathogen detectionATAC-seq reveals unique neutrophil chromatin architecture changes in response to different stimuli before transcriptional activation, possibly regulating downstream gene expression.
Viperin interacts with PEX19 to mediate peroxisomal augmentation of the innate antiviral responseThis work highlights the multifunctional role of the ISG viperin and its interaction with the peroxisomal protein Pex19 to modulate peroxisomal-dependent innate signaling that ultimately restricts viral infection.
Cell-autonomous Toxoplasma killing program requires Irgm2 but not its microbe vacuolar localizationIrgm2 controls Toxoplasma killing via selective recruitment of Gbp1 and Irgb6 to Toxoplasma parasitophorous vacuoles, whereas its vacuolar localization is dispensable for parasite killing.
Human IFITM3 restricts chikungunya virus and Mayaro virus infection and is susceptible to virus-mediated counteractionEndogenous and heterologpusly expressed human IFITM3 restricts early and late replication steps of chikungunya and Mayaro virus infection and is downregulated at the protein level in infected cells.
