Microbiology, Virology & Host Pathogen Interaction
Virus-induced transposable element expression up-regulation in human and mouse host cellsGenome-wide transposon expression up-regulation in host cells regardless of virus, species, and host cell tissue types occurs early during viral infection and likely contributes to promoting the host innate immune response.
A key region of molecular specificity orchestrates unique ephrin-B1 utilization by Cedar virusAn expanded hydrophobic cavity within the structurally constrained receptor-binding site of the Cedar virus attachment glycoprotein facilitates idiosyncratic utilization of ephrin-B1.
Initial phospholipid-dependent Irgb6 targeting to Toxoplasma gondii vacuoles mediates host defenseIrgb6 has a role in the cell-autonomous response against T. gondii and involves ubiquitination and breakdown of vacuoles via binding of a specific phospholipid on the parasitophorous vacuole membrane.
Bat IFITM3 restriction depends on S-palmitoylation and a polymorphic site within the CD225 domainComparative analysis reveals adaptive evolution of bat IFITMs and a naturally polymorphic site within the conserved CD225 domain that affects S-palmitoylation and antiviral function of bat IFITM3.
ADAPTABLE: a comprehensive web platform of antimicrobial peptides tailored to the user’s researchADAPTABLE is a webserver and database of antimicrobial peptides that uses sequence and property alignment to highlight their mode of action against the threat of resistance in medicine and agriculture.
Pseudomonas aeruginosa lectin LecB impairs keratinocyte fitness by abrogating growth factor signallingThis study provides a novel function of the bacterial lectin LecB, which dampens cell proliferation and survival by targeting the insulin-like growth factor-1 for degradation, without receptor activation.
Thymosin β4 promotes autophagy and repair via HIF-1α stabilization in chronic granulomatous diseaseThis study demonstrates that thymosin β4 stabilizes HIF-1a to promote autophagy and up-regulate genes involved in tissue and mucosal barrier protection in chronic granulomatous disease.
Conservation of cell-intrinsic immune responses in diverse nonhuman primate speciesThe transcriptomic response of diverse nonhuman primate (NHP) species to poly(I:C) is highly conserved, and this novel RNA sequencing dataset will help improve NHP genome annotations.
XIAP controls RIPK2 signaling by preventing its deposition in speck-like structuresThis study provides evidence that the NOD1/2-associated kinase RIPK2 localizes to detergent insoluble cytosolic complexes upon activation and suggests novel regulatory mechanisms for RIPK2 signaling.
Assembly mechanisms of the bacterial cytoskeletal protein FilPFilP is a coiled-coil protein that self-assembles into striated filaments and meshwork that shares structural and biochemical characteristics with metazoan intermediate filaments.
