In this study, theoretical and experimental approaches were used to monitor the interactions of PAD4 and LFD1. CLusPro server and Dimplot software were used to predict the interaction of these domains. Results, revealed interactive sites between PAD4 and LFD1 on loop regions of both C and N terminal of PAD4. In experimental methods, PAD4 and LFD1 were expressed in Escherichia coli and purified for usage in Magnetic Bead (MB) and Multi-Walled Carbon Nanotubes (MWCNTs) based bio-sensing platforms. In the magnetic-based system, the magnetic sedimentation of QD-PAD4 by MBs-LFD1 and the observation of the fluorescence spectrum ...

ellecchia Processing of certain viral proteins and bacterial toxins by host serine proteases is a frequent and critical step in virulence. The coronavirus spike glycoprotein contains three (S1, S2, and S2′) cleavage sites that are processed by human host proteases. The exact nature of these cleavage sites, and their respective processing proteases, can determine whether the virus can cross species and the level of pathogenicity. Recent comparisons of the genomes of the highly pathogenic SARS-CoV2 and MERS-CoV, with less pathogenic strains (e.g., Bat-RaTG13, the bat homologue of SARS-CoV2) identified possible ...

I live-tweeted a fascinating and perhaps rather depressing meeting with William Haseltine via a Reuters Newsmaker Broadcast. His talk was upbeat but the message does not offer a positive outlook unless we can collaborate internationally to identify, trace, and isolate and go back to early antivirals to treat people urgently. A vaccine will probably never be found, we must stay on top of this virus when we get communities under control. Moreover, we must recognise that another emergent pathogen could appear any time. These are essentially my notes from Haseltines’s talk. Might we ever achieve herd immunity? There is n...

In this study, we investigate the rapid and striking priming-independent LT-induced release of IL-1β in mice within hours of toxin challenge. We find IL-1β release to be a NLRP1b- and caspase-1-dependent, NLRP3 and caspase-11-independent event that requires both neutrophils and peptidyl arginine deiminiase-4 (PAD4) activity. The simultaneous LT-induced IL-18 response is neutrophil-independent. Bone marrow reconstitution experiments in mice show toxin-induced IL-1β originates from hematopoietic cells. LT treatment of neutrophils in vitro did not induce IL-1β, neutrophil extracellular traps (NETs), o...

FG Abstract Capillary morphogenesis gene 2 (CMG2/ANTXR2) is a cell surface receptor for both collagen VI and anthrax toxin. Biallelic loss-of-function mutations in CMG2 lead to a severe condition, hyaline fibromatosis syndrome (HFS). We have here dissected a network of dynamic interactions between CMG2 and various actin interactors and regulators, describing a different behavior from other extracellular matrix receptors. CMG2 binds talin, and thereby the actin cytoskeleton, only in its ligand-free state. Extracellular ligand binding leads to src-dependent talin release and recruitment of the actin cytoskeleton re...

Here’s betting you wouldn’t want anyone blowing smallpox scabs up your nose. But you might feel differently if you lived in 15th century China. Long ago, the Chinese recognized that people who had contracted smallpox once were immune to reinfection. They came up with the idea of preserving scabs from individuals who had suffered mild cases, drying them out, crushing them to a powder and blowing them up the nostril. For boys it was the right nostril, for girls it was the left because, well, 15th century. That is how the story of vaccines usually begins, though that version is decidedly incomplete. For one thing,...

KleeBacillus cereus biovaranthracis (Bcbva) is an untypical anthrax-causing pathogen responsible for high wildlife mortality in Ta ï National Park (TNP), Côte d’Ivoire. However, nothing is known about its effect on the rural population living in the region bordering TNP. Contact to bushmeat is a known risk factor for exposure to a variety of zoonotic pathogens, but no human infections withBcbva were noted so far. Therefor...
