Scientists apply optical pooled CRISPR screening to identify potential new Ebola drug targets

Broad Institute

Murphy New treatments are sorely needed for Ebola virus infections, which cause rare, yet severe, outbreaks. Related news Imaging combined with genetic screening of cells enhances genomic discoveries Although outbreaks of Ebola virus are rare, the disease is severe and often fatal, with few treatment options.

A Visual Guide to Genome Editors

Codon

The core of the CRISPR immune response is a guide RNA (gRNA) that binds to a CRISPR-associated (Cas) protein. If the same virus invades the cell a second time, the gRNA’s spacer sequence will bind to the matching viral DNA sequence, then be cut by the Cas protein. Visit our website to get a copy.

Levers for Biological Progress

Codon

” Nobody really knows without trying it out in the laboratory. Scientists are already building a model that can, for example, look at which RNA molecules are expressed in a cell at t=0 and predict how those molecules will change at t=1. But these models will become increasingly sophisticated over time. There are a few reasons.

Discovery and development of COVID?19 vaccine from laboratory to clinic

Chemical Biology and Drug Design

WHO proclaimed the outbreak of the Ebola virus disease (EVD), in 2014 that killed hundreds of people in West Africa. The development of vaccines for SARS-CoV-2 becomes more difficult due to the viral mutation in its non-structural proteins (NSPs) especially NSP2 and NSP3, S protein, and RNA-dependent RNA polymerase (RdRp).

Evolved prime editors are smaller and more efficient for therapeutic applications

Broad Institute

Now researchers at the Broad Institute of MIT and Harvard have used cutting-edge continuous laboratory evolution and engineering methods to develop improved versions of the gene-editing tool. Reverse transcriptase proteins that copy RNA templates into strands of DNA are found naturally in all plant and animal cells and in many viruses.

Phages could help to tackle antimicrobial resistance

Drug Target Review

Researchers from the Laboratory of Bacteriology at The Rockefeller University have now found that bacteria sense phages by a defensive response named CBASS (cyclic oligonucleotide-based antiphage signalling system) which detects viral RNA. The novel, hairpin-shaped molecule was named cabRNA for CBASS-activating bacteriophage RNA.
