Researchers engineer in vivo delivery system for prime editing, partially restoring vision in mice

Broad Institute

In the new work published today in Nature Biotechnology , the team adapted engineered virus-like particles (eVLPs) that they had previously designed to carry base editors — another type of precision gene editor that makes single-letter changes in DNA.

Prime editing efficiently corrects cystic fibrosis mutation in human lung cells

Broad Institute

A three-drug cocktail known as Trikafta has greatly improved patient quality of life since its development in 2019, but can cause cataracts and liver damage and must be taken daily at a cost of about $300,000 per year. The new approach also generated 3.5

Unveiling neoantigen-directed cancer treatment

Drug Target Review

Adaptive Biotechnologies and Genentech entered a partnership in 2019 to develop, manufacture and commercialise novel neoantigen directed T-cell therapies for the treatment of a broad range of cancers. While tumour cells share a majority of their DNA with healthy cells, they also carry numerous unique mutations.

FDA Returns Disappointing News for ALS Stem Cell Therapy

PLOS: DNA Science

Last week DNA Science covered a setback in a clinical trial of a gene therapy for Duchenne muscular dystrophy (DMD). It aims to correct the faulty instructions at the DNA level, straightforward, at least conceptually, because mutations are deletions, of part or all of the gene. That’s not the case for ALS.

The Forgotten Pandemic

Codon

million people with TB went undetected in 2019, but these estimates are uncertain due to inaccuracies in testing. In 2019, physicians were unable to tailor effective antibiotic regimens for 39 percent of new TB cases because the assessments they relied on could not gauge which antibiotics the strains would be susceptible to.

They’ve just finished sequencing the patient’s genome, but they don’t have “DNA sorting” software. billion units of DNA code are transcribed into more than a hundred volumes, each a thousand pages long, in type so small as to be barely legible.” At least, that’s what every textbook says.
