The role of CRISPR in microbiome engineering breakthroughs

Drug Target Review

When faced with a viral threat, bacterial cells developed an immune response by capturing and copying DNA fragments of viruses. This allowed bacteria to recognise subsequent attacks and cleave the viral DNA to stop the viral infection. It was also discovered that the Cas enzyme was responsible for DNA cleavage.

Not all neoantigens are created equal

Drug Target Review

During the process of transformation from a normal cell into a cancer cell, a cell acquires a series of changes, or mutations, in its DNA. But DNA mutations can also result in changes to the proteins that are displayed on the surface of the cancer cell. Neoantigens are recognised as non-self and trigger an immune response.

Designing a Better Probiotic. CRISPR Hubris?

PLOS: DNA Science

The molecular tools of CRISPR were borrowed and developed from the natural immune response of bacteria to viruses – bacteriophages – that infect them. CRISPR may make sense for replacing a single mutant gene, like the one behind sickle cell disease, for which a CRISPR-based gene therapy was recently approved.

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). Also recently, FDA’s Cellular, Tissue, and Gene Therapies Advisory Committe turned down a stem cell treatment for amyotrophic lateral sclerosis, aka ALS, Lou Gehrig’s disease, or motor neuron disease.
