Novel potent antimicrobial from thermophilic bacterium

March 11, 2019 dna 0
Microbiologists have discovered a new glycocin, a small antimicrobial peptide with a sugar group attached, which is produced by a thermophilic bacterium and is stable at relatively high temperatures. They also succeeded in transferring the genes required to produce this glycocin to an E. coli bacterium. This makes it easier to produce and investigate this compound, which could potentially be used in biofuel production.

Discovery of the genetic ‘conductor’ of brain stem cells

March 11, 2019 dna 0
Our brain comprises 85 billion nerve cells and just as many so-called glial cells. But what decides when and how many of them become neurons or glial cells? A new study has shown how the Foxg1 gene plays a fundamental role in piloting the differentiation of stem cells, guaranteeing that neurons and glial cells are produced in the right quantity and at the right moment. The research opens new roads to understanding and treating incurable genetic diseases.

Major genetic study confirms that many genes contribute to risk for Tourette’s syndrome

March 11, 2019 dna 0
A meta-analysis of multiple studies into the genetic background of Tourette’s syndrome (TS) — a neurodevelopmental disorder characterized by chronic involuntary motor and vocal tics — finds that variants in hundreds of genes, working in combination, contribute to the development of the syndrome and suggests that Tourette’s is part of a continuous spectrum of tic disorders, ranging from mild, sometimes transient tics to severe cases that can include psychiatric symptoms.
