ALS Trajectory May Be Affected By Gut Microbes

Intestinal microbes, collectively termed the gut microbiome, may affect the course of amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease, researchers at the Weizmann Institute of Science have shown in mice. Progression of an ALS-like disease was slowed after the mice received certain strains of gut microbes or substances known to be secreted […]

CRISPR Helps Identify New Biomarker For Alzheimer’s Disease

STIM1 protein expression decreases with the progression of neurodegeneration in Alzheimer’s disease, new research indicates. Conducted at the Institute of Molecular Pathology Biomarkers, University of Extremadura, in Badajoz, Spain, the study’s aim was to develop a model for studying Alzheimer’s disease (AD) of sporadic origin—in other words, AD that is not due to a hereditary […]

Neutral Evolution: The Randomness That Shapes Our DNA

Darwin famously thought of evolution as a force for creation and improvement. Evolution, in his eyes, was synonymous with natural selection and survival of the fittest – a process that optimizes life to thrive in its environment and produce greater numbers of offspring. A century later, however, the great population geneticist Motoo Kimura challenged this […]

New Immune Response Pathway Uses Gasdermin D

A new line of defence deployed by the immune system against bacteria has been identified in a University of Queensland study. The new understanding of one of the body’s immune defence mechanisms could lead to the development of novel therapeutic targets for conditions such as cancer and autoimmune diseases. “Bacteria are often quickly killed by […]
