Researchers find unique genetic mutation in 74-year-old man with Parkinson's disease

Mutations in the human genome may be responsible for many diseases. In the case of Parkinson's disease (PD), five locations have been the subject of recent attention. Variants of one of these locations, ACMSD (aminocarboxymuconate semialdehyde decarboxylase), may be implicated in PD, but until now, no mutations in ACMSD have been found in any PD patients.

Protein-rich diet may foster more tolerant, less inflammatory gut environment

Immune cells patrol the gut to ensure that harmful microbes hidden in the food we eat don't sneak into the body. Cells that are capable of triggering inflammation are balanced by cells that promote tolerance, protecting the body without damaging sensitive tissues.

Innovative strategy can reverse symptoms in neurodegenerative diseases

Alzheimer's and Parkinson's disease are the two most common neurodegenerative disorders worldwide and cause untold suffering to millions of patients and their families. Treatments for these diseases are limited, and no cures exist. Now, a new study describes an innovative strategy that reverses symptoms in these neurodegenerative diseases - at least in fruit flies which had been genetically altered to model the diseases.

Study reveals direct regulatory role of serotonin in rheumatoid arthritis

For the first time, serotonin (5-hydroxytryptamine, 5-HT) has been directly implicated in the pathophysiology of rheumatoid arthritis (RA). Although 5-HT is predominantly known as a neurotransmitter within the central nervous system, new evidence points to additional important functions for serotonin in the periphery.
