Changes in gut mucus may contribute to Alzheimer's, Parkinson's, and other neurological disorders. Researchers noted changes in types of gut mucus bacteria in those with a range of neurological disorders compared to their healthy peers. Findings suggest those with reduced gut mucus protection may be more susceptible to gastrointestinal problems.
Researchers use optogenetic based deep brain stimulation to help treat motor dysfunction in animal models of Parkinson's disease. The new technique provides insights into why DBS works and ways in which it can be improved on a patient-by-patient basis.
A new method called Tox-seq found only one sub-group of microglia caused oxidative stress. The gene expression signatures of this sub-group from a mouse model matched patterns observed in cells suspected of causing damage in progressive multiple sclerosis patients. The pattern of gene expression associated with oxidative stress in mouse cells included genes involved in coagulation.
