Experimental Antibodies for Parkinson’s and Alzheimer’s May Cause Harmful Inflammation

A new study reveals some experimental antibody treatments for neurodegenerative disorders increase neuroinflammation. The effect was seen in human microglia, not mouse microglia. This may explain why mouse studies have shown these treatments to be effective, but the effect has not been replicated in human studies.

More evidence Parkinson’s disease may start in the gut

Enteric neurons appear to play a key role in the development of Parkinson's disease. The findings support the hypothesis and previous studies that the neurodegenerative disease may start in the gut before spreading to the brain. Researchers also found oligodendrocytes were affected during the early stages of Parkinson's, even before the loss of dopaminergic neurons.
