One-Time Treatment Generates New Neurons, Eliminates Parkinson’s Disease in Mice

UC San Diego researchers have discovered that a single treatment to inhibit a gene called PTB in mice converts native astrocytes, brain support cells, into neurons that produce the neurotransmitter dopamine. As a result, the mice’s Parkinson’s disease symptoms disappear.

New technique allows scientists to measure mitochondrial respiration in frozen tissue

UCLA scientists have developed a method for restoring oxygen-consumption activity to previously frozen mitochondria samples. By speeding up research, investigators hope to accelerate the diagnosis of people living with mitochondrial diseases and secondary disorders in which mitochondria play a key role, including diseases related to aging, metabolism and the heart.

The Parkinson’s disease gut has an overabundance of opportunistic pathogens

A 2003 hypothesis says Parkinson’s disease is caused by a gut pathogen that could spread to the brain through the nervous system. No evidence was found until now; researchers report for the first time a significant overabundance of a cluster of opportunistic pathogens in the PD gut.
