New technology could offer patients with brain disorders pills to regenerate neurons

Our lab aims to reverse glial scar back to normal neural tissue by gene delivery and/or chemical treatment.

Recently, We have discovered a cocktail of small molecules that can reprogram human brain astroglial cells into neuron-like cells after eight-to-ten days of chemical treatment.The small molecule induced neurons could survive for more than five months in cell culture, where they formed functional synaptic networks. When injected in the brains of living mice,the reprogrammed human neurons were integrated into the neural circuits and survived there for at least one month.

The new technology opens the door to the future development of drugs that patients with brain disorders could take as pills to regenerate neurons!

Graduate student Lu Xu wears a device designed by engineers, at Washington University in St. Louis, that targets ultrasound waves to precise spots in the brain. Such targeting is the first step in a sonobiopsy, a noninvasive technique invented by Washington University researchers that uses ultrasound and microbubbles to release biomolecules from brain tumors. The biomolecules then can be collected via a blood draw, analyzed and used to inform treatment decisions. Xu is part of a research team that demonstrated that sonobiopsy is safe and feasible for use in people.
