Mechanisms of neurovascular damage and repair in cerebral ischemia and traumatic brain injury

Research Summary

Dr. Yin’s research interest is to study the cellular & molecular mechanisms and therapeutic strategies of cerebrovascular and neural dysfunction after ischemic stroke and traumatic brain injury by using state-of-the-art cell biology, molecular biology, biochemistry, pharmacology, morphology, imaging, behavior and transgenic animal approaches. Currently, major ongoing research activities in Dr. Yin’s laboratory focus on investigating how non-coding RNAs (microRNAs, long non-coding RNAs) and Krüppel-like transcription factors regulate neurovascular pathophysiology (Blood-Brain Barrier disruption, Vascular and parenchymal inflammation, Angiogenesis, etc.), affect neurological outcomes, and modulate brain repair and functional recovery after ischemic stroke and traumatic brain injury. The long-term research goal of Dr. Yin’s laboratory is to discover novel molecular or pharmaceutical targets for the development of effective vaso-/neuro-protective or neurorestorative therapies against ischemic stroke and traumatic brain injury.
