Lab Description

We are working on new strategies for organ protection by boosting highly conserved signaling pathways that Nature has designed to protect cells from various forms of stress-induced damage. Small ubiquitin-like modifier (SUMO1-3) conjugation is an archetypical signaling pathway that is known to protect cells from various kinds of stress. Our data support the notion that targeting SUMO conjugation is a promising new strategy for protecting organs in the clinical setting.Our long-term goal is to improve outcomes in patients who suffer a stroke or other forms of brain ischemic injury.
