Blackburn Laboratory

OVERVIEW

The laboratory of Dr. Spiros Blackburn is dedicated to advancing the understanding of subarachnoid hemorrhage (SAH) and cerebrovascular disorders such as cerebral aneurysm and to promote enhancements in treatments and therapies. It is our mission to conduct basic and translational research using interdisciplinary approach and techniques, promote enhancements in treatments and therapies, and improve the outcomes of patients affected by subarachnoid hemorrhage and vascular disorders.

Dr. Spiros Blackburn is an Associate Professor in the Department of Neurosurgery at the University of Texas Health Science Center in Houston, where he serves as a cerebrovascular neurosurgeon. He obtained his MD at UT Southwestern and completed internship and fellowship at Washington University and Emory University. As a clinician, he has participated in a number of clinical trials and clinical research to advance the understanding of brain aneurysms and contributed to translational research studies.

CURRENT PROJECTS

Correlation between haptoglobin genotype and hypercoagulability and inflammation biomarkers after SAH
Haptoglobin has been indicated to cerebral vasospasm, delayed cerebral ischemia, and poor outcome of patient after SAH. We use human biological samples to validate haptoglobin as a predictor of clinical outcome post SAH, and investigate the correlation between inflammatory and hypercoagulability biomarkers and haptoglobin.

Cerebrovascular endothelial cell dysfunction in SAH
SAH has been shown to induce multifaceted regulatory mechanisms of cerebral endothelial dysfunctions. We use animal models to determine the role of inflammatory signaling in endothelial cell dysfunction, investigate the signaling events responsible for endothelial cell injury affecting blood brain barrier integrity, and analyze the role of endothelial cell signaling in attenuating SAH-induced cerebral dysfunctions.
