Cerebrovascular Disease News and Research

RSS

Cerebrovascular disease is a group of brain dysfunctions related to disease of the blood vessels supplying the brain. Hypertension is the most important cause; it damages the blood vessel lining, endothelium, exposing the underlying collagen where platelets aggregate to initiate a repairing process which is not always complete and perfect. Sustained hypertension permanently changes the architecture of the blood vessels making them narrow, stiff, deformed, uneven and more vulnerable to fluctuations in blood pressure.

UTHSC researchers receive $2.4 million to study the role of cholesterol in brain artery health

Alex Dopico, MD, PhD, professor and Van Vleet Chair of Excellence in the Department of Pharmacology, Addiction Science, and Toxicology, and Anna Bukiya, PhD, associate professor in the Department of Pharmacology, Addiction Science, and Toxicology, have been awarded $2.4 million from the National Heart, Lung, and Blood Institute to explore how cholesterol interacts with the mechanisms that modulate blood vessel function in the brain.

Metabolic diseases alter ACE2 expression and increase COVID-19 severity

A new study published on the preprint server medRxiv in June 2020 reports that one mechanism for this variable severity is the differential expression of the ACE2 receptor in various metabolic conditions, thereby facilitating viral entry into the host cells.

No specific COVID-19-linked lesions found despite extensive organ injury

A recent paper published online on the preprint server medRxiv in May 2020 reports autopsy results on COVID-19 patients. The paper concludes that there were no specific hallmark lesions of COVID-19 in any of the many organs found to be injured by the infection in patients who died of the disease.
