A study published in July 2020 hypothesized a link between the presence of bradykinin, a well-known peptide, and severe cases of COVID-19. Vardan Karamyan, Ph.D., an associate professor and vice chair for the Texas Tech University Health Sciences Center (TTUHSC) Jerry H. Hodge School of Pharmacy Department of Pharmaceutical Sciences, had not previously conducted or evaluated any research related to COVID-19. However, he found the article intriguing because it discussed bradykinin, one of three specific peptides with which his lab has much well-published experience.
