Carver College of Medicine News: Drug protects older mice from worst effects of COVID-19 

An experimental drug that counters immune aging, effectively prevents death in older mice with severe COVID-19, suggesting it may have potential as a therapy to protect older people who are most at risk from the disease. The new findings by researchers with University of Iowa Health Care were published recently in the journal Nature.

Carver College of Medicine News: Inhaled COVID-19 vaccine prevents disease and transmission in animals

In a new study assessing the potential of a single-dose, intranasal COVID-19 vaccine, a team from the University of Iowa and the University of Georgia found that the vaccine fully protects mice against lethal COVID-19 infection. The vaccine also blocks animal-to-animal transmission of the virus. The findings were published July 2 in the journal Science Advances.

Carver College of Medicine News: Repurposed mouse model sheds light on loss of smell in COVID-19

A repurposed mouse model can develop symptoms of both severe COVID-19 (lung damage, blood clots, abnormal blood vessels, and death) and also of milder disease, including loss of the sense of smell, according to a new University of Iowa study published in Nature. When COVID-19 started spreading across the world earlier this year, UI researchers Stanley Perlman, MD, PhD, and Paul McCray, MD, realized that a mouse model they had created a decade earlier to study SARS might be an invaluable tool for understanding the concerning new disease and for testing potential treatments. In the new study, Perlman, McCray, and colleagues present a detailed characterization of the effects of SARS-CoV-2 infection in these K18-hACE2 mice.

Carver College of Medicine News: McCray Lab & UI cystic fibrosis research team receive $11.5 million NIH grant to develop new therapies

A team of cystic fibrosis experts with University of Iowa Health Care has been awarded a five-year, $11.5 million grant by the National Heart, Lung, and Blood Institute to research molecular therapies for cystic fibrosis (CF) lung disease. “The overall goal of this program project grant is to better understand the cellular basis of CF airway disease and use this knowledge to direct new therapies towards its prevention or treatment,” says Paul McCray, MD, principal investigator of the grant and a professor in the UI Stead Family Department of Pediatrics, and the Department of Microbiology and Immunology in the UI Carver College of Medicine.

Gene therapy could offer an inclusive cure for cystic fibrosis (Nature, July 29, 2020)

Scientists have been trying for 30 years to wield gene therapy against cystic fibrosis. In past efforts, the viruses that they engineered to deliver the working copy of the gene into cells didn’t work effectively. Now, thanks to better vectors and other innovations in delivering genetic sequences, gene-replacement therapies are nearing clinical trials, and the field is gaining momentum.
This article highlights the contributions that investigators at the University of Iowa have made and continue to make to advance gene therapy for CF.

Carver College of Medicine News: Off-the-shelf tool for making mouse models of COVID-19 

S Perlman & P McCray
A major hurdle to developing and testing new anti-viral therapies and vaccines for COVID-19 is the lack of good, widely available animal models of the disease. Researchers at the University of Iowa Carver College of Medicine and Medical University, Guangzhou, in China, have developed a simple tool to overcome that bottleneck. The researchers have created a gene therapy approach that can convert any lab mouse into one that can be infected with SARS-CoV-2 and develops COVID-like lung disease. The international team, led by Paul McCray, MD, and Stanley Perlman, PhD, at the UI, and Jincun Zhao, PhD, at Medical University, Guangzhou, have made their gene therapy vector freely available to any researchers who want to use it.
