Two items relevant to long COVID

One of the tricky issues in studying in long COVID is: how widely do researchers cast their net? Initial reports acknowledged that people who were hospitalized and in intensive care may take a while to get back on their feet. But the number of people who had SARS-CoV-2 infections and were NOT hospitalized, yet experienced lingering symptoms, may be greater. A recent report from the United Kingdom, published in PLOS Medicine, studied more than Read more

Signature of success for an HIV vaccine?

Efforts to produce a vaccine against HIV/AIDS have been sustained for more than a decade by a single, modest success: the RV144 clinical trial in Thailand, whose results were reported in 2009. Now Emory, Harvard and Case Western Reserve scientists have identified a gene activity signature that may explain why the vaccine regimen in the RV144 study was protective in some individuals, while other HIV vaccine studies were not successful. The researchers think that this signature, Read more

Reversing liver fibrosis via adiponectin

Non-alcoholic fatty liver disease (NAFLD) is one of the most common liver conditions in the United States, affecting 30 percent of the population, and increasing — and likely to catch up in prevalence with obesity and diabetes. In NAFLD, fat content of the liver is elevated to 6 percent or more in people who drink in moderation or not at all. Patients will first present with elevated liver enzyme values in blood tests, but then an imaging test or tissue biopsy may be ordered to evaluate the extent of the damage. NAFLD is mostly asymptomatic and is variable in severity; a majority of those afflicted do not need drug treatments. However, NAFLD is thought to be a preliminary condition that can eventually progress to severe manifestations, such as cirrhosis, hepatocellular carcinoma, and end stage liver failure.

At Emory, Frank Anania, director of the Department of Medicine’s Division of Digestive Diseases, and his colleagues are developing a tool to treat liver disease. A recent publication in the FASEB Journal describes their investigation into the potential for the hormone adiponectin to modulate liver fibrosis.

Adiponectin is produced by adipose tissue, but is known to decrease in overweight people with metabolic disease. Research by others indicates that it may prevent heart and kidney fibrosis. The Emory team’s studies were conducted to determine if adiponectin could also reduce liver fibrosis.

Looking at simple foods to protect against breast cancer

Researchers at the Winship Cancer Institute of Emory University have found that the hormone adiponectin may reduce the ability of cancer cells to migrate from the breast and invade other tissues. Adiponectin appears to protect against the effects of obesity on metabolism, the heart and blood vessels, the researchers say.

Fat cells make up most of the breast tissue, and some of the hormones produced by fat cells can have tumor-stimulating effects. Previous studies have shown that women with high body mass index (highest fifth) have double the death rate from breast cancer compared to those in the lowest fifth.

Dipali Sharma, PhD

The key to translating this research for patient care lies in finding a way to increase a person’s adiponectin, says Dipali Sharma, PhD, assistant professor of hematology and medical oncology at Winship.

Currently, Winship scientists are testing a molecule found in certain foods that appears to mimic the effects of adiponectin. The molecule is found in grapes, cabbage and green tea.
