A St. Jude-led collaboration characterized the unique features of hospitalized infants’ immune response to SARS-CoV-2, the virus that causes COVID-19. Findings show that the immune response looked different in these infants compared to other ages, including increases in the antiviral interferon protein and interferon-stimulated genes in most immune cells, paired with high levels of inflammatory cytokines in their blood.
Successfully treating type 2 diabetes may involve focusing on brain neurons, rather than simply concentrating on obesity or insulin resistance, according to a study published today in the Journal of Clinical Investigation.
For several years, researchers have known that hyperactivity of a subset of neurons located in the hypothalamus, called AgRP neurons, is common in mice with diabetes.
“These neurons are playing an outsized role in hyperglycemia and type 2 diabetes,” said UW Medicine endocrinologist Dr. Michael Schwartz, corresponding author of the paper.
