Treatment of severe malaria with intravenous (IV) artesunate should always be followed by a complete treatment course of an appropriate oral antimalarial regimen. Prior to this approval, IV artesunate was only available to patients through … Continue reading FDA Approves Only Drug in U.S. to Treat Severe #Malaria

Cigarette #smoke exposure and inflammatory signaling increase the expression of the #SARS-CoV-2 receptor ACE2 in the respiratory tract

Abstract The factors mediating fatal SARS-CoV-2 infections are poorly understood. Here, we show that cigarette smoke causes a dose-dependent upregulation of Angiotensin Converting Enzyme 2 (ACE2), the SARS-CoV-2 receptor, in rodent and human lungs. Using single-cell sequencing data, we demonstrate that ACE2 is expressed in a subset of secretory cells in the respiratory tract. Chronic … Continue reading Cigarette #smoke exposure and inflammatory signaling increase the expression of the #SARS-CoV-2 receptor ACE2 in the respiratory tract
