Generation, Recovery, and Propagation of a Recombinant Vesicular Stomatitis Virus Expressing the Marburg Virus Glycoprotein.

Vesicular stomatitis virus (VSV)-based vaccination has shown protective efficacy against filovirus infection. Following the approval of a VSV-based vaccine against Ebola virus, there have been efforts toward applying the same platform for other filoviruses, including Marburg virus (MARV) and Sudan virus. Because these vaccines express filovirus glycoproteins, they are also a valuable tool to study filovirus entry under biosafety level 2 conditions.

Vaccine Platform Comparison: Protective Efficacy against Lethal Marburg Virus Challenge in the Hamster Model.

Marburg virus (MARV), a filovirus, was first identified in 1967 in Marburg, Germany, and Belgrade, former Yugoslavia. Since then, MARV has caused sporadic outbreaks of human disease with high case fatality rates in parts of Africa, with the largest outbreak occurring in 2004/05 in Angola. From 2021 to 2023, MARV outbreaks occurred in Guinea, Ghana, New Guinea, and Tanzania, emphasizing the expansion of its endemic area into new geographical regions.

Coordination of fungal biofilm development by extracellular vesicle cargo.

The fungal pathogen Candida albicans can form biofilms that protect it from drugs and the immune system. The biofilm cells release extracellular vesicles (EVs) that promote extracellular matrix formation and resistance to antifungal drugs. Here, we define functions for numerous EV cargo proteins in biofilm matrix assembly and drug resistance, as well as in fungal cell adhesion and dissemination.

Overweight and obese children with optimal control in the T1D Exchange Registry: How are they different from lean children with optimal control?

Aims: Increased adiposity is a risk factor for suboptimal diabetes control and cardiovascular disease (CVD) complications. Our goal was to identify modifiable behavioral characteristics of overweight and obese pediatric patients with type 1 diabetes mellitus (T1DM) who achieve optimal glycemic control and to evaluate their CVD risk compared to lean patients. Our hypothesis was that optimally controlled obese and overweight participants require more total daily insulin and are at higher CVD risk compared to optimally controlled lean participants.
