A nanofiber based antiviral (TAF) prodrug delivery system.

HIV and hepatitis B are two of the most prevalent viruses globally, and despite readily available preventive treatments unforgiving treatment regimens still exist, such as daily doses of medicine that are challenging to maintain especially in poorer countries. More advanced and longer-lasting delivery vehicles can potentially overcome this problem by reducing maintenance requirements and significantly increase access to medicine. Here, we designed a technology to control the delivery of an antiviral drug over a long timeframe via a nanofiber based delivery scaffold that is both easy to produce and use.

A macrophage-targeted platform for extending drug dosing with polymer prodrugs for pulmonary infection prophylaxis.

Pulmonary melioidosis is a bacterial disease with high morbidity and a mortality rate that can be as high as 40% in resource-poor regions of South Asia. This disease burden is linked to the pathogen's intrinsic antibiotic resistance and protected intracellular localization in alveolar macrophages. Current treatment regimens require several antibiotics with multi-month oral and intravenous administrations that are difficult to implement in under-resourced settings.

Mannose Conjugated Polymer Targeting Biofilms.

Biofilms are one of the most challenging obstacles in bacterial infections. By providing protection against immune responses and antibiotic therapies, biofilms enable chronic colonization and the development of antibiotic resistance. As previous clinical observations and studies have shown, traditional antibiotic therapy alone cannot effectively treat and eliminate biofilm forming infections due to the protection conferred by the biofilm.

Flow-dependent YAP/TAZ activities regulate endothelial phenotypes and atherosclerosis.

The focal nature of atherosclerotic lesions suggests an important role of local hemodynamic environment. Recent studies have demonstrated significant roles of Yes-associated protein (YAP) and transcriptional coactivator with PDZ-binding motif (TAZ) in mediating mechanotransduction and vascular homeostasis. The objective of this study is to investigate the functional role of YAP/TAZ in the flow regulation of atheroprone endothelial phenotypes and the consequential development of atherosclerotic lesions.
