Drug discovery for malaria has been transformed in the last 5 years by the discovery of many new lead compounds identified by phenotypic screening. The process of developing these compounds as drug leads and studying the cellular responses they induce is revealing new targets that regulate key processes in the Plasmodium parasites that cause malaria. We(More)
Post-proline cleaving peptidases are promising therapeutic targets for neurodegenerative diseases, psychiatric conditions, metabolic disorders, and many cancers. Prolyl oligopeptidase (POP; E.C. and fibroblast activation protein α (FAP; E.C. 3.4.24.B28) are two post-proline cleaving endopeptidases with very similar substrate specificities. Both(More)
Liposomes (phospholipid bilayer vesicles) are versatile and robust delivery systems for induction of antibody and T lymphocyte responses to associated subunit antigens. In the last 15 years, liposome vaccine technology has matured and now several vaccines containing liposome-based adjuvants have been approved for human use or have reached late stages of(More)
BACKGROUND Combination drug therapy has reduced plasma HIV to undetectable levels; however, drug-sensitive virus persists in patients' lymphoid tissue. We have reported significant lymphoid tissue drug localization with indinavir-associated lipid nanoparticles (LNPs). Our current objective is to evaluate whether additional enhancement is achievable by(More)
A systematic screen of FDA-approved drugs was performed to identify compounds with in vitro antiviral activities against Ebola virus (EBOV). Compounds active (>50% viral inhibition and <30% cellular toxicity) at a single concentration were tested in dose-response assays to quantitate the antiviral activities in replication and viral entry assays as well as(More)
Human immunodeficiency virus (HIV) persists in lymph nodes and lymphoid tissues even during aggressive drug treatment, likely due to insufficient drug concentrations at this site. Therefore, to eliminate this residual virus, methods that enhance lymph node drug concentrations are currently being evaluated. Although enhanced drug concentrations in tissue(More)
With almost 40 million people infected with human immunodeficiency virus (HIV), it is one of the most devastating diseases with no cure in sight. Over the past two decades, significant progress has been made to identify and validate drug targets for HIV. However, most of the 20 FDA approved drugs are targeted to two enzymes; reverse transcriptase and(More)
Hemopressin is a naturally occurring and therapeutically relevant peptide with applications in hypertension, pain, addiction, and obesity. We had previously demonstrated that hemopressin converts into amyloid-like fibrils under aqueous conditions. However, the amino acid residues that modulate the aggregation propensity of hemopressin were not identified.(More)
Susceptibility to deadly diarrheal diseases is partly due to widespread pediatric vitamin A deficiency. To increase vitamin A coverage in malnourished children, we propose to engineer a probiotic bacterium that will produce β-carotene in the intestine, which will be metabolized to vitamin A. Such a therapy has the potential to broadly stimulate mucosal(More)
Success of cancer prodrugs relying on a foreign gene requires specific delivery of the gene to the cancer, and improvements such as higher level gene transfer and expression. Attaining these objectives will be facilitated in preclinical studies using our newly discovered CNOB-GDEPT, consisting of the produrg: 6-chloro-9-nitro-5-oxo-5H-benzo-(a)-phenoxazine(More)
