Despite extensive research, influenza A virus (IAV) remains a major cause of morbidity, mortality, and healthcare expenditure. Emerging pandemics from highly pathogenic IAV strains, such as H5N1 and pandemic H1N1, highlight the need for universal, crossprotective vaccines. Current vaccine formulations generate strain-specific neutralizing antibodies primarily against the outer coat proteins, hemagglutinin and neuraminidase. In contrast to these highly mutable proteins, internal proteins of IAV are more conserved and are a favorable target for developing vaccines that induce strong T cell responses in addition to humoral immunity. Here, we found that intranasal administration with a single dose of CpG and inactivated …

Human immunodeficiency virus (HIV) patients are often diagnosed in the chronic stage of HIV/AIDS. Combination antiretroviral therapy (cART) has improved quality of life for HIV-infected patients. Present study describes a novel long-acting parenteral formulation of combination antiretroviral (cARV) loaded nano-drugs for treating chronic HIV-1 (cHIV) in a humanized-BLT (hu-BLT) mice model. The cARV (elvitegravir + tenofovir alafenamide + emtricitabine; EVG + TAF + FTC) drugs (mimicking marketed Genvoy® one-pill for HIV-treatment) were encapsulated in poly (lactic-co-glycolic acid) nanoparticles (NPs). To establish cHIV, hu-BLT mice were intravaginally challenged with HIV-1 and maintained for 15 weeks. Plasma viral load (pVL) was monitored …
