Development Of Macromolecular Prodrug Of Sinomenine For The Treatment Of Rheumatoid Arthritis, Roshni Mukundan

Theses & Dissertations

Inflammation is a natural response of the body to infections or any potential threat to the body. But, sometimes the immune system attacks its own body causing persistent inflammation leading to inflammatory diseases. One of the common chronic inflammatory diseases is rheumatoid arthritis (RA) which causes inflammation of the synovial membrane. The current treatments for RA are effective in controlling the symptoms but they come with severe side effects and economic burden. Further, the management of pain is still a problem with these drugs. Sinomenine is a natural alkaloid obtained from the Chinese medicinal plant Sinomenium acutum that has been …

Rilpivirine-Associated Aggregation-Induced Emission Enables Cell-Based Nanoparticle Tracking, Insiya Mukadam

Theses & Dissertations

Antiretroviral therapy (ART) has improved the quality and duration of life for people living with human immunodeficiency virus (HIV) infection. However, limitations in drug efficacy, the emergence of viral mutations and the paucity of cell-tissue targeting remain. We posit that to maximize ART potency and therapeutic outcomes newer drug formulations that reach HIV cellular reservoirs need to be created. In a step towards achieving this goal we discovered the aggregation-induced emission (AIE) property of the non-nucleoside reverse transcriptase inhibitor Rilpivirine (RPV) and used it as a platform for drug cell and subcellular tracking. RPV nanocrystals were created with endogenous AIE …

Theranostics For Antiretroviral Biodistribution And Pharmacokinetics, Brendan M. Ottemann

Theses & Dissertations

RATIONALE: Our laboratories birthed the field of human immunodeficiency virus (HIV) theranostics. The new field allows simultaneous detection (diagnostics) and treatment (therapeutic) for the identification, treatment and inevitable elimination of virus in cell and tissue compartments. By employing theranostics, antiretroviral drugs (ARVs) can be tracked in lymph nodes, gut, spleen and liver. Cellular viral reservoirs including CD4+ T cell populations and mononuclear phagocytes (MP; monocytes, macrophages, microglia and dendritic cells) along with subcellular endosomal structures can now be targeted for drug delivery bringing therapeutics to areas where virus replicates. The overarching idea rests in improving precision targeted ARV delivery. …

Development Of C5ar-Targeted Nanoparticles For Delivery Of Vaccines, Shailendra Bharadwaj Tallapaka Venkata Sesha

Theses & Dissertations

Since the early attempts of Benjamin Jesty at inducing immunity against smallpox and the pioneering work of Edward Jenner, vaccination has been, and continues to remain, the principal method of protection from diseases. However, most of the successful vaccines have been against pathogens that do not have major mechanisms to evade the immune system. So far, many life-threatening diseases like hepatitis C, HIV infection, malaria etc., have been resistant to existing vaccination strategies. Thus, there is an urgent need to develop new vaccination strategies that can generate long-lived protective immunity against such pathogens.

The purpose of this thesis is to …

Role Of Macrophages In Muscle Transfection With Pdna/Pluronic Formulation, Vivek Mahajan

Theses & Dissertations

Non-ionic amphiphilic block copolymers of poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO), Pluronics, arranged in a tri-block structure PEO-PPO-PEO, have raised a considerable interest in skeletal muscle Gene Therapy. Previous studies have demonstrated that co-administration of Pluronics with naked plasmid DNA (pDNA) by direct i.m. injection enhanced transgene expression not only in muscle but also in distal lymphoid organs (spleen and lymph nodes) and this response was strain-dependent; not observed in athymic (BALB/c nu/nu) mouse; suggesting a role of immune cells in gene transfer to skeletal muscles. Therefore, we first evaluated the role of inflammation and inflammatory cells, on muscle …
