Gasdermin B (GSDMB) overexpression/amplification occurs in about 60% of HER2 breast cancers, where it promotes cell migration, resistance to anti-HER2 therapies, and poor clinical outcome. Thus, we tackle GSDMB cytoplasmic overexpression as a new therapeutic target cancers.We have developed targeted nanomedicine based on hyaluronic acid-biocompatible nanocapsules, which allow the intracellular delivery specific anti-GSDMB antibody into cancer cells both vitro vivo.Using different models...
Bovine milk-derived exosomes have recently emerged as a promising nano-vehicle for the encapsulation and delivery of macromolecular biotherapeutics. Here we engineer high purity bovine milk (mExo) with modular surface tunability oral small interfering RNA (siRNA). We utilize low-cost enrichment method combining casein chelation differential ultracentrifugation followed by size exclusion chromatography, yielding mExo concentration purity. Using in vitro models, demonstrate that negatively...

Abstract A growing global health concern, Lyme disease has become the most common tick-borne in United States and Europe. Caused by bacterial spirochete Borrelia burgdorferi sensu lato (sl), this can be debilitating if not treated promptly. Because diagnosis is challenging, prevention remains a priority; however, previously licensed vaccine no longer available to public. Here, we designed six component that elicits antibody (Ab) responses against all strains commonly cause humans. The outer...
Abstract Preparation of sophisticated delivery systems for nanomedicine applications generally involve multi-step procedures using organic solvents. In this study, we have developed a simple self-assembling process to prepare docetaxel-loaded hyaluronic acid (HA) nanocapsules by self-emulsification without the need solvents, heat or high shear forces. These nanocapsules, which comprise an oily core and shell consisting assembly surfactants hydrophobically modified HA, mean size 130 nm, zeta...
Abstract Molecularly imprinted polymers (MIPs) are tailor‐made synthetic antibodies possessing specific binding cavities designed for a target molecule. Currently, MIPs protein targets synthesized by imprinting short surface‐exposed fragment of the protein, called epitope or antigenic determinant. However, finding par excellence that will yield peptide “synthetic antibody” cross‐reacting exclusively with from which it is derived, not easy. We propose computer‐based rational approach to...
Tumor Necrosis Factor-α (TNF-α) is a cytokine that normally produced by immune cells when fighting an infection. But, too much TNF-α as in autoimmune diseases, this leads to unwanted and persistent inflammation. Anti-TNF-α monoclonal antibodies have revolutionized the therapy of these disorders blocking preventing its binding receptors, thus suppressing Herein, we propose alternative form molecularly imprinted polymer nanogels (MIP-NGs). MIP-NGs are synthetic obtained nanomoulding...

Exosomes have emerged as a promising tool for the delivery of drugs and genetic materials, owing to their biocompatibility non-immunogenic nature. However, challenges persist in achieving successful oral due susceptibility degradation harsh gastrointestinal (GI) environment impeded transport across mucus-epithelium barrier. To overcome these challenges, we developed high-purity bovine milk exosomes (mExo) scalable efficient drug system, which can be customized by incorporating hydrophilic...
We report a modular approach to synthesize maleimido group containing hydrophilic dolastatin 10 (Dol10) derivatives as drug-linkers for the syntheses of antibody-drug conjugates (ADCs). Discrete polyethylene glycol (PEG) moieties different chain lengths were introduced part linker impart hydrophilicity these drug linkers. The synthesis process involved construction PEG tetrapeptide intermediate (N-methylvaline-valine-dolaisoleucine-dolaproine), which subsequently coupled with dolaphenine...
