Lung Cancer Targeted Chemotherapy Via Herceptin Based Chimeric Antigen Receptor (Car) Engineered T Cell Membrane Coated Synthetic Nanoparticles, Serkan Yaman
Bioengineering Dissertations
Cell membrane-derived nanoparticles recently caught attention due to their desirable features in drug delivery such as mimicking properties of native tissue and cells, avoiding systemic clearance, and alleviating foreign body responses. Besides nanoparticle technology, adoptive immunotherapy has emerged for its promising treatment modalities, including cancer specificity. Our long-term goal for this research is to develop a biomimetic drug carrier based on chimeric antigen receptor (CAR) transduced T cell membranes. In the study, anti-cancer drug afatinib loaded poly(D,L-lactide-co-glycolide) (PLGA) nanoparticles (NPs) co-extruded with anti her-2 based chimeric antigen receptor (CAR) Jurkat T cell membranes. Anti her-2 CAR-T cells were produced by …

Development Of An In Vitro Tbi Models And Validation Of Nanodelivery For Restoration Of Disrupted Brain Endothelium, Edidiong I. Inyang
Bioengineering Dissertations
Blast-induced traumatic brain injury (bTBI) is a serious concern among military personnel and their families. Although the mechanisms responsible for disruption to the brain are not well understood, the development of reliable diagnosis along with effective therapeutic treatment is urgently warranted. Recent findings suggest that shockwaves produced by a blast can generate micron-size bubbles that subsequently collapse in the brain tissue. The collapse of microbubbles (referred to as microcavitation) may compromise the integrity of the blood-brain barrier (BBB). Moreover, addiction to the psycho-stimulant drugs (PSDs), e.g. cocaine and alcohol which are known to cause toxicity due to oxidative stress, can …
A Ph-Sensitive Delivery System For The Prevention Of Dental Caries Using Salivary Proteins, Yi Zhu
A Ph-Sensitive Delivery System For The Prevention Of Dental Caries Using Salivary Proteins, Yi Zhu
Electronic Thesis and Dissertation Repository
Dental caries remains one of the most common chronic diseases worldwide. Salivary proteins such as histatins have demonstrated biological functions directly related to tooth homeostasis and prevention of dental caries. However, histatins are susceptible to the high proteolytic activities in the oral environment. Therefore, pH-sensitive chitosan nanoparticles (CNs) have been proposed as potential carriers to target major oral diseases that occur under acidic conditions (e.g. dental caries and dental erosion). Four different types of chitosan polymers were investigated and the optimized CNs successfully loaded histatin 3 and released it selectively under acidic conditions. Through loading the survival time of histatin …
Cell Imaging And Data Analysis For Biomaterial-Mammalian Co-Cultures, Jefferson Pontsler
Cell Imaging And Data Analysis For Biomaterial-Mammalian Co-Cultures, Jefferson Pontsler
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Microscopic bioimaging is a useful approach to study cell-biomaterial interactions which are vital to the biomedical application of biomaterials. Through microscopic imaging, numerous cellular responses, such as proliferation, uptake, and death, can be recorded, characterized and analyzed.
In this thesis, I first provided basic introductions to the imaging techniques and analysis tools, especially those that are highly relevant to the studies of biomaterials and cell interactions. I also detailed the adaptation of these techniques and tools in the application of two specific research projects in biomaterials, with special focuses on the imaging and analysis.
The first project assessed the subtle …
