Targeted delivery of drugs across endothelial barriers remains a formidable challenge, especially in the case of the brain, where the blood-brain barrier severely limits entry of drugs into the central nervous system. Nanoparticle-mediated transport of peptide/protein-based drugs across endothelial barriers shows great potential as a therapeutic strategy in a wide variety of diseases. Functiona...
Numerous targeted nanotherapeutics have been described for potential treatment of solid tumors. Although attention has focused on antigen selection and molecular design of these systems, there has been comparatively little study of how cellular heterogeneity influences interaction of targeted nanoparticles with tumor cells. Antigens, such as HER2/ERBB2, are heterogeneously expressed across diff...
The use of mouse oocytes as a model for studying female meiosis is very important in reproductive medicine. Gene knockdown by specific small interfering RNA (siRNA) is usually the first step in the study of the function of a target gene in mouse oocytes during in vitro maturation. Traditionally, the only way to introduce siRNA into mouse oocytes is through microinjection, which is certainly les...
Immune protection against infectious diseases is most effective if located at the portal of entry of the pathogen. Hence, there is an increasing demand for vaccine formulations that can induce strong protective immunity following oral, respiratory, or genital tract administration. At present, only few mucosal vaccines are found on the market, but recent technological advancements and a better u...
Nanoparticle Quantization With a Stretchable Nanopore by Edolfo Garza-Licudine This paper demonstrates initial results with a portable device for nanoparticle detection and quantization, called the “qNano.” The qNano instrument allows for detection of charged particles passing through a nanopore via electrophoresis. The instrument uses a stretchable plastic membrane with a pore on the order of ...
Application of viruses as a carrier, though not safe, to deliver genes to eye tissue was successful. However, a safer, nonviral, biocompatible lipid-based nanoparticle has never been tested to treat blinding eye diseases. We created an artificial virus using a nanoparticle, liposome-protamine-DNA complex (LPD), modified with a cell permeable peptide and a nuclear localization signaling (NLS) pe...
In anti-cancer therapy mediated by a nanoparticle-based drug delivery system (DDS), overall efficacy depends on the release efficiency of cargos from the nanoparticles in the cancer cells as well as the specificity of delivery to tumor tissue. However, conventional liposome-based DDS have no mechanism for specifically releasing the encapsulated cargos inside the cancer cells. To overcome this b...
objective(s): soluble leishmania antigens (sla) provide suitable protection against leishmaniasis in murine model when delivered by an appropriate delivery system. liposomes have been shown to be suitable vaccine delivery systems against leishmaniasis, however, the phospholipase-a (pla) activity of sla is a drawback to prepare a stable liposomal sla. one strategy to overcome this problem might ...
Background Immune checkpoint inhibitors (CIs) have emerged as a revolutionary treatment for several cancer types. Despite significant improvement in prognosis some patients, there are associated challenges. CIs do not work well on immune-cold tumors, thereby eliciting an insufficient immune response. They also effective tumors with low mutational burden due to dependance tumor self-antigens rec...
Traditionally, the goal of nanoparticle-based chemotherapy has been to decrease normal tissue toxicity by improving drug specificity to tumors. The enhanced permeability and retention effect can permit passive accumulation into tumor interstitium. However, suboptimal delivery is achieved with most nanoparticles because of heterogeneities of vascular permeability, which limits nanoparticle penet...
