(1) Background: Cytoplasmic delivery of antigens is crucial for the induction of cellular immunity, which is an important immune response for the treatment of cancer and infectious diseases. To date, fusogenic protein-incorporated liposomes and pH-responsive polymer-modified liposomes have been used to achieve cytoplasmic delivery of antigen via membrane rupture or fusion with endosomes. Howeve...

The mechanisms associated with the cellular internalization of nanomedicines must be carefully considered when designing drug- and vaccine-delivery systems. The cellular fate and effects of nanomedicines depend to a large extent on the cell uptake routes. A self-assembled mannan nanogel is developed as a vaccination platform for antigen and adjuvant delivery. The mannan nanogel uptake by murine...

The biological applications of luminescent semiconductor quantum dots (QDs) continue to grow at a nearly unabated pace. This growth is driven, in part, by their unique photophysical and physicochemical properties which have allowed them to be used in many different roles in cellular biology including: as superior fluorophores for a wide variety of cellular labeling applications; as active platf...

INTRODUCTION Nanoparticles (NPs) are used extensively in drug delivery. They are administered through various routes in the host, and their uptake by the cellular environment has been observed in several pathways. After uptake, NPs interact with cells to different extents, depending on their size, shape, surface properties, ligands tagged to the surface and tumor architecture. Complete understa...

specific and non- specific cellular immune responses were studied in 20 amoebiasis cases and 10 controls. all the study cases and controls were indians living in varanasi, india. ten amoebic liver abscess cases were patients admitted to university hospital. ten non-invasive intestinal amoebiasis cases constituted the second study group. non-specific immune responses were studied using e-rosette...

among the drug delivery and targeting (ddt) routes, lung alveolar epithelium has been given enormous attentions in terms of the delivery of a wide range of macromolecules such as gene- or protein-based nanopharmaceuticals. however, little is known about cellular modulation of lung transport characteristics by endogenous and/or exogenous agents. thus, in the current study, impact of dexamethason...

The cellular delivery of short interfering RNA (siRNA) is a main hurdle in therapeutic drug development. Here, we describe that phosphorothioate (PTO)-derived oligonucleotides stimulate the physical cellular uptake of siRNA in trans in human cells. This is reflected by an apparent dose-dependent siRNA-mediated suppression of lamin A/C in primary human umbilical vein endothelial cells. The PTO-s...

Carbon nanotubes (CNT) can intracellulary traffic through different cellular barriers and deliver biomolecules into living cells. However, their use in plants is limited by the cellulosic wall surrounding the plant cell. Here we show that CNT with immobilized cellulase can serve as an efficient DNA delivery system for plant cells. Tracking the cellular fate of nanotubes revealed two novel pheno...

Artificial intelligence (AI) is critical for improving the quality of stem cell manufacturing and delivery. AI can assist in determining viability, effectiveness, efficacy, safety cells. Furthermore, regenerative medicine, utilized to streamline simulation model-building processes find connections between cellular activities their microenvironments. However, thoughtful consideration required mi...

Fibrin sealant has vast uses in surgical settings for both cellular and noncellular delivery. Some advantages include biocompatibility, ability to support cell attachment, controlled degradation rate. There are many clinical applications, from wound healing improving bone defects being used as an adjunct surgery. It can also serve a suitable delivery vehicle cells, steroids, antibiotics, growth...
