Bacteria have acquired multiple systems to expose proteins on their surface, release them in the extracellular environment or even inject them into a neighboring cell. Protein secretion has a high adaptive value and secreted proteins are implicated in many functions, which are often essential for bacterial fitness. Several secreted proteins or secretion machineries have been extensively studied...
BACKGROUND Podocytes are uniquely structured cells that are critical to the kidney filtration barrier. Their anatomic location on the outer side of the glomerular capillaries expose podocytes to large quantities of both plasma and urinary components and thus are reachable for drug delivery. Recent years have made clear that interference with podocyte-specific disease pathways can modulate glome...
Protein assemblies with cage-like structures are found widely in Nature a large diversity of structural properties and functionalities. These architectures provide both inspiration for biomimetic design templates bioengineering. Inspired by the native utility protein nanocage (PNC) cargo loading, transport, protection, significant effort has been put into development PNC-based biomedical applic...
Transdermal drug delivery (TDD) is a non-invasive, topical administration method for therapeutic agents. Transdermal delivery also has advantages including providing release for long periods of time, improving patient compliance, and generally being inexpensive. Despite these advantages, the use of TDD has been limited by innate barrier functions of the skin. Only small (<500 Da), lipophilic mo...
Allosteric drugs are usually more specific and have fewer side effects than orthosteric drugs targeting the same protein. Here, we overview the current knowledge on allosteric signal transmission from the network point of view, and show that most intra-protein conformational changes may be dynamically transmitted across protein-protein interaction and signaling networks of the cell. Allo-networ...
Objective(s): P-glycoprotein (P-gp) is an efflux protein, the overexpression of which has been associated with multidrug resistance in various cancers. Although siRNA delivery to reverse P-gp expression may be promising for sensitizing of tumor cells to cytotoxic drugs, the therapeutic use of siRNA requires effective carriers that can deliver siRNA intracellularly with minimal toxicity on targe...
Introduction: Among several tuberculosis vaccine candidates for replacement of BCG, ESAT-6 protein has a special role. Since mycobacterium tuberculosis infection most often attacks the lungs, intranasal rout can be regarded as appropriate methods for tuberculosis vaccines and drug delivery. One of the appropriate systems for intranasal vaccine delivery is using biodegradable nanoparticles. Amon...
