ing exogenous nucleotides into mammalian cells is critical for both basic sciences and clinical applications, such as gene therapy. Among various methods for gene transfection, lipofection using cationic liposomes is considered to be a promising way to deliver a foreign gene to target cells. Although many kinds of cationic liposomes have been developed for lipofection, further studies are still...

Specific delivery of therapeutic agents to solid tumors and their bioavailability at the target site are the most clinically important and challenging goals in cancer therapy. Liposomes are promising nanocarriers and have been well investigated for cancer therapy. In spite of preferred accumulation in tumors via the enhanced permeability and retention (EPR) effect, inefficient drug release at t...

objective(s): drug delivery via mucosal routes has been confirmed to be effective in inducing strong immune responses. liposomes could enhance immune responses and mucoadhesive potentials, make them useful mucosal drug delivery systems. coating of liposomes by mucoadhesive polymers succeeded in enhancing immune responses. our studies aim at preparation and characterization of trimethylchitosan-...

Discoidin I, a soluble lectin synthesized by aggregating Dictyostelium discoideum and implicated in their adhesion to the substratum, is localized in multilamellar bodies both intracellularly and upon externalization. These structures also contain a glycoconjugate that binds discoidin I. The multilamellar bodies apparently serve to package the lectin for externalization, and may then gradually ...

BACKGROUND Staphylococcus aureus in its biofilm form has been associated with recalcitrant chronic rhinosinusitis with significant resistance to conventional therapies. This study aims to determine if liposomal-encapsulation of a precursor of the naturally occurring antimicrobial nitric oxide (NO) enhances its desired anti-biofilm effects against S. aureus, in the hope that improving its effica...

intranasal vaccination is particularly a striking route for mucosal immunization, due to the ease of administration and the induction of both mucosal and humoral immunity. however, soluble antigens (ag) are not sufficiently taken up after the nasal administration and need to be co-administered with adjuvants, penetration enhancers or encapsulated in particles. so, in this study, tetanus toxoid ...

liposomes have attracted great interest as efficient carriers for nutrients, drugs and other bioactive agents as well as ideal models for biological membranes. this article intends to provide an overview of liposomes and nanoliposomes definition as well as their properties and preparation methods. also it elaborates on various applications of nanoliposomes in nanotherapy including diagnostics, ...

Understanding the structure of solid supported lipid multilayers is crucial to their application as a platform for novel materials. Conventionally, they are prepared from drop casting or spin coating of lipids dissolved in organic solvents, and lipid multilayers prepared from aqueous media and their structural characterisation have not been reported previously, due to their extremely low lipid ...
