Special Issue Information

Dear Colleagues,

Liposomes are small spherical vesicular structures composed of one or more phospholipid bilayers. Liposomal drug delivery systems possess specific features, including nano size, biodegradability, hydrophobic/hydrophilic characteristics, biocompatibility, and low or no toxicity and immunogenicity, which can all lead to considerable efficacy in treating various types of diseases. The rationale for developing liposomal-based drug delivery systems is to improve the therapeutic efficacy of drugs by reducing drug toxicity, improving drug solubility and stability, enhancing drug delivery to specific targets, and/or increasing their permeation across biological barriers. The diverse applications of liposomes as carriers for the delivery of drugs and other molecules have been attributed to the physicochemical and biophysical characteristics of the liposomal membrane and especially of the vesicle surface.

This Special Issue welcomes studies that include (but are not limited to) all aspects of liposomal drug delivery systems including their design, development, and characterizations as well as their pharmacodynamic and pharmacokinetic properties and their use as strategies for the prevention or treatment of medical conditions such as cancer, infection, inflammation, oxidant-induced tissue injuries, dermatological diseases, etc. Original research articles and comprehensive reviews are especially welcome.

The purpose of the present study was to investigate the anti-staphylococcal activity of liposomal daptomycin against four biofilm-producing S. aureus and S. epidermidis clinical strains, three of which are methicillin-resistant. Neutral and negatively charged daptomycin-loaded liposomes were prepared using three methods, namely, thin-film hydration (TFH), a dehydration–rehydration vesicle (DRV) method, and microfluidic mixing (MM); moreover, they were characterized for drug encapsulation (EE%), size distribution, zeta-potential, vesicle stability, drug release, and drug integrity. Interestingly, whilst drug loading in THF and DRV nanosized (by extrusion) vesicles was around 30–35, very low loading (~4%) was possible in MM vesicles, requiring further explanatory investigations. Liposomal encapsulation protected daptomycin from degradation and preserved its bioactivity. Biofilm mass (crystal violet, CV), biofilm viability (MTT), and growth curve (GC) assays evaluated the antimicrobial activity of neutral and negatively charged daptomycin-liposomes towards planktonic bacteria and biofilms. Neutral liposomes exhibited dramatically enhanced inhibition of bacterial growth (compared to the free drug) for all species studied, while negatively charged liposomes were totally inactive. Biofilm prevention and treatment studies revealed high antibiofilm activity of liposomal daptomycin. Neutral liposomes were more active for prevention and negative charge ones for treating established biofilms. Planktonic bacteria as well as the matured biofilms of low daptomycin-susceptible, methicillin-resistant Staphylococcus aureus (MRSA) and Staphylococcus epidermidis (MRSE) strains were almost completely eradicated by liposomal-daptomycin, indicating the need for their further exploration as antimicrobial therapeutics.
