Ebook "Endosomes" represent a fascinating interconnected network of thousands of vesicles that transport various cargoes, mainly proteins and lipids, to distant cellular destinations. How endosomes function, what coordinates the molecular determinants at each step of their dynamic life cycle and what their biological and medical relevance is, are among the questions addressed in this book.

In ebook "Peptide and protein interaction with membrane systems: Applications to antimicrobial therapy and protein drug delivery" the study of peptide-membrane interactions has been carried out using model membranes. It has been shown, indeed, that peptides feature the same activity on these systems. The most common membrane model is represented by lipid vesicles (liposomes), a simple but realistic system for physical and chemical studies of a variety of phenomena.

Successful treatment of skin infections requires eradication of biofilms found in up to 90 % of all chronic wounds, causing delayed healing and increased morbidity. We hypothesized that chitosan hydrogel boosts the activity of liposomally-associated membrane active antimicrobials (MAA) and could potentially improve bacterial and biofilm eradication.

Exosomes, internal proteins, lipids, and nucleic acids coated by phospholipid bilayer membranes, are one type of small extracellular vesicles, which can mediate cell-cell communication. In recent years, exosomes have gained considerable scientific interest due to their widely applied prospect in the diagnosis and therapeutics of human and animal diseases.

Nematode sperm have unique and highly diverged morphology and molecular biology. In particular, nematode sperm contain subcellular vesicles known as membranous organelles that are necessary for male fertility, yet play a still unknown role in overall sperm function. Here we take a novel proteomic approach to characterize the functional protein complement of membranous organelles in two Caenorhabditis species: C. elegans and C. remanei.

SNAP-25 protein is contributory to plasma membrane and synaptic vesicle fusions that are critical points in neurotransmission. SNAP-25 gene is associated with behavioral symptoms, personality and psychological disorders. In addition, SNAP-25 protein can be related to different neurotransmitter functions due to its association with vesicle membrane transition and fusion.

Outer membrane vesicles (OMV) are closed spheroid vesicles with size ranging between 20–500 nm produced by both Gram negative and Gram positive bacteria. OMV are formed by the blebbing and pinching off segments of bacterial outer membrane. They are composed of lipopolysaccharide (LPS), glycerophospholipids, outer membrane proteins (OMPs), and periplasmic components.

The OsSec18 complex interacts with P0(P1-P2)2 to regulate vacuolar morphology in rice endosperm cell
Sec18p/N-ethylmaleimide-sensitive factor (NSF) is a conserved eukaryotic ATPase, which primarily functions in vesicle membrane fusion from yeast to human. However, the function of the OsSec18 gene, a homologue of NSF in rice, remains unknown.

During the last few years, membrane vesicles (as exovesicles) have emerged as potential nanocarriers for therapeutic applications. They are receiving attention due to their proteo-lipid nature, size, biocompatibility and biodegradability. In this work, we investigated the potential use of isolated root plasma membrane vesicles from broccoli plants as nanocarriers. For that, the entrapment efficiency and integrity of the vesicles were determined. Also, the delivery of keratinocytes and penetrability through skin were studied.

The present study investigates the entrapment of terbinafine hydrochloride (TH) in ethosomal vesicles via unsonicated and sonication method. Carbopol 934P was incorporated in the best formulation, F6, obtained by sonication method. The formulated ethosomal gel obtained as such i.e. F6* was exploited to achieve a zero order release profile of TH. The composition includes phospholipid, ethanol and propylene glycol. Drug entrapment efficiency (DEE), invitro and ex-vivo drug diffusion studies, FT-IR and stability studies of the prepared ethosomes were investigated.
