A new platform for drug, gene and peptide-protein delivery is emerging, under the common name of "extracellular vesicles". Extracellular vesicles (EVs) are 30-1000 nm-sized cell-derived, liposome-like vesicles. Current research on EVs as nano-delivery systems for small-molecule drugs and genetic material, reveal that these tiny, biologically-derived vesicles carry a great potential to boost the efficacy of many therapeutic protocols. Several features of EVs; from efficacy to safety, from passive to active targeting ability, the opportunity to be biologically or chemically labelled, and most importantly, their eobiotic origin make them promising candidate for development of the next generation personalized nanomedicines. The aim of this article is to provide a view on the current research in which EVs are used as drug/genetic material delivery systems. Their application areas, drug loading and targeting strategies, and biodistribution properties are discussed.

Bone serves as a fundamental structural component in the body, playing pivotal roles in support, protection, mineral supply, and hormonal regulation. However, critical-sized bone injuries have become increasingly prevalent, necessitating extensive medical interventions due to limitations in the body's capacity for self-repair. Traditional approaches, such as autografts, allografts, and xenografts, have yielded unsatisfactory results.

Background: Exosomes are extracellular vesicles, composed of a phospholipid bilayer, that are primarily derived from stem cells. The contents of exosomes can be incorporated into the tissue in which they are introduced, which presents a unique therapeutic option.
Aims: Exosomes have been investigated as a treatment for a number of medical ailments, but the literature supporting these indications is inconclusive.

Background/objectives: Prostate cancer (PCa) is characterised by its progression to a metastatic and castration-resistant phase. Prostate tumour cells release small extracellular vesicles or exosomes which are taken up by target cells and can potentially facilitate tumour growth and metastasis. The present work studies the effect of exosomes from cell lines that are representative of the different stages of the disease on the tumoral phenotype of PC3 cells.

, a Gram-negative anaerobic bacterium colonizing the intestinal mucus layer, is regarded as a promising "next-generation probiotic". There is mounting evidence that diabetes and its complications are associated with disorders of abundance. Thus, and its components, including the outer membrane protein Amuc_1100, -derived extracellular vesicles (AmEVs), and the secreted proteins P9 and Amuc_1409, are systematically summarized with respect to mechanisms of action in diabetes mellitus.

Inflammatory skin diseases comprise a group of skin conditions characterized by damage to skin function due to overactive immune responses. These disorders not only impair the barrier function of the skin but also deteriorate the quality of life and increase the risk of psychiatric issues. Here, a low-modulus phosphatidylserine-exposing microvesicle (deformed PSV, D-PSV) was produced, characterized, and evaluated for its potential therapeutic function against skin diseases.
