Exosome-based Delivery System Development
Exosomes, small extracellular vesicles ranging from 40 to 150 nm in diameter, play a crucial role in intercellular communication and are emerging as promising vectors for drug delivery, particularly in the treatment of brain tumors. Alfa Cytology specializes in the development and optimization of exosome-based delivery systems for brain tumors therapy.
Introduction to Exosome-Based Delivery Systems for Brain Tumors
The BBB is a selective barrier that restricts the passage of many therapeutic agents, leading to challenges in effectively treating brain tumors. Traditional drug delivery methods often result in suboptimal therapeutic concentrations at the tumor site and significant systemic toxicity. Exosomes, due to their biocompatibility, low immunogenicity, and ability to encapsulate a variety of therapeutic agents—including proteins, nucleic acids, and small molecules—offer a novel solution to these challenges. brain tumor treatment.

Recent studies have demonstrated that exosomes can be engineered to carry specific therapeutic agents, enhancing their accumulation in tumor tissues while minimizing off-target effects. For instance, exosomes derived from mesenchymal stem cells have shown enhanced delivery of anticancer drugs directly to glioblastoma cells, resulting in improved therapeutic efficacy and reduced side effects compared to conventional therapies. This targeted approach not only improves the treatment outcomes for patients but also paves the way for more personalized medicine strategies in oncology.
