Evaluation of cytochalasin B-induced membrane vesicles fusion specificity with target cells

A paper was published in BioMed Research International.

As team leader Marina Gomzikova explains, "The understanding of interaction between cytochalasin B-induced microvesicles (CIMVs) and target cells can help create specific vectors for anti-tumor drug delivery. This will allow for the decrease of toxic effect on normal cells and the enhancement of therapeutic results."

In this new research, the authors conducted a study of specificity of vesicle fusion with target cells. They evaluated the contribution of endocytosis, i. e. active transport of molecules into cells via the folding of plasma membrane. It was found out that proteinase K treatment effectively inhibited the internalization of induced membrane vesicles into target cells. Inhibition of interaction of membrane proteins of CIMVS with surface proteins of target cells is the biggest influence on the effectiveness of internalization of CIMVs.

Professor Albert Rizvanov, Head of Gene and Cell Technologies Lab, adds that this particular research is a very good example of an inquiry into biomimetic technology. In this case, it's the introduction of artificial microvesicles which are very similar to natural ones.

As the research has shown so far, CIMVs can become the basis for a new class of effective and safe anti-tumor medications.
