Study analyzes the viability of new nanomolecule as drug delivery vehicle.
A new study by the University of Barcelona has analyzed the viability of a new nanomolecule as drug delivery vehicle.
The results, published in the journal Colloids and Surfaces B: Biointerfaces, show that liposomes designed by researchers are able to transport and deliver an anticancer drug that has been used as a model inside the cells.
The study included the participation of researchers from the University of Barcelona faculties of Biology, Physics and Pharmacy and Food Sciences, as well as researchers from the Scientific and Technological Centers of the UB (CCiTUB), the Institute of Nanoscience and Nanotechnology of the UB (IN2UB) and from the Institute for Bioengineering of Catalonia (IBEC).

Potential drug delivery system one of The challenges of turning liposomes into Drug delivery vehicles is finding out How they interact with cell membranes And what basic mechanism adsorption Fusion or endocytosis or a combination Of these three is involved in the Integration of liposomes by cells the Interactions between liposomes and the Cell membrane can be extremely different Depending on the nature of the cell Membrane and the lipidic composition of Liposomes the researchers note the Liposomes designed by the up team are Small lipid spheres with a composition Similar to that of the cell they want to Treat this similarity eases its Incorporation and the drug delivery Inside the cell notes Oscar Dominic High-end 2ub member and one of the Researchers that took part in the study Study in cell cultures this study is the Continuation of a previous study carried Out by the same research team which Analyzed the few Fusion mechanisms of Liposomes using a simplified model that Copied the membrane of hella cells a Type of culture cells which are widely Used in scientific research the membrane Of hella cells is more complex than the Model we used in the previous study now We have used real cell cultures in order To obtain a better view of the Interaction mechanism of our liposomes
The researchers say to study the Interaction between the liposomes and The cell membrane and to assess the Integration of these nanomolecules the Researchers combine two techniques on The one hand they used confocal Fluorescence which allows them to see Fluorescent molecules inside the cell Then the liposomes encapsulated calcane A fluorescent eye to see whether the Nanomolecule and its content were Entering the cells on the other hand the Researchers used the atomic Force Microscopy technique to see the physical Chemical changes of the cell surface and Assess the stiffness of the cell Membrane and the presence of liposomes The interaction of the liposomes Designed by the researchers affirmed the Results obtained with model membranes And it shows the capacity of the Formulation of these nanomolecules as a Potential nanotransporter we show that The lipid composition enables a delivery Of the liposome content inside the cell As well as the effect of the Philippodius small flagella of the cell In easing the arrival of liposomes at The cell membrane adds Oscar Dominic a Test with an anti-cancer drug to Validate the capacity of these liposomes As a drug delivery system the Researchers encapsulated Methotrexate And immunosuppressive drug used and the
Treatment of several oncologic Inflammatory and autoimmune pathologies We could show that our liposomes are Ideal for delivering this model molecule Which we know can eliminate cancer cells Oscar Dominic researcher these results Open the door to Future studies with Other molecules and cell types our Interest would be to extend the Methodology to other types of cells or Even tissues to show the viability of The analysis as well as to use other Therapeutical molecules encapsulated in Liposomes says Dominic moreover he adds The two techniques we apply during the Study allowed us to obtain results in a Fast and minimally invasive way which in The future could be indicators of the Good functioning of a drug against Cancer cells Bata Carreras Al 2022 on The uptake of kashanic liposomes by Cells from changes in elasticity to Internalization colloids and surfaces Biointerfaces doi.org 10.1016 J Cole surf.202 2.112968 Foreign [Music]
