liposzómás

Liposzómás, also known as liposomes, are microscopic vesicles composed of a phospholipid bilayer that can encapsulate a wide variety of molecules, including drugs, genetic material, and other therapeutic agents. They are used in various biomedical applications, including drug delivery, gene therapy, and vaccine development.

Liposomes were first discovered in the 1960s and have since become a popular tool in the field of drug delivery. They can be designed to target specific cells or tissues, release their payload in a controlled manner, and reduce the side effects associated with traditional drug delivery methods. Liposomes can also be used to transport genetic material, such as DNA or RNA, into cells, making them a potential tool for gene therapy.

The structure of liposomes consists of a lipid bilayer, with the hydrophilic heads facing outwards and the hydrophobic tails facing inwards. The bilayer can be composed of various lipids, depending on the desired properties of the liposome. Liposomes can be either small, unilamellar vesicles (SUVs) or large, multilamellar vesicles (LUVs), depending on their intended application.

Liposomes have been used in a number of research and clinical applications, including the treatment of cancer, infectious diseases, and genetic disorders. However, there are also potential risks associated with the use of liposomes, including lipidosis, which is a condition characterized by the accumulation of lipids in tissues. Further research is needed to fully understand the benefits and risks of liposome-mediated drug delivery.
