Liposomes in Gene Editing

Liposomes form spherical structures with lipid bilayers to contain a broad spectrum of bioactive compounds such as nucleic acids and proteins as well as small molecules. Liposomes serve as essential delivery vehicles for gene-editing tools including CRISPR-Cas9 components as well as small guide RNAs (sgRNA) and plasmid DNA which reach target cells effectively while maintaining low toxicity levels. These versatile systems can deliver both large and small genetic materials making them a robust platform for numerous gene editing technologies. Liposomes have several advantages in gene delivery, including:

  • Reduced Immunogenicity: Liposomes can shield the cargo from immune recognition, ensuring efficient delivery to the target tissue.
  • Controlled Release: Liposomes can be engineered to release their payload at specific times or in response to external triggers, improving the accuracy of gene delivery.
  • Targeted Delivery: Liposomal formulations can be modified to target specific cell types, minimizing off-target effects and enhancing therapeutic efficacy.

Supplementary Knowledges: Gene Editing

What is the process of gene editing?

Gene editing is a technique used to alter the DNA within a living organism's cells. The process typically involves introducing precise changes to the genetic code, such as adding, deleting, or modifying specific genes. The most common methods for gene editing involve the use of molecular tools that target and cut the DNA at specific locations, allowing for the insertion or removal of genetic material.

What tool is used for gene editing?

The most widely used tool for gene editing is the CRISPR/Cas9 system. CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) is a naturally occurring defense mechanism in bacteria, which has been harnessed for gene editing. The Cas9 protein, guided by RNA molecules, locates and cuts the DNA at specific sites, allowing researchers to make precise modifications to genes.

What are the methods of delivery of CRISPR?

There are several methods for delivering CRISPR/Cas9 components into cells, including liposomal delivery, viral vectors, electroporation, and microinjection. Liposomes, which are lipid-based nanoparticles, are commonly used for their ability to encapsulate the CRISPR system and facilitate cell entry. Viral vectors can also be employed to introduce CRISPR into cells, while electroporation uses an electrical field to permeabilize cell membranes, and microinjection directly injects CRISPR components into the cell.
