Abstract
There are more than 3,500 genes that are being linked to hereditary diseases or correlated
with an elevated risk of certain illnesses. As an alternative to conventional treatments with small
molecule drugs, gene therapy has arisen as an effective treatment with the potential to not just alleviate
disease conditions but also cure them completely. In order for these treatment regimens to
work, genes or editing tools intended to correct diseased genetic material must be efficiently delivered
to target sites. There have been many techniques developed to achieve such a goal. In this article,
we systematically review a variety of gene delivery and therapy methods that include physical
methods, chemical and biochemical methods, viral methods, and genome editing. We discuss their
historical discovery, mechanisms, advantages, limitations, safety, and perspectives.
Keywords:
