What is Gene Therapy?\u00a0<\/strong><\/h2>\n

 <\/p>\n

Gene therapy is an advanced medical technique that involves modifying or replacing defective genes to treat or prevent diseases. It works by introducing a therapeutic gene into a patient’s cells to correct genetic treatment is rapidly transforming modern medicine by targeting the root cause of diseases rather than just managing symptoms.\u00a0<\/span><\/p>\n

History and Development of Gene Therapy\u00a0<\/strong><\/h2>\n

Early Research in Genetic Treatment\u00a0<\/b><\/h3>\n

The concept of gene therapy emerged in the 1970s when scientists began understanding DNA and gene functions. Early experiments focused on theoretical models of replacing faulty genes.\u00a0<\/span><\/p>\n

First Successful Gene Therapy Trials\u00a0<\/b><\/h3>\n

The first successful human gene therapy trial was conducted in 1990 to treat a rare immune disorder called ADA-SCID, marking a milestone in medical science.\u00a0<\/span><\/p>\n

Modern Advances in Gene Editing\u00a0<\/b><\/h3>\n

Recent breakthroughs like CRISPR technology have revolutionised gene therapy-type approaches, making gene editing more precise, efficient and accessible.\u00a0<\/span><\/p>\n

Types of Gene Therapy\u00a0<\/strong><\/h2>\n

Somatic Gene Therapy\u00a0<\/b><\/h3>\n

This involves modifying genes in non-reproductive cells. The changes affect only the patient and are not passed to future generations.\u00a0<\/span><\/p>\n

Germline Gene Therapy\u00a0<\/b><\/h3>\n

Germline therapy targets reproductive cells (sperm or eggs), meaning changes can be inherited. This approach is controversial and largely restricted due to ethical concerns.\u00a0<\/span><\/p>\n

In Vivo Gene Therapy\u00a0<\/b><\/h3>\n

Genes are delivered directly into the patient\u2019s body using vectors.\u00a0<\/span><\/p>\n

Ex Vivo Gene Therapy\u00a0<\/b><\/h3>\n

Cells are modified outside the body and then reintroduced into the patient.\u00a0<\/span><\/p>\n

How Gene Therapy Works\u00a0<\/strong><\/h2>\n

Role of Therapeutic Genes\u00a0<\/b><\/h3>\n

A therapeutic gene replaces or repairs a faculty gene responsible for disease, restoring normal cellular function.\u00a0<\/span><\/p>\n
