Gene and cell therapies are innovative medical treatments designed to address diseases at their underlying biological cause. Unlike traditional therapies that primarily manage symptoms, these approaches aim to modify genes or use living cells to repair, replace, or restore normal function. They are increasingly used for certain inherited disorders, blood diseases, immune disorders, and some types of cancer. Ongoing research continues to expand their potential across many medical conditions. Careful patient selection, specialized treatment centers, and long-term monitoring are essential for maximizing benefits and ensuring safety.
Gene therapy involves changing or adding genetic material inside a person's cells to help treat or prevent disease.
Cell therapy involves introducing, modifying, or replacing living cells to restore normal function or help the immune system fight disease.
Although often discussed together, gene therapy and cell therapy are distinct treatment approaches and may sometimes be combined.
Gene therapy may treat disease by:
Treatment may be delivered directly into the body or by modifying cells outside the body before they are returned to the patient.
Cell therapies use living cells to repair damaged tissues or improve immune function.
Examples include:
The type of cells used depends on the condition being treated.
Gene and cell therapies are approved or being studied for a growing number of diseases, including:
Research continues to evaluate these therapies for additional cancers and rare diseases.
For eligible patients, gene and cell therapies may offer:
Benefits vary depending on the specific disease and therapy.
As with any advanced medical treatment, risks may occur.
Potential side effects include:
Healthcare teams closely monitor patients before, during, and after treatment.
Long-term follow-up is an important part of gene and cell therapy.
Monitoring may include:
Some therapies require follow-up for several years.
Eligibility depends on several factors, including:
Specialized medical centers evaluate whether these treatments are appropriate for each individual.
Gene and cell therapies represent a major advancement in modern medicine by targeting diseases at the genetic or cellular level. These innovative treatments have expanded care for certain inherited disorders, blood diseases, immune conditions, and cancers, while ongoing research continues to broaden their applications.
