What are gene and cell therapies?

Gene and cell therapies are advanced medical treatments aimed at stopping or slowing disease progression. Gene therapy involves replacing or modifying faulty genes with corrected versions, while cell therapy replaces or repairs damaged cells. Gene editing, utilizing tools like CRISPR, enable targeted and programmable repair of damaged gene products. Mass General Brigham offers a range of FDA-approved gene and cell therapy treatments for various medical conditions, including certain types of cancer, hereditary diseases, and blood disorders.

What are gene and cell therapies?

Types of therapies

Many diseases can involve a genetic component — a missing gene, multiple copies of a gene, or a gene that is structurally defective. Gene therapy is the process of replacing or modifying genes to correct a deficiency, sometimes by altering the DNA sequence of the target gene or by modifying expression of a gene by turning it off or on. Gene therapy can have an especially profound effect in congenital diseases where the disease is associated with malfunction of a single gene. Researchers are working to identify such genes and develop therapies to replace or modify genes.

Cell therapy involves replacing or modifying cells to treat disease. Cell therapy can use cells from another person (allogenic) or the person’s own cells (autologous), which may or may not be genetically altered.

Autologous, modified cell therapy is personalized to treat an individual’s condition where scientists take the person’s own cells and genetically change them outside the body, expand the number of modified cells, and then reinfuse these modified cells to produce a therapeutic benefit. Such therapies alter the patient's cells so their immune system can now target and destroy previously stealth diseased cells.

Examples of cells that are modified to treat disease include T-cells (commercialized as chimeric antigen receptor T cells; CAR-T cells), B-cells, Natural Killer (NK) cells, Tumor Infiltrating Lymphocytes (TILs), and Dendritic Cells (DCs).

Gene editing is the modification of a cell’s DNA with great precision using tools, such as CRISPR-based biotechnologies, that enable programmable and targeted repair of damaged gene products.

Marcela Maus, MD, PhD

Dr. Maus and her research team design and evaluate next generation genetically modified (CAR) T cells as immunotherapy in patients with cancer. Using the immune system as treatment has the potential to induce long-term, durable remissions, and perhaps even cures for some patients. “We’re effectively hacking the immune system so patients’ own bodies can fight their disease,” says Dr. Maus.
