Cell and Gene Therapy

Cell and Gene Therapy represent ground-breaking approaches in medicine that harness the potential of cells and genetic material to treat diseases at their root causes. These therapies offer promising avenues for treating a wide range of disorders, including genetic diseases, cancer, and degenerative conditions, by targeting the underlying molecular mechanisms responsible for the disease pathology. Cell therapy involves the transplantation or modification of cells to restore or enhance cellular function in diseased tissues or organs. This may involve the infusion of healthy donor cells, such as hematopoietic stem cells for treating blood disorders like leukemia, or the engineering of patient's own cells to correct genetic defects or enhance therapeutic properties. For example, chimeric antigen receptor (CAR) T-cell therapy genetically modifies a patient's own immune cells to recognize and kill cancer cells, leading to remarkable responses in certain types of leukemia and lymphoma. Gene therapy, on the other hand, involves the delivery of therapeutic genes into target cells to correct or modulate gene expression, either by replacing defective genes, introducing functional genes, or silencing disease-causing genes. This can be achieved using viral vectors, such as adeno-associated viruses (AAVs) or lentiviruses, or non-viral methods, such as lipid nanoparticles or naked DNA/RNA. Gene therapy holds promise for treating monogenic disorders, such as cystic fibrosis and muscular dystrophy, as well as complex diseases like cancer and neurodegenerative disorders.
