What is gene therapy and can it help with Parkinson’s?

Gene therapy is an innovative treatment approach involving the introduction of DNA into cells to alter protein production. It holds promise for improving symptoms or even curing diseases, including Parkinson’s disease (PD). Researchers have successfully used gene therapy to treat certain rare genetic disorders by introducing healthy genes into patients' cells, allowing them to produce healthy proteins. However, applying gene therapy to complex diseases like PD is more challenging. Various gene therapy strategies are being explored in clinical trials to treat PD. These include increasing dopamine production by introducing genes for enzymes involved in its synthesis, supporting the survival of dopamine neurons by introducing genes for neurotrophic factors, resetting abnormal brain circuitry by increasing the production of GABA, and counteracting genetic mutations that contribute to PD. While some trials have demonstrated improvements, larger trials are needed before these therapies can be clinically approved. Ongoing research and trials continue to advance the potential of gene therapy for PD, and the results are eagerly awaited.
