Rita Levi-Montalcini's 1953 discovery of nerve growth factor (NGF) in mouse sarcoma tumors marked a groundbreaking moment in neuroscience. NGF, a key signaling molecule, became the first identified neurotrophic factor, influencing the growth, differentiation, and survival of neurons in both peripheral and central nervous systems. NGF and related neurotrophic factors hold therapeutic potential for various neurological disorders, such as Alzheimer's Disease, Parkinson's Disease, Huntington's Disease, amyotrophic lateral sclerosis, spinal cord injuries, neuropathies, traumatic brain injuries, and stroke. However, despite promising in vitro studies and animal models findings, NGF efficacy in patients remains unproven. Indeed, its use as a therapeutic agent faces challenges in delivery and clinical translation. This review delves into these challenges, exploring ongoing research on refined delivery methods, dosages, and safety profiles. Innovative strategies, including molecular mimicking, combination therapies, gene therapy, and coupling with neuromodulation techniques like transcranial magnetic stimulation and vagal nerve stimulation, are discussed. Incorporating nerve growth factor (NGF) into a comprehensive strategy may prove beneficial, particularly in non-neurodegenerative conditions such as stroke, trauma, and neuropathies. In these instances, NGF holds promise for promoting tissue regeneration and repair. Challenges persist in addressing the complexity of neurodegenerative pathologies for a combined therapeutic approach.
