Neurturin (NRTN), a member of the glial cell line-derived neurotrophic factor (GDNF) family, is a secreted protein critical for the development and maintenance of the nervous system. It primarily signals through the RET receptor tyrosine kinase in complex with a glycosylphosphatidylinositol (GPI)-anchored co-receptor, GFRα2. NRTN supports the survival and differentiation of various neuronal populations, including dopaminergic, enteric, and sensory neurons, making it a potential therapeutic target for neurodegenerative diseases like Parkinson’s disease and enteric neuropathies.
Recombinant NRTN protein is engineered using biotechnological methods, often expressed in *E. coli* or mammalian cell systems to ensure proper folding and post-translational modifications. Its production involves cloning the NRTN gene into expression vectors, followed by purification via chromatography techniques. The recombinant form retains the biological activity of native NRTN, enabling research and clinical applications.
Preclinical studies highlight its neuroprotective effects in animal models of Parkinson’s disease, where it enhances dopaminergic neuron survival and mitigates motor deficits. However, challenges such as poor blood-brain barrier penetration and short half-life have spurred innovations in delivery systems, including viral vectors, encapsulated cell therapies, or conjugation with carrier molecules.
Despite promising results, clinical translation remains limited. Early-phase trials demonstrated mixed outcomes, partly due to insufficient target engagement or suboptimal dosing. Ongoing research focuses on optimizing delivery routes, dosing regimens, and combination therapies. Beyond neurodegeneration, NRTN is explored for treating diabetes (via pancreatic β-cell protection) and chronic pain. Safety profiles and long-term efficacy require further validation to advance therapeutic development.
