Consequently, its therapeutic modulation could help in chronic heart failure by promoting improved cardiac output and reducing symptoms. These effects have driven research into developing adrenomedullin analogs or mimetics as potential anti-hypertensive agents. Neuroprotective applications are another significant area for therapeutic exploitation. The ability of adrenomedullin to support neuronal survival, promote neurogenesis, and protect against oxidative stress holds potential for addressing neurodegenerative diseases such as Alzheimer’s and Parkinson’s disease. Therapies based on adrenomedullin could help mitigate neuronal loss, preserve cognitive function, and slow disease progression in affected individuals. Moreover, in stroke or traumatic brain injury, adrenomedullin-based interventions might enhance recovery by protecting neurons and supporting brain repair mechanisms.

In oncology, the role of adrenomedullin in tumor progression through angiogenesis presents a dual therapeutic challenge and opportunity. While its angiogenic effects could be detrimental by supporting tumor growth, understanding its regulatory mechanisms allows for the development of therapies that could inhibit its pro-tumorigenic activity. Inhibition of adrenomedullin signaling or function could thus offer a novel therapeutic pathway in cancers driven by angiogenesis. This requires careful modulation to avoid systemic vascular side effects due to its role in normal physiological angiogenesis. Besides malignant conditions, the immunomodulatory effects of adrenomedullin offer therapeutic potential in inflammatory and autoimmune diseases. By modulating adrenomedullin levels or mimic its activity, it may be possible to reduce excessive inflammatory responses and improve disease outcomes in conditions like rheumatoid arthritis or inflammatory bowel disease.
