Homovanilowy

Homovanilowy, also known as homovanillic acid (HVA), is a significant metabolite of dopamine, a neurotransmitter involved in various functions of the central nervous system. It is primarily produced through the enzymatic breakdown of dopamine by monoamine oxidase (MAO) and aldehyde dehydrogenase. Homovanilowy is widely used in scientific research and clinical diagnostics as an indicator of dopaminergic activity in the brain and peripheral tissues.

In clinical contexts, elevated levels of homovanilowy in cerebrospinal fluid (CSF) or plasma can be associated with certain neurological and psychiatric disorders, such as Parkinson’s disease, schizophrenia, and neuroblastoma. Conversely, decreased levels may be seen in conditions characterized by reduced dopaminergic function. Measurement of homovanilowy is often performed via high-performance liquid chromatography (HPLC) coupled with electrochemical detection, providing valuable insights into dopaminergic system status.

Homovanilowy also plays a role in pharmacology as a marker for the effectiveness of medications targeting dopamine pathways, such as antipsychotics or treatments for Parkinson’s disease. It is vital for understanding the biochemical basis of disorders involving dopamine dysregulation and for monitoring treatment responses.

Overall, homovanilowy serves as a crucial biomarker in both research and clinical practice, aiding in the diagnosis, understanding, and management of various neuropsychiatric and neurodegenerative conditions.
