Resumen

Parkinson's disease is caused by the death process of dopaminergic neurons in the substantia nigra, pars compacta of the brain. Although its etiology is unknown, the finding of Lewy bodies, formed by alpha-synuclein, in the intestine suggests a source of microbial production that travels to the central nervous system, mainly through the pneumogastric nerve. To understand how the microbiota-gut-brain axis works and influences a healthy person or person with Parkinson's disease, a systematic review of scientific articles from the last five years was carried out in the Scopus database. It has been shown that the signaling network that regulates the microbiota-gut-brain axis in a bidirectional communication network is present during the neurodevelopment of the individual and at the onset of Parkinson's disease, therefore, the microbiota represents the entry point of internal factors that disrupt communication and neurological dysfunction. As the diversity of the microbiota changes at various stages of the individual's development for multiple reasons, such as diet, hygiene patterns, interaction with animals and parasites, and medication, among other factors; it is necessary to know the state of the current microbiota, understand its function in the enteric nervous system and its influence on the central nervous system, especially if it is the etiopathogenesis of neurodegenerative diseases. The discovery of diagnostic biomarkers and neuroprotective therapies holds the promise of significantly improving the quality of life for individuals with Parkinson's disease.
