The pathogenesis of PD remains incompletely understood, and disease-modifying therapies are lacking. Emerging evidence suggests that gut microbiota and their metabolites influence both intestinal and central nervous system (CNS) functions via the microbiota-gut-brain axis (MGBA). Recent studies have identified dysbiosis in the gut microbiota of PD patients, which may contribute to disease progression through two primary mechanisms: First, increased intestinal permeability, allowing pro-inflammatory factors and microbial metabolites to affect the enteric nervous system (ENS) and subsequently spread to the CNS via the vagal neurons; Secondly, disruption of the Blood\u2013Brain barrier (BBB), leading to neuroinflammation and aberrant\n                      <jats:italic>\u03b1<\/jats:italic>\n                      -syn aggregation, ultimately resulting in dopaminergic neuron degeneration. These findings underscore the critical role of the MGBA in PD pathogenesis, which makes gut microbiota modulation a promising therapeutic target.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Highlights<\/jats:title>\n                    <jats:p>This review synthesizes current knowledge on gut microbiota alterations in PD and evaluates the potential of fecal microbiota transplantation (FMT) as an adjunctive therapy to alleviate motor and non-motor symptoms and slow disease progression.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>FMT has demonstrated efficacy in ameliorating PD symptoms via the MGBA.
