Although the incidence of PD is twofold higher in males than in females, the female sex is associated with higher mortality and more rapid disease progression (Baldereschi et al., 2000; Dahodwala et al., 2018). Some several strengths and limitations of this study need to be acknowledged. . The contribution of astrocytes and microglia to traumatic brain injury. First, sequencing adapters were removed from sequencing reads using cutadapt v1.9. Scale bars: 100 m. For example, Centella asiatica and Centella asiatica glycosides found in Centella asiatica have been shown to have neuroprotective effects in stroke models, reducing cytotoxic damage and microglia activation (Chen et al., 2014).

In the meantime, to ensure continued support, we are displaying the site without styles However, the findings in Asia differ from those in the West, with no significant differences in -diversity between males and females documented in a Japanese study (Takagi et al., 2019). However, our study has some weaknesses: (i) It was designed as a pilot study with a small sample size. Importantly, our study identified significant differences in the relative abundance of gut microbiota at the genus level between male and female PD patients. Professor Paolo Calabresi said: "Our research team is involved in a clinical trial to test whether intensive exercise can identify new markers to monitor the disease progression slowing in early-stage patients and the profile of the progression of the disease.

Together, these data emphasize the importance of the initial inflammatory response to surgical injury in the differential survival of cellular components of the graft, and suggest that co-transplanting autologous Treg cells effectively reduces the needle-trauma-induced death of mDANs, providing a potential strategy to achieve better clinical outcomes for cell therapy in Parkinsons disease. The work by Siani et al. The study "Intensive exercise ameliorates motor and cognitive symptoms in experimental Parkinson's disease by restoring striatal synaptic plasticity" is published in the journal Science Advances. In female patients, the relative abundance of Propionicicella was decreased and Escherichia, Escherichia_coli, and Lachnospiraceae were predominant. (D) Cladogram generated by LEfSe analysis. The increase in the abundance of Enterobacteriaceae was considered essential in intestinal flora disorders associated with PD (Li et al., 2017).

Parkinson's disease: etiopathogenesis and treatment Although some of the female patients in our study were overweight, the collected data do not prove the notion that changes in gut microbiota in PD patients of different genders are affected by BMI values; a larger sample size is needed to explore the relationship between BMI and intestinal flora female PD patients.
