While mitochondrial dysfunction is a well-studied phenomenon in the substantia nigra, which is selectively vulnerable in Parkinson's disease and some models thereof, less information is available in other brain regions that are also affected by synuclein pathology.Therefore, we sought to test the hypothesis that early α-synuclein pathology causes mitochondrial dysfunction and that this effect might be exacerbated in conditions of increased vulnerability in affected brain regions, such as the amygdala.We combined a model of intracerebral α-synuclein pathology seeding with chronic glucocorticoid treatment, which models non-motor symptoms of Parkinson's disease and affects amygdala physiology. We measured mitochondrial respiration, ROS generation and protein abundance as well as α-synuclein pathology in malathies. These results may explain why, in the hands of many research groups, this model does not elicit pronounced Parkinson's disease-like symptoms in the absence of mitochondrial dysfunction. This despite the presence of significant α-synuclein pathology in brain regions involved in non-motor (amygdala) and motor (striatum) disease symptoms. Our findings call for rigorous investigation of the short- and long-term effects of α-synuclein pathology on mitochondrial function/dysfunction in this model, particularly in brain regions strongly affected by neurodegeneration such as the substantia nigra pars compacta.Recurrent implantation failure (RIF) refers to repeated failure to become pregnant after transferring embryos with normal morphology. However, the pathogenesis of RIF remains unrevealed, especially for those without any pathological features. In this study, we characterized the vaginal microbiota and metabol
