Calcium channels and iron metabolism: A redox catastrophe in Parkinson’s disease and an innovative path to novel therapies?

Iron, Parkinson's Disease, Pre-PD /

Autonomously spiking dopaminergic neurons of the substantia nigra pars compacta (SNpc) are exquisitely specialized and suffer toxic iron-loading in Parkinson’s disease (PD). However, the molecular mechanism involved remains unclear and critical to decipher for designing new PD therapeutics. The long-lasting (L-type) CaV1.3 voltage-gated calcium channel is expressed at high levels amongst nigral neurons of the […]

Natural antioxidants in the management of Parkinson’s disease: review of evidence from cell line and animal models

Anti-oxidants, Diet and Exercise, Parkinson's Disease, Therapies /

Therefore, the use of natural antioxidants in PD may provide an alternative therapy that prevents oxidative stress and reduces disease progression. In this review, the effects of hydroxytyrosol, Ginkgo biloba, Withania somnifera, curcumin, green tea, and Hypericum perforatum in PD animal and cell line models are compared and discussed. The reviewed antioxidants show evidence of protecting neural cells from

Diet and the Microbiota–Gut–Brain Axis: Sowing the Seeds of Good Mental Health

Biomarkers, Diet and Exercise, Gut Microbiota, Gut-Brain axis, Short Chain Fatty Acids /

Animal studies investigating the potential of nutritional interventions on the microbiota–gut–brain axis have led to advancements in our understanding of the role of diet in this bidirectional communication. In this review, we summarize the current state of the literature triangulating diet, microbiota, and host behavior/brain processes and discuss potential underlying mechanisms. Additionally, determinants of the

Fecal transplants as a microbiome-based therapeutic

Fecal Transplants (FMT), Therapies /

Impaired microbiome diversity and composition can develop into a potent etiological agent of disease and increase susceptibility to infection. Given this, interventions targeting the microbiome have developed rapidly, with healthy donor feces being a de facto source of beneficial communities employed to rebalance patients’ microbiomes. Recent evidence has demonstrated that bacterial and viral richness, short
