- From peripheral to central (Neuro)degeneration: Is heart-kidney a new axial paradigm for Parkinson’s disease?Publication . Teixeira, Catarina; Caridade-Silva, Rita; Martins-Macedo, Joana; Araújo, Bruna; Gomes, Eduardo; Vilela, Cristiana; Soares-Guedes, Carla; Pires, Inês Falcão; Alencastre, Inês; G. Teixeira, Fábio; Gomes, EduardoParkinson’s Disease (PD) is primarily characterized by the accumulation of alpha-synuclein (αSyn) and the loss of dopaminergic neurons (DAn). The most evident repercussions of the disease include sympathetic and parasympathetic dysfunction, decreased dopamine (DA) levels, and impaired voluntary movements. Given the multifactorial nature of PD, it is now recognized that several systemic diseases may predispose individuals to the onset and progression of PD as well as influence its therapeutic outcomes. Recent studies have highlighted that patients with cardiovascular disease (CVD) and chronic kidney disease (CKD) face an increased risk of developing PD, independent of the shared risk factors. Indeed, substantial evidence supports the connections between the brain, heart, and kidneys. Elements such as the dopaminergic system, blood pressure regulation, inflammation, autophagy, oxidative stress, and calcium (Ca2+) signaling are recognized as crucial for the functioning of each organ individually. However, these factors may also significantly impact the overall health of the triad. Understanding the interconnection between the brain, heart, and kidneys would be groundbreaking in enhancing our knowledge about their interactions, enabling prompt interventions in the early stages of the disease. With this perspective, this review analyzes the current understanding of the brain-heart-kidney axis as a potential new paradigm for diagnosing and managing PD.
- Neuroinflammation and Parkinson’s disease—from neurodegeneration to therapeutic opportunitiesPublication . Araújo, Bruna; Caridade-Silva, Rita; Soares-Guedes, Carla; Martins-Macedo, Joana; Gomes, Eduardo D.; Monteiro, Susana; Teixeira, Fábio G.Parkinson’s disease (PD) is the second most prevalent neurodegenerative disorder world wide. Clinically, it is characterized by a progressive degeneration of dopaminergic neurons (DAn), resulting in severe motor complications. Preclinical and clinical studies have indicated that neuroin flammation can play a role in PD pathophysiology, being associated with its onset and progression. Nevertheless, several key points concerning the neuroinflammatory process in PD remain to be answered. Bearing this in mind, in the present review, we cover the impact of neuroinflammation on PD by exploring the role of inflammatory cells (i.e., microglia and astrocytes) and the interconnections between the brain and the peripheral system. Furthermore, we discuss both the innate and adaptive immune responses regarding PD pathology and explore the gut–brain axis communication and its influence on the progression of the disease.
