Article Abstract

Neurodegenerative diseases are incurable and debilitating conditions characterized by the deterioration of brain function. Most brain disease models rely on human post-mortem brain tissue, non-human primate tissue, or in vitro two-dimensional (2D) experiments. Resource limitations and the complexity of the human brain are some of the reasons that make suitable human neurodegenerative disease models inaccessible. However, recently developed three-dimensional (3D) brain organoids derived from pluripotent stem cells (PSCs), including embryonic stem cells and induced PSCs, may provide suitable models for the study of the pathological features of neurodegenerative diseases. In this review, we provide an overview of existing 3D brain organoid models and discuss recent advances in organoid technology that have increased our understanding of brain development. Moreover, we explain how 3D organoid models recapitulate aspects of specific neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and Huntington's disease, and explore the utility of these models, for therapeutic applications.

Microglia, the resident immune cells of the central nervous system (CNS), are involved in the pathogenesis of neurodegenerative diseases, such as Alzheimer's disease (AD), Dementia with Lewy Bodies (DLB), and Parkinson's disease (PD). 14-3-3 proteins act as molecular hubs to regulate protein-protein interactions, which are involved in numerous cellular functions, including cellular signaling, protein folding, and apoptosis. We previously revealed decreased 14-3-3 levels in the brains of human subjects with neurodegenerative diseases.

While agriculture is essential for food security, the intensive use of pesticides in modern farming practices raises concerns on their impact, in particular from a One Health perspective. In 2024, Brazil approved 663 new pesticides, a 19% increase in comparison with 2023. The occupational exposure of rural workers is known to be associated with a range of health outcomes, including cancer.

Background: Y69H (p.Y89H) variant hereditary transthyretin (ATTRv) amyloidosis causes meningeal amyloidosis, with mutant TTR deposits localized to the leptomeninges and vitreous body.

Methods: The effect of tafamidis meglumine on neurological disorders, such as the frequency of transient focal neurological episodes (TFNEs), magnetic resonance imaging (MRI) findings, and TTR levels in cerebrospinal fluid, was investigated in two patients diagnosed with Y69H ATTRv mutation.

Brain aging is a major risk factor for cognitive decline and neurodegenerative diseases, driven by synaptic loss, reduced synaptic function, and inflammation. However, the molecular mechanisms underlying these dysfunctions remain unclear. Here, we conducted comparative transcriptomic analyses of brain regions (cortex and hippocampus) and kidney tissues, a peripheral organ with documented age-related dysfunction.

Neuroinflammation has emerged as a central and dynamic component of the pathophysiology underlying a wide range of neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, Huntington's disease, and multiple sclerosis. Far from being a secondary consequence of neuronal damage, inflammatory processes (mediated by microglia, astrocytes, peripheral immune cells, and associated molecular mediators) actively shape disease onset, progression, and symptomatology. This review synthesizes current knowledge on the cellular and molecular mechanisms that govern neuroinflammatory responses, emphasizing both shared and disease-specific pathways.
