THE RELATIONSHIP BETWEEN CHRONIC INFLAMMATION AND THE DEVELOPMENT OF NEURODEGENERATIVE DISEASES

Abstract

Neurodegenerative diseases represent a growing public health challenge due to their devastating impact on the quality of life and neurological functionality of affected individuals. Chronic inflammation has emerged as a potentially contributing factor to the pathogenesis of these debilitating diseases, offering a crucial field of study for understanding the mechanisms underlying their development. In this context, this study comprehensively investigated the relationship between chronic inflammation and neurodegenerative diseases, exploring the effects of persistent inflammation on the neuropathological profile, gene expression, oxidative homeostasis, and blood-brain barrier integrity. It was found that chronic inflammation is associated with significant changes in the neuropathological profile. The increased deposition of aggregated proteins, such as beta-amyloid and alpha-synuclein, suggests a direct relationship between the inflammatory response and the formation of pathological aggregates, characteristic of neurodegenerative diseases. Furthermore, neuronal loss and glial cell activation highlight the impact of chronic inflammation on neural architecture and tissue homeostasis.At the molecular level, a coordinated inflammatory response was observed, evidenced by increased expression of pro-inflammatory cytokines and of vascular adhesion. These modifications indicate a dynamic interaction between the immune and nervous systems, potentially amplifying the inflammatory response in the brain environment. In addition, analysis of antioxidant enzyme activity and oxidative stress revealed a complex relationship between inflammation and redox imbalance, contributing to neuronal deterioration and the progression of neurodegenerative diseases. by chronic inflammation. This dysregulation results in the entry of pro-inflammatory cytokines into the central nervous system, promoting bidirectional communication between the peripheral immune system and the brain environment. This interaction may play a crucial role in the amplification of the inflammatory response and the spread of neuroinflammation. In conclusion, the results of this study provide a deeper understanding of the relationship between chronic inflammation and the development of neurodegenerative diseases. The interconnection between inflammation, neuropathological profile, gene expression, oxidative stress and blood-brain barrier outlines a complex scenario of interactions that contribute to the pathogenesis of these debilitating diseases. These findings shed light on possible therapeutic targets to mitigate the deleterious effects of chronic inflammation in neurodegenerative diseases, promoting advances in the search for effective therapeutic strategies.
