Abstract

Abstract: Alzheimer's disease (AD) is a typical progressive, chronic neurodegenerative disorder with worldwide prevalence. Its clinical manifestation involves the presence of extracellular plaques and intracellular neurofibrillary tangles (NFTs). NFTs occur in brain tissues as a result of both Aβ agglomeration and Tau phosphorylation. Although there is no known cure for AD, research into possible cures and treatment options continues using cell‐cultures and model animals/organisms. The nuclear factor‐kappa β (NF‐κβ) plays an active role in the progression of AD. Impairment to this signaling module triggers undesirable phenotypic changes such as neuroinflammation, activation of microglia, oxidative stress related complications, and apoptotic cell death. These imbalances further lead to homeostatic abnormalities in the brain or in initial stages of AD essentially pushing normal neurons toward the degeneration process. Interestingly, the role of NF‐κβ signaling associated receptor‐interacting protein kinase is currently observed in apoptotic and necrotic cell death, and has been reported in brains. Conversely, the NF‐κβ signaling pathway has also been reported to be involved in normal brain functioning. This pathway plays a crucial role in maintaining synaptic plasticity and balancing between learning and memory. Since any impairment in the pathways associated with NF‐κβ signaling causes altered neuronal dynamics, neurotherapeutics using compounds including, antioxidants, bioflavonoids, and non‐steroidal anti‐inflammatory drugs against such abnormalities offer possibilities to rectify aberrant excitatory neuronal activity in AD. In this review, we have provided an extensive overview of the crucial role of NF‐κβ signaling in normal brain homeostasis. We have also thoroughly outlined several established pathomechanisms associated with NF‐κβ pathways in AD, along with their respective therapeutic approaches. Abstract : This review highlights the crucial interlink between impaired NF‐κβ signaling module and pathological occurrence of Alzheimer's disease, and how this cascade is being engaged in neuroprotection through having pharmacological approaches of different compounds including non‐steroidal anti‐inflammatory drugs (NSAIDs), bioflavonoids, and biomolecules to compensate such ailment is of significant interest. We think these findings provide a novel perspective for the treatment of NF‐κβ related brain insults.
