Summary: The NF-kappa B pathway plays a crucial role in various diseases, including Alzheimer's disease. It has the potential to mitigate neuroinflammation, modulate amyloid beta production, and promote neuronal survival in the progression of Alzheimer's disease. However, there are limitations and challenges associated with this approach, as balancing inflammation inhibition and preserving physiological immune responses is critical.

Summary: This study compared the beneficial effects of different doses of OC-low EVOO and OC on A beta and related pathology as well as neuroinflammation in 5xFAD mice. The results showed that 0.5 mg/kg EVOO-phenols and OC reduced brain A beta levels and neuroinflammation by suppressing the NF-kappa B pathway and inhibiting the activation of NLRP3 inflammasomes. However, only OC suppressed the RAGE/HMGB1 pathway. In conclusion, dietary supplementation with EVOO or OC can prevent, halt progression, and treat AD.

Summary: In this study, the potential of a compound called W112 for the treatment of Alzheimer's disease (AD) was investigated. The results showed that W112 has neuroprotective effects against AD-like pathology, improving learning and memory abilities in AD-induced rats and reversing tau hyperphosphorylation. It also reduced the production of proinflammatory cytokines in vitro and in vivo.

Summary: This study evaluated the neuroprotective effects of Lingguizhugan decoction (LGZGD) on Aβ25-35-induced PC12 cells and elucidated its molecular mechanism. The results showed that LGZGD increased cell viability, reduced inflammatory factors, inhibited cell apoptosis, and modulated the NF-κB/MAPK signaling pathways. Therefore, LGZGD may be a valuable drug candidate for attenuating Aβ25-35-induced neurotoxicity.

Summary: Cellular senescence is a fundamental activity driving the aging process and is closely associated with age-related diseases, including Alzheimer's disease (AD). In this study, the elevated levels of lactic acid in senescent microglia and hippocampus tissues of naturally aged mice and AD mice models were quantified. The study also identified the role of H3K18la/NF?B axis in modulating the production of IL-6 and IL-8, which are components of the senescence-associated secretory phenotype (SASP).

Summary: Autophagy is essential for cellular homeostasis, and dysregulation in this pathway is implicated in neurodegenerative disorders. TFEB, a key regulator of autophagy and lysosomal biogenesis, is considered a potential therapeutic target for treating these disorders. Studies have shown that targeting TFEB may help alleviate neurotoxicity and rescue neurodegeneration in animal models, providing insights for potential therapeutic strategies in neurodegenerative disorders.

Summary: Alzheimer's disease is the most common form of dementia among the elderly, characterized by Aβ plaque deposition, disrupted blood-brain barrier, and neuroinflammation. Olive leaf extract has been found to improve memory function by inhibiting inflammation, enhancing Aβ clearance, and improving blood-brain barrier integrity. Therefore, olive leaf extract may serve as a dietary supplement to prevent and slow down the progression of Alzheimer's disease.

Summary: This study found increased concentration of molecules related to inflammatory response in AD patients and observed that ROF treatment could decrease expression of apoptosis-related molecules by inhibiting the PI3K/AKT/mTOR signaling pathway, as well as increase key enzyme expression in the tricarboxylic acid (TCA) cycle in SH-SY5Y cells. Inhibition of NF-kappa B could enhance these effects, while overexpression of NF-kappa B could diminish them.

Summary: In this study, RPS23RG1 was found to play a role in tauopathies by regulating the degradation of p35 and suppressing Cdk5 activation to inhibit tau hyperphosphorylation. Reduced levels of RPS23RG1 trigger aberrant Cdk5-p35 activation, leading to tau hyperphosphorylation and impaired axon outgrowth. These findings suggest that RPS23RG1 may serve as a potential therapeutic target in tauopathy disorders.

Summary: Recent research has found that shedding of CSF1R and TREM2 may play a role in neurodegenerative diseases, particularly the CSF1R I794T variant. Inhibition of shedding was shown to decrease cleaved fragments associated with the I794T variant, suggesting that the cleaved ectodomain fragment may serve as a diagnostic biomarker for ALSP.

Summary: The study compared sexual dimorphism in gene expression across primary neurons, astrocytes, and microglia derived from neonatal mouse brains, revealing different levels of sexually dimorphic genes in these primary cells, with enrichment in immune-related pathways. The sexually dimorphic genes were predominantly located on the Y chromosome, and overexpression of Eif2s3y specifically affected synaptic transmission in male neurons and caused autism-like behaviors in male mice, providing new insights into sex differences in neurological disorders.

Summary: A novel pathogenic missense mutation in the CNTNAP2 gene was found in an infant with spontaneous recurrent seizures and intellectual disability. This mutation led to changes in neuron morphology and function, causing an imbalance in excitatory and inhibitory post-synaptic currents in the neural network, potentially contributing to the occurrence of SRSs.

Summary: The study identified KP372-1 as a potential anticancer agent targeting NQO1 to induce ROS generation and DNA damage in cancer cells. Combination therapy of KP372-1 and PARPi rucaparib enhanced lethality in NQO1 over-expressing cancers by inhibiting DNA repair and overcoming PARPi resistance. PARP inhibition reversed KP372-1-induced PARP1 hyperactivation, promoted Ca2+-dependent autophagy and apoptosis, and synergistically suppressed tumor growth in mouse models.

Summary: This study examined the age-related changes in brain function and baseline brain structure that support motor skill acquisition. The findings showed that older adults experienced decreases in functional connectivity during motor skill acquisition, while younger adults experienced increases. Additionally, regardless of age group, lower baseline microstructure in a frontoparietal tract was associated with slower motor skill acquisition.

Summary: Physical exercise has a positive impact on hippocampal memory decline with aging. Recent studies have shown that even light exercise can improve memory and this improvement is mediated by the ascending arousal system. This study aimed to investigate the effects of light-intensity exercise on hippocampal memory function in healthy older adults and found that pupil dilation during exercise played a role in the memory improvement.

Summary: This study investigated the effects of age on the robustness and resilience of auditory system using the desert locust. The researchers found that gene expression changes were mainly influenced by age rather than noise exposure. Both young and aged locusts were able to recover their auditory nerve function within 48 hours of noise exposure, but the recovery of transduction current magnitude was impaired in aged locusts. Key genes responsible for robustness to noise exposure in young locusts and potential candidates for compensatory mechanisms in auditory neurons of aged locusts were identified.
