Summary: In this study, a non-invasive intranasal delivery system using novel chitosan decorated nanoparticles was developed and evaluated for the treatment of cognitive dysfunction in Alzheimer's disease. The results showed that the chitosan decorated nanoparticles improved cognitive function in an animal model of Alzheimer's disease, indicating their potential as a safe and effective therapeutic approach.

Summary: Alzheimer's disease (AD) and major depressive disorder (MDD) are two common diseases that affect many people. Decreased hippocampal volumes and impaired hippocampal neurogenesis are observed in both AD and MDD. MDD is suggested to be a risk factor for developing AD, and the co-occurrence of depression and AD indicates a worse prognosis. Exercise has shown promising results in increasing hippocampal neurogenesis and improving mood in MDD, as well as enhancing quality of life and cognitive function in AD. However, more randomized control trials are needed to evaluate exercise as an intervention in treating MDD and preventing AD.

Summary: The study found that a high-tryptophan diet can significantly alleviate cognitive impairment and reduce amyloid-beta deposits by regulating gut microbiota. These findings suggest that the anti-inflammatory effects of a high-tryptophan diet are mediated by upregulating AhR and suppressing the NF-kappa B pathway, possibly through the regulation of gut microbiota, indicating that a tryptophan-rich diet may be a potential strategy for Alzheimer's disease intervention.

Summary: This study explored the regulatory effects of MAGI2-AS3 and miR-374b-5p on A beta-induced neurotoxicity and neuroinflammation in Alzheimer's disease. The findings suggest that the MAGI2-AS3/miR-374b-5p axis may serve as potential biomarkers and therapeutic targets for AD, as it can attenuate neuronal injury and inflammation. The expression levels of MAGI2-AS3 and miR-374b-5p were negatively correlated in AD patients and correlated with disease severity, highlighting their potential importance in AD pathogenesis.

Summary: Alzheimer's disease is characterized by protein deposition and neuronal loss. Mitophagy, responsible for maintaining mitochondrial quality, decreases with age and contributes to neurodegeneration in AD. Restoring mitophagy function could be a potential therapeutic strategy for AD.

Summary: This study investigated the effects of treadmill exercise on neuroinflammation in APP/PS1 transgenic AD mice and found that exercise can enrich gut microbial diversity and alleviate neuroinflammation in the brain. Exercise led to reductions in pathogenic bacteria, increases in probiotic bacteria, increased levels of intestine-brain barrier proteins, and attenuated LPS displacement.

Summary: The study found that long-term multicomponent exercise training can prevent amyloid-beta neurotoxicity in the hippocampus, reducing oxidative stress, restoring antioxidant capacity, increasing glutathione levels, and ultimately preventing recognition memory deficits.

Summary: The study found biphasic changes of miR-331-3p and miR-9-5p in AD progression, inhibiting these two microRNAs can promote autophagic clearance of A beta and prevent AD development. This was demonstrated in experiments and offers a potential new therapeutic strategy for AD patients.

Summary: Alzheimer's disease is a common age-related neurodegenerative disease with characteristic pathological features, and the activation of NLRP3 inflammasome plays a crucial role in its pathogenesis. Chronic neuroinflammation is an important factor in the development of AD, and targeting NLRP3 inflammasome pharmacologically can provide new therapeutic strategies.

Summary: Alzheimer's disease (AD) is a progressive neurodegenerative disease characterized by abnormal deposition of amyloid-beta, neurofibrillary tangles, synaptic dysfunction, and neuroinflammation. Currently, therapeutic interventions for AD are limited to symptomatic relief. However, our study shows that Methylprednisolone (MP), a synthetic glucocorticoid with anti-inflammatory properties, has a neuroprotective effect in an AD mouse model. MP treatment improves cognitive function, reduces microglial activation, and positively influences synaptic function and inflammatory processes. This suggests that MP could be a promising alternative for AD treatment, alone or in combination with other drugs.
