In addition to tau pathology, the involvement of microglial receptors in AD has been elucidated. Research indicated that TAM receptors Axl and Mer are crucial for microglial detection and phagocytosis of amyloid-beta plaques, with their genetic ablation resulting in impaired microglial function in AD mouse models (ref: Huang doi.org/10.1038/s41590-021-00913-5/). This suggests that microglial activity is essential for plaque clearance and may influence disease progression. Moreover, a brain proteome-wide association study identified 25 proteins linked to depression, with implications for understanding comorbidities in AD (ref: Wingo doi.org/10.1038/s41593-021-00832-6/). The integration of these findings highlights the multifaceted nature of AD pathology, where molecular mechanisms, genetic predispositions, and immune responses converge to influence disease outcomes.

Furthermore, the study of tau aggregates revealed their impact on nuclear speckle components, suggesting that tau pathology may disrupt normal cellular functions, including pre-mRNA splicing (ref: Lester doi.org/10.1016/j.neuron.2021.03.026/). This disruption could contribute to the neuroinflammatory environment observed in AD. The interplay between tau pathology and immune responses highlights the complexity of neuroinflammation in AD, where both the innate immune system and tau-related processes may exacerbate neuronal damage. Collectively, these findings emphasize the importance of targeting neuroinflammatory pathways as potential therapeutic strategies in AD.

Moreover, the exploration of long non-coding RNAs (lncRNAs) has revealed their potential impact on disease susceptibility. The GTEx project v8 data analysis mapped lncRNA expression across various tissues, providing a comprehensive view of their genetic regulation and associations with complex traits, including AD (ref: de Goede doi.org/10.1016/j.cell.2021.03.050/). This highlights the multifactorial nature of AD, where genetic predispositions, metabolic factors, and environmental influences converge to shape disease risk. The integration of these findings underscores the need for a holistic approach in understanding AD, considering both genetic and environmental contributions to its pathogenesis.

Furthermore, the exploration of neural stem cell fate control using biohybrid micromotors presents a novel approach to potentially replace degenerated neurons in AD (ref: Liu doi.org/10.1021/acs.nanolett.1c00290/). This innovative strategy may offer new avenues for therapeutic interventions aimed at restoring cognitive function. Collectively, these findings emphasize the need for continued research into the cognitive and behavioral aspects of AD, as well as the development of targeted therapies to mitigate cognitive decline and improve patient outcomes.

Moreover, the identification of blood metabolites linked to midlife cognition through Mendelian randomization has opened new avenues for understanding preclinical biomarkers in AD (ref: Lord doi.org/10.1073/pnas.2009808118/). This approach emphasizes the potential for early intervention strategies targeting metabolic pathways. The integration of these findings highlights the importance of a multifaceted approach to AD therapy, combining molecular insights with innovative interventions to address the complex nature of the disease.

Furthermore, the exploration of long non-coding RNAs (lncRNAs) has provided a broader understanding of the molecular landscape in AD. The GTEx project v8 data analysis revealed the expression and genetic regulation of lncRNAs across various tissues, suggesting their potential role in neurodegenerative processes (ref: de Goede doi.org/10.1016/j.cell.2021.03.050/). Collectively, these findings emphasize the need for continued research into the molecular mechanisms underlying protein aggregation and neurodegeneration, as well as the potential for targeting these pathways in therapeutic interventions.

Moreover, the exploration of neural stem cell fate control using biohybrid micromotors presents a promising avenue for therapeutic interventions in neurodegenerative diseases, including Alzheimer's (ref: Liu doi.org/10.1021/acs.nanolett.1c00290/). These innovative approaches may offer new strategies for addressing cognitive decline and enhancing patient outcomes. Collectively, these clinical and epidemiological findings emphasize the need for ongoing research to better understand the complexities of Alzheimer's disease and to develop targeted interventions that can effectively address its growing prevalence.
