    Alzheimer's disease (AD) is characterized by the extensive deposition of amyloid-β peptide (Aβ) in the brain. Brain Aβ level is regulated by a balance between Aβ production and clearance. The clearance rate of Aβ is decreased in the brains of sporadic AD patients, indicating that the dysregulation of Aβ clearance mechanisms affects the pathologic process of AD. Astrocytes are among the most abundant cells in the brain and are implicated in the clearance of brain Aβ via their regulation of the blood-brain barrier, glymphatic system, and proteolytic degradation. The cellular morphology and activity of astrocytes are modulated by several molecules, including ω3 polyunsaturated fatty acids, such as docosahexaenoic acid, which is one of the most abundant lipids in the brain, via the G protein-coupled receptor GPR120/FFAR4. In this study, we analyzed the role of GPR120 signaling in the Aβ-degrading activity of astrocytes. Treatment with the selective antagonist upregulated the matrix metalloproteinase (MMP) inhibitor-sensitive Aβ-degrading activity in primary astrocytes. Moreover, the inhibition of GPR120 signaling increased the levels of Mmp2 and Mmp14 mRNAs, and decreased the expression levels of tissue inhibitor of metalloproteinases 3 (Timp3) and Timp4, suggesting that GPR120 negatively regulates the astrocyte-derived MMP network. Finally, the intracerebral injection of GPR120-specific antagonist substantially decreased the levels of TBS-soluble Aβ in male AD model mice, and this effect was canceled by the coinjection of an MMP inhibitor. These data indicate that astrocytic GPR120 signaling negatively regulates the Aβ-degrading activity of MMPs.SIGNIFICANCE STATEMENT The level of amyloid β (Aβ) in the brain is a crucial determinant of the development of Alzheimer's disease. Here we found that astrocytes, which are the most abundant cell type in the CNS, harbor degrading activity against Aβ, which is regulated by GPR120 signaling. GPR120 is involved in the inflammatory response and obesity in peripheral organs. However, the pathophysiological role of GPR120 in Alzheimer's disease remains unknown. We found that selective inhibition of GPR120 signaling in astrocytes increased the Aβ-degrading activity of matrix metalloproteases. Our results suggest that GPR120 in astrocytes is a novel therapeutic target for the development of anti-Aβ therapeutics.

    Deposition of amyloid-β (Aβ) as senile plaques is one of the pathological hallmarks in the brains of Alzheimer's disease (AD) patients. In addition, glial activation has been found in AD brains, although the precise pathological role of astrocytes remains unclear. Here, we identified kallikrein-related peptidase 7 (KLK7) as an astrocyte-derived Aβ degrading enzyme. Expression of KLK7 mRNA was significantly decreased in the brains of AD patients. Ablation of Klk7 exacerbated the thioflavin S-positive Aβ pathology in AD model mice. The expression of Klk7 was upregulated by Aβ treatment in the primary astrocyte, suggesting that Klk7 is homeostatically modulated by Aβ-induced responses. Finally, we found that the Food and Drug Administration-approved anti-dementia drug memantine can increase the expression of Klk7 and Aβ degradation activity specifically in the astrocytes. These data suggest that KLK7 is an important enzyme in the degradation and clearance of deposited Aβ species by astrocytes involved in the pathogenesis of AD.
  • Dysregulated Metabolism of the Amyloid-β Protein and Therapeutic Approaches in Alzheimer Disease.

    Journal of cellular biochemistry, Dec. 2017
    Amyloid-β protein (Aβ) is the main component of senile plaques in the brains of Alzheimer disease (AD) patients. Aβ is proteolytically derived from amyloid-β precursor protein by β- and γ-secretases. Secreted Aβ is then eliminated from the central nervous system by multiple clearance mechanisms, including phagocytosis, immune responses, and proteolytic degradation. These dynamic metabolic processes, which are referred to as Aβ economy, regulate steady-state brain Aβ levels. Familial AD-linked genetic mutations augment the production and aggregation of Aβ. In contrast, rare genetic variants that reduce Aβ production were protective against AD. Moreover, decreased Aβ clearance has been demonstrated in sporadic AD patients, suggesting that dysregulation of Aβ economy contributes to the development of AD. Thus, several approaches to inhibit the production as well as to enhance the clearance of Aβ have been investigated as potential therapeutics against AD. In this manuscript, we introduce the molecules and cellular mechanisms involved in the regulation of Aβ economy and discuss the current understanding of these processes in the development of therapeutics against AD.

  • Memantine reduces the production of amyloid-β peptides through modulation of amyloid precursor protein trafficking.

    European journal of pharmacology, 05 Mar. 2017
    Memantine, an uncompetitive glutamatergic N-methyl-D-aspartate (NMDA) receptor antagonist, is widely used as medication for the treatment of Alzheimer's disease (AD). It has been reported that memantine reduces amyloid-β peptide (Aβ) levels in both neuronal cultures and in brains of animal models of AD. However, the underlying mechanism of these effects is unclear. Here we examined the effect of memantine on Aβ production. Memantine was administered to 9-month-old Tg2576 mice, a transgenic mouse model of AD, at 10 or 20mg/kg/day in drinking water for 1 month. Memantine significantly reduced the amounts of both CHAPS-soluble and CHAPS-insoluble Aβ in the brains of Tg2576 mice. Memantine at 10mg/kg/day for 1 month also reduced the levels of insoluble Aβ42 in the brains of aged F344 rats. Moreover, memantine reduced Aβ and sAPPβ levels in conditioned media from rat primary cortical cultures without affecting the enzymatic activities of α-secretase, β-secretase, or γ-secretase. Notably, in a cell-surface biotinylation assay, memantine increased the amount of amyloid precursor protein (APP) at the cell surface without changing the total amount of APP. Collectively, our results indicate that chronic treatment with memantine reduces the levels of Aβ both in AD models and in aged animals, and that memantine affects the endocytosis pathway of APP, which is required for β-secretase-mediated cleavage. This leads to a reduction in Aβ production. These results suggest that memantine reduces Aβ production and plaque deposition through the regulation of intracellular trafficking of APP.

    Takuya Tatebe, Toukatsu Pharmaceutical Study Group, 10 Jul. 2021, Japan
    The novel coronavirus disease (COVID-19), which emerged at the end of 2019, triggered a global pandemic and continues to spread worldwide. To overcome this crisis, the development of therapeutics and vaccines targeting the causative virus, SARS-CoV-2, is essential. In this presentation, I will focus on the currently approved treatments and vaccines, and share ongoing research efforts in Japan as well as around the world.

    Since the first cases of COVID-19 were identified in China in December 2019, the virus spread globally within a few months. During the peak of the pandemic, many people adopted mask-wearing, hand hygiene, and vaccination as routine measures, and the pandemic has since subsided. However, COVID-19 continues to be reported, and vigilance remains necessary. In this presentation, we will discuss the current status of viral infection, treatments, new types of vaccines, and infection control measures.

    We are developing a universal cancer therapeutic vaccine using killer T cells sensitized by the BCG vaccine. Since the majority of the population in Japan has received BCG vaccination, it is assumed that most individuals possess cellular immunity against BCG antigens. In fact, BCG antigen-reactive Th1 cells and killer T cells have been reported in BCG-vaccinated Japanese individuals. In this study, we aim to establish a method in which cancer cells are infected with a recombinant virus to specifically express BCG antigens, thereby enabling pre-existing BCG antigen-reactive killer T cells in the body to target and attack the cancer cells.
