  • Neurological pathogenesis of SARS-CoV-2 (COVID-19): from virological features to clinical symptoms

    Yoshitaka Kase, Hideyuki Okano

    Inflammation and Regeneration (Inflammation and Regeneration)  41 ( 15 ) 15 2021.05

     View Summary

    Since the worldwide outbreak of coronavirus disease 2019 (COVID-19) in 2020, various research reports and case reports have been published. It has been found that COVID-19 causes not only respiratory disorders but also thrombosis and gastrointestinal disorders, central nervous system (CNS) disorders, and peripheral neuropathy. Compared to other disorders, there are low number of research reports and low number of summaries on COVID-19-related neural disorders. Therefore, focusing on neural disorders, we outline both basic research and clinical manifestations of COVID-19-related neural disorders.

  • Current understanding of adult neurogenesis in the mammalian brain: how does adult neurogenesis decrease with age?

    Kase Y, Shimazaki T, Okano H

    Inflammation and regeneration (Inflammation and Regeneration)  40 ( 1 ) 10 2020

    Accepted,  ISSN  1880-9693

     View Summary

    © 2020 The Author(s). Adult neurogenesis occurs throughout life in restricted brain regions in mammals. However, the number of neural stem cells (NSCs) that generate new neurons steadily decreases with age, resulting in a decrease in neurogenesis. Transplantation of mesenchymal cells or cultured NSCs has been studied as a promising treatment in models of several brain injuries including cerebral infarction and cerebral contusion. Considering the problems of host-versus-graft reactions and the tumorigenicity of transplanted cells, the mobilization of endogenous adult NSCs should be more feasible for the treatment of these brain injuries. However, the number of adult NSCs in the adult brain is limited, and their mitotic potential is low. Here, we outline what we know to date about why the number of NSCs and adult neurogenesis decrease with age. We also discuss issues applicable to regenerative medicine.

  • Involvement of p38 in Age-Related Decline in Adult Neurogenesis via Modulation of Wnt Signaling

    Kase Y, Otsu K, Shimazaki T, Okano H

    Stem Cell Reports (Stem Cell Reports)  12 ( 6 ) 1313 - 1328 2019.05

    Research paper (scientific journal), Accepted,  ISSN  22136711

     View Summary

    © 2019 The Author(s) Neurogenesis in specific brain regions in adult mammals decreases with age. Progressive reduction in the proliferation of neural stem and progenitor cells (NS/PCs) is a primary cause of this age-associated decline. However, the mechanism responsible for this reduction is poorly understood. We identify p38 MAPK as a key factor in the proliferation of neural progenitor cells (NPCs) in adult neurogenic niches. p38 expression in adult NS/PCs is downregulated during aging. Deletion of p38α in NS/PCs specifically reduces the proliferation of NPCs but not stem cells. Conversely, forced expression of p38α in NS/PCs in the aged mouse subventricular zone (SVZ) restores NPC proliferation and neurogenesis, and prevents age-dependent SVZ atrophy. We also found that p38 is necessary for suppressing the expression of Wnt antagonists DKK1 and SFRP3, which inhibit the proliferation of NPCs. Age-related reduction in p38 thus leads to decreased adult neurogenesis via downregulation of Wnt signaling. Kase et al. show that p38 expression in neural stem and progenitor cells (NS/PCs) in the adult brain decreases with aging. This reduction specifically causes proliferation defect in neural progenitor cells (NPCs), leading to the age-dependent decline of adult neurogenesis. Conversely, overexpression of p38α in NS/PCs in the aged brain restores NPC proliferation without exhaustion of neural stem cells.

    近年報告されている脳内栄養因子等を用いた脳梗塞又はアルツハイマー病モデルマウス治療に関する研究においては、一時的な神経新生は認められるが、それらを用いることにより存神経幹細胞の枯渇を招く恐れがあり、治療後長期にわたってどのような弊害が出てくるのかわかっていない。本研究では、脳梗塞モデルマウス、認知症モデルマウスにおける障害海馬において残存神経幹細胞の枯渇を招かずに中長期的に神経回復を試みている。
