Overview

Hiroyuki Arai is affiliated with the University of Tokyo in Japan and conducts research primarily within the fields of Medicine and Biochemistry, Genetics and Molecular Biology. Their work intersects multiple subfields including Molecular Biology, Immunology, Neurology, Infectious Diseases, and Physiology.

The scientist's research covers a range of topics, particularly focusing on immune response mechanisms and neurological conditions. Main research topics include:

  • Interferon and immune responses
  • Viral infections and vectors
  • Alzheimer's disease research and treatments
  • Neuroinflammation and neurodegeneration mechanisms
  • Dementia and cognitive impairment research
  • Inflammasome and immune disorders
  • Antioxidant activity and oxidative stress

They have published in several frequent venues, including:

  • bioRxiv (Cold Spring Harbor Laboratory)
  • Nature Communications
  • Scientific Reports
  • Metabolites
  • Proceedings for Annual Meeting of The Japanese Pharmacological Society

Co-authors frequently collaborating with Arai comprise:

  • Nozomu Kono
  • Katsutoshi Furukawa
  • Kojiro Mukai
  • Tomohiko Taguchi
  • Kazuhiko Yanai

Notable recent publications include:

  • STING signalling is terminated through ESCRT-dependent microautophagy of vesicles originating from recycling endosomes, 2023, Nature Cell Biology
  • Homeostatic regulation of STING by retrograde membrane traffic to the ER, 2021, Nature Communications
  • LPIAT1/MBOAT7 depletion increases triglyceride synthesis fueled by high phosphatidylinositol turnover, 2020, Gut
  • YAP-dependent necrosis occurs in early stages of Alzheimer's disease and regulates mouse model pathology, 2020, Nature Communications
  • 18F-SMBT-1: A Selective and Reversible PET Tracer for Monoamine Oxidase-B Imaging, 2020, Journal of Nuclear Medicine

These publications reflect Arai's involvement in both fundamental molecular biology and clinical neuroscience research, with strong ties to neurodegenerative disease mechanisms and immune system regulation.
