  • To explore the potential of the turquoise killifish as a model organism for aging and neurodegeneration.

Main Methods:

  • Literature review focusing on mitochondrial dysfunction in neurodegeneration.
  • Analysis of small fish characteristics relevant to disease modeling (genetic homology, imaging, manipulation).
  • Examination of existing studies on mitochondria-related neuronal disorders in fish models.

Main Results:

  • Mitochondrial dysfunction is a key factor in neurodegenerative disease progression.
  • Small fish possess advantageous traits for in vivo research, including genetic and histological similarity to humans.
  • Previous studies demonstrate the efficacy of small fish in modeling neuronal disorders.

Conclusions:

  • Small fish models are crucial for advancing in vivo studies of mitochondrial function and neurodegenerative disease pathogenesis.
  • These models hold significant promise for the development of novel therapeutic strategies.
  • The turquoise killifish presents a unique and valuable model for aging and neurodegenerative disease research.
