The fibroblast growth factor (FGF) system is implicated in mood disorders like major depression. Reduced FGF signaling may increase vulnerability to these conditions by affecting brain development and plasticity.

Area of Science:

  • Neuroscience
  • Molecular Biology
  • Psychiatry

Background:

  • Emerging evidence links the fibroblast growth factor (FGF) system to mood disorders.
  • Several FGF family members show dysregulation in individuals with major depression.

Purpose of the Study:

  • To review the structure, function, and developmental roles of the FGF system.
  • To explore the FGF system's role as a mediator of neural plasticity.
  • To summarize current animal and human research on FGF and mood disorders.

Main Methods:

  • Review of existing literature on FGF system development, function, and plasticity.
  • Synthesis of findings from animal studies (stress, enrichment, pharmacology, hippocampus).
  • Analysis of human studies (volumetric measurements, antidepressant effects, post-mortem gene expression).

Main Results:

  • The FGF system plays a crucial role in neural development and adult brain function.
  • FGF signaling is altered in major depression, suggesting a link to the disorder.
  • Animal and human studies provide converging evidence for FGF's involvement.

Conclusions:

  • A diminished FGF system tone may impair brain development or remodeling.
  • This impairment could lead to an increased predisposition or vulnerability to mood disorders, including major depression.
