Extrinsic signals from the meninges play a critical role in shaping cerebellar maturation.
Meningeal immune cells form a dynamic interface that potentially shapes neuronal positioning and cerebellar circuit formation.
The meninges release cytokines, chemokines, and growth factors including CXCL12, IGF-1, IL-33, FGF2, TGF-beta, and retinoic acid that influence granule cell precursor proliferation, Purkinje cell maturation, radial glia organization, and synaptic refinement.
Disruption of meningeal-derived developmental signals through genetic mutations, immune dysregulation, or environmental insults leads to impaired foliation, ectopic neuronal migration, and aberrant cerebellar architecture.
