WebApr 19, 2024 · Given that Shh signaling occurs in the cerebellum during proliferation and that ablation or reduction of Shh signaling in Bergmann glia leads to proliferation deficits in the cerebellar GNPs in the EGL [14, 15], our results indicate that dysregulated Shh signaling in Bergmann glia through primary cilia reduction in Fmr1 KO mice may have … WebJan 23, 2024 · There are many diseases in which glial changes in the cerebellum are involved, such as ataxia, leukoencephalopathy, autism and attention-deficit/hyperactivity disorder (ADHD), multiple sclerosis, as well as hypothyroidism which characteristically involve severe glial dysfunction (Table 1 ).
WebThe developmental origin of the cerebellum is the hindbrain, together with the brainstem (midbrain, pons, and medulla oblongata). ... Bergmann glia are radial astrocytes specific for cerebellum located in the Purkinje layer with processes through the molecular layer all the way to the pial surface of the cerebellar cortex. WebOther functional and morphological distinct astrocytes are unipolar Bergmann glia with radial ascending processes and elongated radial glia-like tanycytes. In the cerebellum, Bergmann glia control the synapsis of Purkinje cells (De Zeeuw and Hoogland, 2015), while in the hypothalamus, tanycytes are specialized in the modulation of ...
