‘Hot spots’ of creatine kinase localization in brain: cerebellum, hippocampus and choroid plexus

Abstract

Creatine kinase (CK) isoenzymes, with emphasis on the mitochondrial CK isoenzymes, were characterized and localized in chicken cerebellum. Chicken cerebellum extracts analyzed by two-dimensional gels, using antipeptide antibodies specific for sarcomeric muscle-type mitochondrial CK (Mib-CK) and revealed the presence of a Mib-CK variant in avian cerebellum. This CK isoform was localized by immunofluorescence staining exclusively in the Purkinje neurons. The co-expression of this Mib-CK together with cytosolic muscle-type MM-CK, as observed in the same Purkinje neurons, may reflect the specific energy requirements associated with highly fluctuating Ca2+ levels (Ca2+ spiking) in these specialized neurons. Ubiquitous brain-type mitochondrial Mia-CK was found together with cytosolic BB-CK mainly in the glomeruli structures of the cerebellar granular layer. BB-CK, but much less so Mia-CK however, was also very prominent in Bergmann glial cells of the two mitochondrial Mi-CK isoenzymes in the chicken cerebellum is demonstrated. Other hot spots of CK localization were the granule and pyramidal cells of the hippocampus in rat. There, a developmental stage-dependent immunofluorescence staining, especially with antibodies against Mia-CK was noted. Epithelial cells of the choroid plexus were also highly enriched in CK. The possible implications of a CK/PCr circuit at these various cellular locations of the brain are discussed with respect to normal brain physiology and pathology.

  • Creatine-deficient syndromes that deplete brain creatine stores are characterized by mental and developmental disorders such as learning delays and seizures, and these symptoms can be partially reversed by creatine supplementation.

    “As an example of the importance of creatine in humans, creatine-deficient syndromes that deplete brain creatine stores are characterized by mental and developmental disorders such as learning delays and seizures17,18; importantly, these symptoms can be partially reversed by creatine supplementation.19–21”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
