Exercise induces BDNF and synapsin I to specific hippocampal subfields

Vaynman, Shoshanna, Ying, Zhe, Gómez‐Pinilla, Fernando·2004·Journal of Neuroscience Research

Abstract

To assess the relationship between brain-derived neurotrophic factor (BDNF) and synapsin I in the hippocampus during exercise, we employed a novel microsphere injection method to block the action of BDNF through its tyrosine kinase (Trk) receptor and subsequently measure the mRNA levels of synapsin I, using real-time TaqMan RT-PCR for RNA quantification. After establishing a causal link between BDNF and exercise-induced synapsin I mRNA levels, we studied the exercise-induced distribution of BDNF and synapsin I in the rodent hippocampus. Quantitative immunohistochemical analysis revealed increases of BDNF and synapsin I in CA3 stratum lucidum and dentate gyrus, and synapsin I alone in CA1 stratum radiatum and stratum laconosum moleculare. These results indicate that exercise induces plasticity of select hippocampal transsynaptic circuitry, possibly comprising a spatial restriction on synapsin I regulation by BDNF.

  • BDNF is mechanistically linked to exercise-induced improvement in cognitive functions, such as memory and learning.

    “Furthermore, BDNF has been shown to be mechanistically linked to exercise-induced improvement in cognitive functions, such as memory and learning (93, 94).”

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.
