Exogenous Hsp70 delays senescence and improves cognitive function in aging mice
Open accessAbstract
Significance: The compromised ability of neurons to express Heat Shock Protein 70 (Hsp70) correlates with aging-related neurodegeneration. In this study, middle-aged and old mice were treated chronically until death with human Hsp70 delivered intranasally and were investigated after 5 or 9 mo of Hsp70 treatment for their cognitive ability and synaptic density. Hsp70 treatment extended mean and maximum lifespan, improved learning and memory in old animals, increased curiosity, decreased anxiety, and helped maintain synaptic structures that degrade with age. These results provide evidence that intranasal administration of Hsp70 could have significant therapeutic potential in preserving brain tissue and memory for middle-age and old individuals and could be applied either as unique self-contained treatment or in combination with other pharmacological therapies.

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.
