Immunological Senescence in Mice and Its Reversal by Coenzyme Q10
Abstract
A pronounced suppression of the humoral, hemolytic, primary immune response in old (22 months) mice was demonstrated as compared with this response in young (10 weeks) mice. The suppression is associated with a lower thymus weight:body weight ratio. In contrast, the ratios spleen weight:body weight and liver weight:body weight in 10 weeks and 22 months old mice remain almost constant. A single administration of coenzyme Q10--a non-toxic, non-specific stimulant of the host defense system--partly compensates the age-determined suppression of the humoral, immune response. This suppression probably results from an age-dependent imbalance of T cells: B cells ratio and a decline of their immunological responsiveness which is compensated by the administration of coenzyme Q10.

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.
