Suppression of the immune response potentiates tadpole tail regeneration during the refractory period

Abstract

Regenerative ability varies depending on animal species and developmental stage, but the factors that determine this variability remain unclear. Although Xenopus laevis tadpole tails possess high regenerative ability, this is transiently lost during the `refractory period'. Here, we show that tail amputation evokes different immune responses in wound tail stumps between the `refractory' and `regeneration' periods: there was delayed or prolonged expression of some immune-related genes in the refractory period,whereas there was no obvious or transient expression of other immune-related genes in the regeneration periods. In addition, immune suppression induced by either immunosuppressant treatment or immune cell depletion by knockdown of PU.1 significantly restored regenerative ability during the refractory period. These findings indicate that immune responses have a crucial role in determining regenerative ability in Xenopus tadpole tails.

  • The refractory period in tadpole development coincides with a spike in immune cell presence.

    “For example, the refractory period in tadpole development (when these organisms are unable to regenerate a tail) coincides with a spike in immune cell presence (133);”

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.
