| Research Abstract |
So far, we suggested that, in the' refractory period' of the Xenopus tadpoles, immature immune cells attack blastema cells of the amputated tails as' non-self', resulting in failure in tail regeneration, whereas, in the' regeneration period', regulatory T cells differentiate to reactivate tail regenerative ability. However, what kinds of immune cells target the blastema cells remains unclear. In the present study, we identified a novel gene that is supposed to be expressed in immune cells that invade amputated tail stumps to repress tail regenerative ability. This gene played an essential role in tadpole survival during the developmental stages. This gene will be available as a maker for auto-reactive immune cells that attack tail blastema cells.
