| Description |
The caudal hematopoietic tissue in zebrafish, the equivalent to the fetal liver in mammals, is an intermediate hematopoietic niche for the maintenance and differentiation of hematopoietic stem and progenitor cells before homing to the thymus and kidney marrow. As one of the ultimate hematopoietic organs, the thymus sustains T lymphopoiesis, which is essential for adaptive immune system. However, the mechanism of prethymic T lymphoid progenitors migrating to the thymus remains elusive. In this study, we identify an Rho GTPase Rac2 as a modulator of T lymphoid progenitor homing to the thymus in zebrafish. rac2-Deficient embryos show the inability of T lymphoid progenitors homing to the thymus because of defective cell-autonomous motility. Mechanistically, we demonstrate that Rac2 regulates homing of T lymphoid progenitor through Pak1-mediated AKT pathway. Taken together, our work reveals an important function of Rac2 in directing T lymphoid progenitor migration to the thymus during zebrafish embryogenesis. |
