FOXO转录因子在调控涉及分化、细胞周期停滞、细胞凋亡和DNA修复的基因转录方面具有高度保守的作用。此前已有研究表明,小鼠体内FOXO_3的缺失会导致骨髓增生性疾病。与此一致,我们发现一个独立的Foxo3缺失小鼠品系Foxo3 KCA在脾、骨髓和血液中显示出中性粒细胞的增加。这与包括粒细胞-巨噬细胞前体细胞(前GM)和粒细胞-巨噬细胞前体细胞(GMP)在内的髓系祖细胞的扩张不谋而合。令人惊讶的是,尽管有中性粒细胞增多,Foxo3 KCA小鼠的被动血清转移性关节炎的严重程度却显著减轻。这些缺陷似乎至少部分是髓系固有的,因为使用LysMCre从髓系细胞中特异性删除Foxo3也会导致中性粒细胞数量增加,并对K/BxN血清转移诱导的关节炎具有保护作用。
FOXO transcription factors have a highly conserved role in regulating transcription of genes involved in differentiation, cell cycle arrest, apoptosis and DNA repair. Loss of FOXO3 in mice has previously been shown to result in a myeloproliferative disease. In agreement with this, we found that an independent Foxo3 null mouse strain, Foxo3 Kca, exhibits an increase in neutrophils in the spleen, bone marrow and blood. This coincides with an expansion of myeloid progenitor cells including pre-granulocyte-macrophage progenitors (Pre-GMs) and granulocyte-macrophage progenitors (GMPs). Surprisingly, despite neutrophilia, the severity of passive serum transfer arthritis was markedly attenuated in Foxo3 Kca mice. These defects appear to be at least partially intrinsic to the myeloid lineage, as deleting Foxo3 specifically from myeloid cells using LysMCre also leads to an elevated number of neutrophils and protection from K/BxN-serum transfer-induced arthritis.
