滤泡树突状细胞(FDC)的分化对于淋巴滤泡具有显著的显微解剖可塑性至关重要。在这里,我们表明,功能树突状细胞起源于无处不在的血管周围前体细胞(PreFDC),表达血小板衍生生长因子受体β(PDGFRβ)。PDGFRβ-Cre驱动的报告基因重组导致FDC标记,而PDGFRβ+来源细胞的条件性消融使FDC消失,提示FDC来源于PDGFRβ+细胞。淋巴毒素-α高表达的Prion蛋白(PrP)+肾脏移植到PrP小鼠体内后发生PrP+FDC,证实前FDC存在于淋巴器官外。脂肪组织来源的PDGFRβ+基质血管细胞对FDC成熟因子有反应,将其移植到淋巴毒素β受体(LTβR)肾胶囊中,分化为Mfge8+CD2 1/35+FcγRIIβ+PrP+FDC,具有捕获免疫复合物和募集B细胞的能力。淋巴细胞缺陷小鼠的脾含有血管周围的PDGFRβ+FDC前体细胞,其扩张需要淋巴组织诱导细胞和淋巴毒素。前FDC的普遍存在及其在血管中的战略位置可能解释了淋巴细胞性炎症部位有组织的淋巴组织的从头生成。
The differentiation of follicular dendritic cells (FDC) is essential to the remarkable microanatomic plasticity of lymphoid follicles. Here we show that FDC arise from ubiquitous perivascular precursors (preFDC) expressing platelet-derived growth factor receptor β (PDGFRβ). PDGFRβ-Cre-driven reporter gene recombination resulted in FDC labeling, whereas conditional ablation of PDGFRβ+-derived cells abolished FDC, indicating that FDC originate from PDGFRβ+ cells. Lymphotoxin-α-overexpressing prion protein (PrP)+ kidneys developed PrP+ FDC after transplantation into PrP mice, confirming that preFDC exist outside lymphoid organs. Adipose tissue-derived PDGFRβ+ stromal-vascular cells responded to FDC maturation factors and, when transplanted into lymphotoxin β receptor (LTβR) kidney capsules, differentiated into Mfge8+CD21/35+ FcγRIIβ+PrP+ FDC capable of trapping immune complexes and recruiting B cells. Spleens of lymphocyte-deficient mice contained perivascular PDGFRβ+ FDC precursors whose expansion required both lymphoid tissue inducer (LTi) cells and lymphotoxin. The ubiquity of preFDC and their strategic location at blood vessels may explain the de novo generation of organized lymphoid tissue at sites of lymphocytic inflammation.
