JAG2 signaling induces differentiation of CD14+ monocytes into Langerhans Cell Histiocytosis-like cells

This study aims to identify the cell of origin of Langerhans Cell Histiocytosis and the molecular mechanisms of its pathogenesis. Primary cells were isolated from peripheral blood (CD14 monocytes, CD1c DCs) and treated with JAG2, IgG or IL4 6 different conditions: CD14 and CD1c treated with IgG, JAG2 or IL4

本研究旨在明确朗格汉斯细胞组织细胞增生症（Langerhans Cell Histiocytosis）的起源细胞及其发病的分子机制。研究人员从外周血中分离原代细胞，涵盖CD14单核细胞（CD14 monocytes）及CD1c型树突状细胞（CD1c DCs），并将其置于6种不同培养条件下，分别以JAG2、免疫球蛋白G（IgG）及白细胞介素4（IL4）进行处理：具体为CD14单核细胞与CD1c型树突状细胞分别经IgG、JAG2或IL4处理。
