  1. Dendritic cells are characterized by their ability to efficiently present antigen, and are uniquely equipped to stimulate naive t cell responses. immature dendritic cells acquire antigens from throughout the peripheral body, then migrate to t - lymphocyte - dependent areas of lymph nodes. thus, dendritic cells act as bridges, operating at the interface of innate and acquired immunity

    作為機體免疫系統中功能最強的專職性抗原提呈細胞（ antigen - presentingcells ， apc ） ，樹突狀細胞（ dendriticcells ， dc ）能高效地攝取、加工處理和提呈抗原，具有較強的遷移能力，並能顯著地激活初始型t細胞以啟動t細胞免疫應答反應，此外， dc與b細胞以及nk細胞等也存在著相互作用，可見， dc在連接天然免疫和獲得性免疫之間起著非常重要的作用。
  2. Most teratomas of the mediastinum are benign and only 15 - 20 % account for malignant neoplasms, such as immature teratomas, mature teratomas with malignant transformation, or teratomas concomitant to mixed germ cell tumors

    大部分縱膈腔畸胎瘤是良性的，百分之十五至二十是惡性腫瘤，如不成熟畸胎瘤、成熟畸胎瘤並惡性轉形、畸胎瘤共存的混合生殖細胞瘤。
  3. Cd 14 * monocytes or bone marrow derived hematopoietic progenitor cells cultured with granulocyte - macrophage colony - stimulating factor ( gm - csf ) and il - 4 differentiate into efficient apc with morphology and cell surface molecule expression typical of immature dc. it was demonstrated that a variety of factors ( such as lps, tnf - a, il - 1, monocyte - conditioned medium, and cd40 receptor cross - linking ) induce the maturation of immature dc to mature dc that are much more potent in activating t cells by increasing the expression of costimulatory molecules and cytokines, promoting the migration of dc to draining lymph nodes, and down - regulating the capacity of dc to capture and process antigen

    在體外，外周血cd14 ~ +單核細胞和cd34 ~ +骨髓造血前體細胞在粒細胞-巨噬細胞集落刺激因子（ granulocyte - macrophagecolony - stimulatingfactor ， gm - csf ）和il - 4的共同作用下可分化為未成熟dc ，未成熟dc具有強大的攝取和處理抗原的能力，但其抗原提呈能力較弱；未成熟dc在炎性細胞因浙江大竿俗士學位論文潛廷平子汐ilq ， yfax病原成分汐lpsx單核細胞條件培養液或cd40l等作用下可分化為成熟dc 。
  4. By nuclear transferee transfered the nih 3t3 cell to enucleated gv and mii oocyte. the immunofluorescence results showed that jak. 2 was not transfered to somatoblast nuclear whether the recombined oocyte occured gvbd or not. when transfered somatoblast nuclear to enucleated and integrated m ii oocyte, the immunofluorescence results showed that jak2 only existed in the nuclear of integrated m ii oocyte but not the somatoblast nuclear. the nuclear transfer implied that the mature and immature oocyte cytoplasm could not transfer the jak. 2 protein to donor nuclear

    通過核移植，將nih3t3體細胞核移入去核gv期和m期的卵母細胞中。熒光檢測發現，體細胞核與去核gv期卵母細胞質構成的重組卵無論是否發生gvbd ，核內均沒有jak2的出現。在去核和未去核的m期卵母細胞中移入體細胞核， jak2僅存在於未去核m期卵母細胞的核內，並不轉移到體細胞核內。
