Compared with classical cytotoxic T lymphocytes , NK cells are superior in the following aspects: NK cells are among the first cell types to be activated after intracellular pathogen stimuli, the activity of NK cells peaked between 1 to 3 days, retained during the first 7-10 days, and the T cells response emerged only after 7 days when the NK cell responses begin to decline; though comprising of only 10%-15% of peripheral lymphocytes, NK cells mobilize most of the cell populations in a strong and high level response to different invasions, and act as key factors at early defense before a specific immune response could mount, while only certain clones were involved in T cell response; NK cells kill virus-infected or malignant transformed cells without pre-sensitization and without restriction by major histocompatibility antigen, which is usually a mechanism of immune escape to T cell recognition by virus-infected or tumor cells, thus NK cell in complementary with T cells play crucial roles in tumor and virus eradication.
NK细胞以其强大的细胞毒活性为特征,与细胞毒性T细胞相比,NK细胞具有如下特点:NK细胞虽然只占外周血淋巴细胞的10-15%,但是对刺激性因素产生应答的过程十分迅速,一次可以调动大多数细胞共同参与,而不是几个克隆的活化,免疫应答的强度高;病毒感染或恶性转化细胞的一个主要特征是细胞表达的MHCⅠ类分子下降或消失,并借助这一机制逃避特异性T细胞应答的识别,NK细胞介导的杀伤活性无需抗原刺激,不受MHCⅠ分子表达的限制,从而与T细胞应答互为补充发挥免疫防御的功能;NK细胞的免疫活性可以被多种细胞因子上调,其中IFNα,IL-2,IL-12,IL-15和IL-18具备更强的作用;NK细胞具有强大的细胞因子分泌功能,对于启动T细胞特异性应答必不可少。

That means Pho85 kinaseand calcineurin were involved in salt tolerance with an identical target protein or in 中科院上海生化与细胞所博士学位论文摘要 the same pathway. Inhibition of calcineurin decrease the YPH499, pho80? mutant,and pap1 (pcl7)? mutant Mn2+ tolerance but not that of pho85? mutant and thepho85? mutant was more sensitive to Mn2+ than YPH499, pho80? mutant, and pap1(pcl7)? mutant even with the addition of cyclosporin A. Therefore, the conclusioncould be drawn that PHO85 gene played a dominant role in Mn2+ homeostasisregulation in compare with calcineurin.

The morphology and structure of reconstructed tissue was detected by microscope and scanning electron microscope.Results:(1) Compared with the control group, the cellular proportion of laminin group increased in 62 ~M phase, and decreased in Go~Gi phase significantly. As shown by the microscope, the cells of control group were in low density. The cells in mass connected tightly. The microfilament appeared reticular formation. The nucleus were the same in size. The cells of laminin group were in high density and put out so many lamellipodia, filopodia, which connected with the surrounding cells. The microfilament increased, elongated, and changed from reticulodromous to sarciniform, which reached to the pseudopods. The nucleus were different in size .(2) As shown by the inverted microscope and the cell growth curve, comparing with the controlgroup, cells of each test group increased evidently. The cellular proportion of each test group increased in S phase and G2 ~M phase, and decreased in Go~Gi phase significantly, but there was no considerable interations between LN and EGF;(3) As shown by the morphological observations, the cultured cat corneal endothelial cells formed an integrated membrane, and attached to the Descemets membrane closely, which was similar to the natural tissue. The cells connected tightly to each other, and some of them arranged in hexagon approximately.
