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。

Upon CV and DPV experiments, the reduction and oxidation potential of these porphyrins were shown to be similar to each other. This suggests that different PAHs ethynyl substitutes would have similar effects on electrochemical properties of the porphyrin molecule.

在电化学探讨部份，接上不同多环芳香族取代基的紫质分子之氧化还原电位彼此都相当类似，表示这些紫质光敏剂的能隙相当接近，不同的多环芳香族取代基对於紫质分子的电化学性质影响程度相当接近。

In the first part, one of the side-arms of hexakisbenzene was replaced with a 4-pyridinylethynyl group. Comparing with analogous compounds incorporating a 2- or 3-pyridinylethynyl moiety, the compound with a 4-pyridinyl -ethynyl unit shows lowest melting and clearing points.
