The Modulating Influence of Cyclic Nucleotides upon Lymphocyte-mediated Cytotoxicity
The capacity of allosensitized thymus-derived lymphocytes to destroy target cells bearing donor alloantigens is modulated by the cellular levels of cyclic AMP and cyclic GMP. Increases in the cyclic AMP levels of attacking lymphocytes by stimulation with prostaglandin E(1), isoproterenol, and cholera toxin inhibit lymphocyte-mediated cytotoxicity; whereas, depletion of cyclic AMP with imidazole...
متن کاملLymphocyte-mediated Cytotoxicity in Vitro
The ability of antisera to suppress immune responses either in vivo or in vitro is well known. A variety of lymphocyte-target cell systems have been employed to demonstrate inhibition of cell-mediated immunity by antisera in vitro, and skin, tumor, and kidney graft survival have been prolonged by passively administered antiserum in vivo. An in vitro lymphocyte-tumor cell assay system was develo...
متن کاملIsoantiserum-augmented development of lymphocyte-mediated cytotoxicity
Passive administration of anti-P-814 isoantiserum (IS) with P-815 mastocytoma was shown to augment the development of T-lymphocyte-mediated cytotoxicity (LMC). The LMC activity augmented by IS was specific to immunizing tumor cells, but required the simultaneous administration of P-815 tumor cells and anti-P-815 serum, suggesting that the antigen-antibody complex is involved in the development ...
متن کاملMolecular mechanisms of lymphocyte-mediated cytotoxicity.
Granule-mediated cytotoxicity is the major mechanism for lymphocytes to kill viruses, intracellular bacteria and tumors. The cytotoxic granules move to the immunological synapse by exocytosis after recognition of a killer cell. The contents of the granules are delivered into target cells with the help of perforin by endocytosis. A group of serine protease granzymes cleave their critical substra...
متن کاملthe influence of the neo-platonic concept of poetic imagination on wordsworth’s poetry
بر اساس نظریه افلاطون در باره شعر خلاقیت هنری مورد انتقاد قرار گرفته است. نظریه کلی در مورد شعر این بود که شعر از ظواهرتقلید میکند و نه حقیقت. چون سایه ای از حقیقت است. اما با پیدایش فلسفه نو افلاطونی، انتقاتات قبلی در مورد شعر و شاعری اصلاح شد. فلوطین در کتاب انئید، اساس خلق هنری را بر محور مُثل افلاطونی قرار داد. وی باور داشت که هنر مندان در خلق آثار هنری، تحت تاثیر مُثل افلاطونی بوده و عوالمی ...
