Different surface molecules are known, which trigger the process of cell activation after binding of the respective ligands, including the T-cell-receptor/CD3 complex, the CD2 and the CD4 molecules. This surface molecules induce among other cellular events the expression of additional receptors, such as IL-2-receptors and Transferrin-receptors. The structure of these surface molecules, their possible functions and involved mechanisms of signal transmission from the membrane to the level of gene expression are presented. The different mechanisms of signal transmission and structures involved, such as the G-protein, are discussed. The different systems of signal transmission, in which such enzymes like Ca2+-dependent neutral Protease, Phospholipase C, Adenylatcyclase, Phospholipase A2 and Proteinkinases are involved, can interact. The regulation of the proliferation of T-cells is the result of a common action of different lymphokines, but also of growth factors from non-immune cells.</p>","PeriodicalId":7505,"journal":{"name":"Allergie und Immunologie","volume":"35 2","pages":"79-99"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13814793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some of these immunotherapeutic models are restricted to bladder cancer; the others have a generalized meaning. One model, restricted to bladder cancer, is based on the enzymatic++ pretreatment of effector-cells (macrophages, NK-cells), followed by their instillation in the patient's bladder. The other bladder tumor restricted model includes the direct in situ activation of effector cells by proteases and lipases. A third model for the treatment of bladder tumor implies a presensitization of patient's TD/TDTH-cells, followed by the treatment of patient's bladder tumor cells by some, common haptenic group. In addition, some novel ways of immune stimulation, partly by circumventing the (tumor-specific) immune tolerance, based on the cross-linking of crucial membrane structures on T4- and T8-cells or on a managed, controlled APC: T-cell interaction, are discussed. The details inclusively the comprehensive special literature can not be brought in this review article; they should be dealt with in special papers being in preparation.</p>","PeriodicalId":7505,"journal":{"name":"Allergie und Immunologie","volume":"35 4","pages":"249-63"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13719158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
