Formalin fixed melanoma cells either obtained from established cell lines or freshly excised tumors were used as antigen source. From a group of 33 melanoma patients 14 reacted positively (42%) when fixed cultured cells were used, whereas, no positive reactions were found in a group of 14 control donors. However, a considerable proportion of patients with chronic inflammatory processes of the skin reacted positively (4/17 = 24%). A smaller proportion of positive reactions were found in melanoma patients when fixed melanoma cells from excised tumors were used (1/16 = 6%). The positive results in the group with chronic inflammatory processes may be explained as reactions against melanoma associated, but not melanoma-specific, antigens. Three possible reasons are discussed for the low frequency of positive reactions with cells from excised tumors: 1. the cells used in this study display only a few of the antigenic determinants typical for malignant melanoma, 2. antigen expression is quantitatively lower. 3. the surface antigens are covered by blocking factors.</p>","PeriodicalId":23768,"journal":{"name":"Zeitschrift fur Immunitatsforschung, experimentelle und klinische Immunologie","volume":"151 3","pages":"242-9"},"PeriodicalIF":0.0,"publicationDate":"1976-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11353395","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}

Peripheral blood lymphocytes were isolated by Ficoll gradient centrifugation (fraction F); subsequently the phagocytic and adherent cells were removed and the supernating cell population (fraction fff) was passaged through IgG anti-IgG columns to obtain a B cell free lymphocyte suspension (fraction fff-c). cells from the 3 lymphocyte fractions and from defibrinated whole blood were simultaneously tested for cytotoxic activity against unsensitized IGR3 target cells (SCMC assay) and IGR3 cells perviously sensitized with a rabbit anti-melanoma IgG (ADCC assay). Dose-response curves were established with all lymphocyte fractions and with whole blood. The following results were obtained. 1. With all lymphocyte fractions tested, ADCC was approximately 15 time higher than SCMC, whereas with whole blood, the difference tended to be less pronounced. 2. Elimination of phagoctic and adherent cells had no significant effect on SCMC and ADCC. 3. Passage over IgG anti-IgG columns drastically reduced cytotoxicity in both assays without, however, completely abolishing it. 4. The only difference seen between lymphocyte cytotoxicity of melanoma patients and control persons was a slight, but non-significant depression of SCMC and ADCC in melanoma patients. The results confirm and extend our previous report that SCMC against an allogeneic tumor cell-line is due to not-specific \"Null\" or \"K\" cell-activity rather than to specific T cell cytotoxicity.

Different incubation periods resulted in erythrocyte preparations with different hapten density. Complement dependent lysis induced by IgM or IgG antibodies was studied with the cell preparations. The calculation of hapten density on the erythrocyte surface was not possible by direct measurement of coupled radioactive BPO since more than 90% of radioactive material was found in the soluble supernatant after osmotic cell lysis and less than 10% was fixed to the cellular membrane. Measurement of membrane bound immunologically relevant BPO-groups was achieved, therefore, by comparison of the inhibitory capacity of the test cells with that of a standard cell preparation. The latter consisted of tannic acid treated erythrocytes coated with protein complexed radioactive BPO. Surface hapten density of the different target cell preparations varied between 1.9 x 10(5) and 4.8 10(5) BPO-groups per cell depending on the time of incubation. Complement dependent antibody mediated cell lysis was significantly reduced by reduction of haptenic sites per target cell, IgG induced lysis being much more affected than hemolysis induced by IgM antibodies. Statistical calculations led to the conclusion that 18,000 protein islets per cell bearing 4 or more BPO-groups are not sufficient for hemolysis induced by IgG antibodies. 48,000 protein islets with this hapten density are necessary for \"optimal\" sensitization.
