The extract of each of the aforementioned five pathogenic Aspergillus spp. produced 2-11 specific antigen-antibody complexes after reacting with its homologous antiserum. Antisera prepared against extracts to these pathogenic aspergilli demonstrated variable intra-generic crossreactivity, which were eliminated by adsorption with heterologous Aspergillus spp. antigens. Fewer nonspecific reactions were noted with the reference antigen-antibody precipitates of A. nidulans and A. Terreus than with reference precipitates of the other Aspergillus spp. Exoantigen extracts of \"albino-type\" isolates of A. fumigatus produced two to five specific precipitins against anti-A. fumigatus serum only. Based on the specific reactions produced by the eight albino-type isolates and 1 Aspergillus sp. isolate, all these fungi were identified correctly and placed in the A. fumigatus group. Analyses of conventionally identified A. fumigatus, A. flavus, A. nidulans, A. niger, and A. terreus including an isolate of A. parasiticus, enabled us correctly to classify them (51/51, or 100%) into their respective groups. Specific Aspergillus spp. antigen-antibody precipitates were characterized and used as references in exoantigen tests. None of the fungi in the genera other than Aspergillus produced antigens identical to the selected reference antigens.</p>","PeriodicalId":77707,"journal":{"name":"Diagnostic immunology","volume":"4 2","pages":"112-6"},"PeriodicalIF":0.0,"publicationDate":"1986-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14217722","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}

{"title":"Restricted effector cell function in ADCC.","authors":"P R McConnachie,&nbsp;F Lower,&nbsp;J A McIntyre","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Human effector cell function in ADCC reactions was studied as a result of observations showing discrepant ADCC reactivities among different effector cell populations. Effector cells prepared from ten blood donors were tested individually and as a pool against a battery of nine antisera-target cell combinations in an 11-x-9 matrix. The results identified individuals with weak, intermediate, and strong effector cell functions; however, there was a wide range of ADCC reactivity by each person's effector cells against the nine targets. No single antibody-target cell combination was consistently subjected to the least kill or greatest kill by the different effector cell preparations. Pooled effector cell responses were found to be weaker than expected. There was no relationship of age or sex with effector cell function, but a trend was noted for strong and weak reactions to be associated with HLA-DR7 and DR1, respectively. Neither the sharing of HLA antigens between effector and target cells nor self ADCC reactivity could account for the variations in effector cell function. Exploratory principal components factor analysis suggested that recognition of antibody-target cell combinations by effector cells was represented by three major groupings. These data collectively indicate the existence of an allorestrictive Fc receptor recognition step in ADCC responses.</p>","PeriodicalId":77707,"journal":{"name":"Diagnostic immunology","volume":"3 2","pages":"67-74"},"PeriodicalIF":0.0,"publicationDate":"1985-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"15154728","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}

We therefore examined the ability of this flow cytochemistry system to predict allergic diathesis in vitro by examining the number of basophils detected before and after incubation with a variety of allergens. One hundred subjects with documented atopic reactions to known allergens were examined and compared to 13 patients who had undergone successful desensitization and 12 normal subjects who had no history of atopy. One subject who had a previous anaphylactic response to penicillin but was skin-test negative to the major antigenic determinant demonstrated 55% degranulation after incubation with penicillin G. Finally, the basophil degranulation as assessed by the Technicon H-6000 was compared to a histamine release assay to determine the sensitivity of the automated system.
