  • IUPAC Glossary of Terms Used in Immunotoxicology (IUPAC Recommendations 2012)*
    Pure Appl. Chem., Vol. 84, No. 5, pp. 1113–1295, 2012. http://dx.doi.org/10.1351/PAC-REC-11-06-03 © 2012 IUPAC, Publication date (Web): 16 February 2012 IUPAC glossary of terms used in immunotoxicology (IUPAC Recommendations 2012)* Douglas M. Templeton1,‡, Michael Schwenk2, Reinhild Klein3, and John H. Duffus4 1Department of Laboratory Medicine and Pathobiology, University of Toronto, Toronto, Canada; 2In den Kreuzäckern 16, Tübingen, Germany; 3Immunopathological Laboratory, Department of Internal Medicine II, Otfried-Müller-Strasse, Tübingen, Germany; 4The Edinburgh Centre for Toxicology, Edinburgh, Scotland, UK Abstract: The primary objective of this “Glossary of Terms Used in Immunotoxicology” is to give clear definitions for those who contribute to studies relevant to immunotoxicology but are not themselves immunologists. This applies especially to chemists who need to under- stand the literature of immunology without recourse to a multiplicity of other glossaries or dictionaries. The glossary includes terms related to basic and clinical immunology insofar as they are necessary for a self-contained document, and particularly terms related to diagnos- ing, measuring, and understanding effects of substances on the immune system. The glossary consists of about 1200 terms as primary alphabetical entries, and Annexes of common abbre- viations, examples of chemicals with known effects on the immune system, autoantibodies in autoimmune disease, and therapeutic agents used in autoimmune disease and cancer. The authors hope that among the groups who will find this glossary helpful, in addition to chemists, are toxicologists, pharmacologists, medical practitioners, risk assessors, and regu- latory authorities. In particular, it should facilitate the worldwide use of chemistry in relation to occupational and environmental risk assessment.

  • A Novel Lymphocyte Transformation Test (LTT-MELISAR) for Lyme Borreliosis
    Diagnostic Microbiology and Infectious Disease 57 (2007) 27–34 www.elsevier.com/locate/diagmicrobio A novel lymphocyte transformation test (LTT-MELISAR) for Lyme borreliosis Elizabeth Valentine-Thona,4, Karsten Ilsemannb, Martin Sandkampc aDepartment of Immunology, Laboratory Center Bremen, 28205 Bremen, Germany bDepartment of Serology in Laboratory Center Bremen, 28205 Bremen, Germany cLaboratory Center Bremen, 28205 Bremen, Germany Received 18 April 2006; accepted 7 June 2006 Abstract Diagnosis of active Lyme borreliosis (LB) remains a challenge in clinically ambiguous, serologically indeterminant, and polymerase chain reaction-negative patients. Lymphocyte transformation tests (LTTs) have been applied to detect specific cellular immune reactivity, but their clinical application has been severely hampered by the poorly defined Borrelia antigens and nonstandardized LTT formats used. In this study, we describe the development and clinical relevance of a novel LTT using a validated format (MELISAR) together with well-defined recombinant Borrelia-specific antigens. From an initial screening of 244 patients with suspected Borrelia infection or disease, 4 informative recombinant antigens were selected: OspC (Borrelia afzelii), p41-1 (Borrelia garinii), p41-2 (B. afzelii), and p100 (B. afzelii). Thereafter, 30 seronegative healthy controls were tested in LTT-MELISAR to determine specificity, 68 patients were tested in parallel to determine reproducibility, and 54 lymphocyte-reactive symptomatic patients were tested before and after antibiotic therapy to assess clinical relevance. Most (86.2%) of the 36.9% (90/244) LTT-MELISAR-positive patients were seropositive and showed symptoms of active LB. Specificity was 96.7% and reproducibility 92.6%. After therapy, most patients (90.7%) showed negative or markedly reduced lymphocyte reactivity correlating with clinical improvement.

  • Use of Monoclonal Antibodies in an ELISA to Detect Igm Class Antibodies Specific for Toxoplasma Gondii
    J Clin Pathol: first published as 10.1136/jcp.40.8.853 on 1 August 1987. Downloaded from J Clin Pathol 1987;40:853-857 Use of monoclonal antibodies in an ELISA to detect IgM class antibodies specific for Toxoplasma gondii A H BALFOUR, J P HARFORD, MARGARET GOODALL* From the Toxoplasma Unit, The Regional Public Health Laboratory, Leeds, and the *Department of Immunology, The Medical School, Birmingham SUMMARY Two monoclonal antibodies CH6 and Cl E3 were used in an antibody class capture assay for the detection of IgM antibodies specific for Toxoplasma gondii. CH6 was used on the solid phase to capture human IgM. After a Toxoplasma gondii antigen had been added, specifically bound material was detected using Cl E3 coupled to horseradish peroxidase. The assay was compared with an established system using polyclonal antisera at both the capture and antigen detection stages. A good correlation was found, with 97 3% (125 of 128) of sera giving the same classification in both assays. Three sera were positive only in the polyclonal system. No false positive results were found when 118 negative sera were examined. The two monoclonal antibodies provide a viable alternative to the use of polyclonal sera at the capture and antigen detection stages in the antibody class capture assay for the measurement of specific IgM against Tgondii. copyright. In many infectious diseases the presence of specific two reverse immunosorbent methods for specific IgM antibodies of the IgM class allows a diagnosis to be detection, it was not used in an enzyme linked immu- made from a single serum specimen taken early in nosorbent assay (ELISA) system.7 8 In this study an infection.
