Abstract
Untersucht wurden Auftreten und Verhalten von komplementbindenden Anti-Kaninchen-ROS-Antikörper im Serum von GrCh-Kaninchen nach ein- oder zweimaliger intracutaner Applikation retinaler Antigene in komplettem Freundschen Adjuvans (KFA). Die Wirkungen von 14 Antigen-Varianten aus heterologen, homologen und autologen Netzhaut-Komponenten in KFA wurden geprüft und verglichen. Mit Ausnahme des Überstandes eines zentrifugierten Homogenisats homologer Retina bewirkten alle übrigen Immunogene generell das Auftreten von Anti-ROS-Antikörpern. Die niedrig bleibenden Titer-Maxima waren 4 bis 8 Wochen post injectionem überschritten. Die Titer-Bewegungen zeigten Beziehungen zur Qualität und Dosierung der Immunogene. Boosterungseffekte nach Reinjektion erreichten ihr Maximum bereits nach 5 bis 14 Tagen. Tiere, die keine Chorioretinitis-Herde ausbildeten, hatten öfter höhere Antikörper-Titer als Kaninchen mit klinisch festgestellter Erkrankung. Unter der Voraussetzung entsprechender Relevanz der beobachteten humoralen Reaktion haben die nachgewiesenen komplementbindenden Antikörper gegen homologe ROS eher protektive als pathogene Funktion. The authors studied the appearance and behavior of complement-fixing anti-ROS antibodies in the sera of GrCh rabbits following one or two intracutaneous injections of retinal antigens emulsified in Freund's complete adjuvant (KFA). Fourteen different antigenic preparations from heterologous, homologous, and autologous retinal components incorporated in KFA were tested and compared. Apart from the supernatant of a centrifuged homogenized preparation of homologous retina, all immunogens generally induced anti-ROS antibodies. The antibody titers (reciprocal values) reached a maximum 4 to 8 weeks post injection, at only low levels. The changes in antibody concentrations showed some relationship to the quality and dose of the immunogens. Anamnestic effects following reinjection reached maximum values within as little as 5 to 14 days. Animals not developing chorioretinitic lesions showed higher antibody titers more frequently than rabbits with clinically confirmed disease. Provided there is sufficient relevance of the humoral reactions observed, the complement-fixing antibodies we found in our experiments are more likely to have protective than pathogenic functions.This publication has 9 references indexed in Scilit:
