In situ detection of autoanti-idiotype antibody-forming cells induced by influenza virus infection.
In situ immunocytochemical-staining methods combined with computer-aided image analysis were employed to examine autoanti-idiotype antibody-forming cell expansion in vivo. Autoanti-idiotype antibody-forming cells were demonstrated in the spleens of C57BL/6J (B6) strain mice intranasally infected with the influenza virus A/Hong Kong/168/(H3N2)[R] X-31. Autoanti-idiotype B cells were detected and elevated in spleen tissues after secondary influenza infections compared to normal B6 mice, and were specific for a dominant idiotype antibody called PY206 reactive with the influenza virus hemagglutinin. Influenza virus-infected BALB/c mice, which make little PY206 Id, did not have increased autoanti-Id against PY206 compared to normal mice. Results provide evidence for an idiotype network-mediated stimulation of autoanti-idiotype B cell production during influenza virus infection.
