To develop monoclonal reagents for antigenic analysis and serotyping of Campylobacter spp., hybridoma cell lines were produced by fusion of mouse myeloma cells and spleen cells from mice immunized with Formalin-treated Campylobacter jejuni organisms. An enzyme immunoassay was used for preliminary screening of the cell culture supernatants and ascites. Twenty-nine clones which reacted with the i...
Hybridomas secreting monoclonal antibodies that reacted with a 45 000 dalton surface polypeptide and major immunogen of T pallidum were produced. This polypeptide was also found in T pertenue but not in T hyodysenteriae or T phagedenis biotype Reiter.
We reasoned that immune complex (IC)-bearing follicular dendritic cells (FDCs) promote somatic hypermutation (SHM). This hypothesis was tested in murine germinal center reactions induced in vitro by coculturing 6-day (4-hydroxy-3-nitrophenyl) acetyl-primed but unmutated lambda+ B cells, chicken gamma-globulin (CGG) memory T cells, FDCs, and ICs (anti-CGG plus NP-CGG). Mutations in primed lambda...
An enterocolitis has been induced in guinea pigs by alloimmunisation with a mucosal protein. A single dose of immunogen fails to provoke a synthesis of precipitant antibodies, but a high percentage of animals, injected with two or more doses, develop these antibodies. A specific cell mediated immune response was already detectable 30 days after a single dose of immunogen. At later periods and a...
Immunotherapies for various neurodegenerative diseases have recently emerged as a promising approach for clearing pathological protein conformers in these disorders. This type of treatment has not been assessed in models that develop neuronal tau aggregates as observed in frontotemporal dementia and Alzheimer's disease. Here, we present that active immunization with a phosphorylated tau epitope...
