Production of autoantibodies by human-human hybridomas.
Peripheral blood lymphocytes and splenocytes of patients with autoimmune disease were used to prepare human-human hybridomas that produce autoantibodies. Because exogenous immunization was not used, the hybridoma antibodies were derived from B cells that spontaneously produced autoantibodies. 108 hybrids grew from 4,254 wells (2.5%). Optimal conditions for obtaining hybridomas with the GM 4672 ...
متن کاملPlatelet binding properties of monoclonal lupus autoantibodies produced by human hybridomas.
The platelet binding properties of human monoclonal lupus autoantibodies have been studied. These IgM autoantibodies, produced by human X human hybridomas derived from lymphocytes of patients with systemic lupus erythematosus, are known to bind to single-stranded DNA. Four anti-DNA antibodies that express the dominant 16/6 idiotype--HF2-1/17, HF2-18/2, HF2-1/13b, and HF3-16/6--bound to glutaral...
متن کاملMonoclonal lupus autoantibody secretion by human-human hybridomas. Selection of hybrids by conventional and novel techniques.
Autoantibody-secreting hybridomas were produced by somatic cell fusion of B lymphocytes from a patient with systemic lupus erythematosus with two different human myeloma lines. Selection of hybrids formed from one of these cell lines was performed by using aminopterine-containing culture medium as this cell line was deficient in hypoxanthine-guanine-phosphoribosyl transferase (HGPRT). The secon...
متن کاملHuman-human hybridomas producing monoclonal antibodies of predefined antigenic specificity.
We report the establishment of human-human hybridomas producing monoclonal antibody of predefined antigenic specificity. The U-266 human myeloma cell line was incubated in the presence of 8-azaguanine, and a rapidly growing, 8-azaguanine-resistant, hypoxanthine/amethopterin/thymidine (HAT) medium-sensitive mutant line, U-266AR1, was selected. These cells were fused with lymphoid cells from unin...
متن کاملO7: Functional Characterization of Human GABAA Autoantibodies in the Context of Limbic Encephalitis
Limbic encephalitis is an adaptive autoimmune disease, induced by different autoantibodies, which target extracellular neuronal epitopes, such as NMDA or GABAB receptors1,2. Recently our group found another human antibody, which binds to the α1 subunit of the GABAA receptor. Since the GABAA receptor is responsible for the majority of fast inhibitory neurotransmission, we investigated chan...
