Summary: | [...]we generated pure T- and B-cell lines from our cohort and analyzed their intracellular C3 content by flow cytometry using specific mAb against 2 C3-associated neoepitopes (see Fig E4 in this article's Online Repository at www.jacionline.org). Analysis and gating strategy for CD8+ T-cell subsets was performed as previously described.E4,E5 Proliferation in response to mitogens and antibody titers PBMCs were stained with carboxyfluorescein succinimidyl ester (from Molecular Probes, Eugene, Ore) and cultured in RPMI-1640 supplemented with 10% FBS for 5 days after stimulation with 1 μg/mL plate-coated anti-CD3 (UCHT-1, OKT3; eBioscience, Waltham, Mass), 5 μg/mL Phaseolus vulgaris leucoagglutinin (PHA), 10 ng/mL phorbol 12-myristate 13-acetate and 1 μM ionomycin, 8 μg/mL Phytolacca americana pokeweed mitogen (PWM) (Sigma-Aldrich, St Louis, Mo), or 10 ng/mL superantigens (Staphylococcal Enterotoxin B or E; Toxin Technology, Inc, Sarasota, Fla). Generation of transformed T- and B-cell lines Human T-cell lymphotropic virus type 1-transformed T-cell lines, which have been reported to synthesize higher intracellular C3 than resting or activated primary T cells,E7 were generated as reported,E8 and maintained in RMPI-1640 supplemented with 10% FBS, 1% l-glutamine, 1% Antibiotic-Antimycotic (Gibco, Waltham, Mass), and 100 IU/mL recombinant human IL-2 (provided by Craig W. Reynolds, Frederick Cancer Research and Development Center, National Cancer Institute, National Institutes of Health, Frederick, Md).
