Fibrinogen-reactive T cells transfer disease to naÃ¯ve mice

ABSTRACT: Splenocytes harvested from mice with FIA were cultured in vitro and stimulated with 0.01 mg/ml fibrinogen for 3 days. Enriched T cells were transferred into 6-week-old naÃ¯ve SJL mice, which developed visible signs of arthritis within 2 weeks. Synovial array profiling of plasma from the arthritic recipient mice demonstrated autoreactive B cell responses against peptides representing native fibrinogen, and further spreading of the responses to target collagen type V, cartilage gp39, and citrullinated vimentin. Custom-spotted protein slides were with plasma samples from individual mice. Four slides were probed with plasma derived from naÃ¯ve mice and five slides were probed with plasma derived from mice injected with FIA T cells.

Rheumatoid arthritis (RA) is an autoimmune synovitis characterized by the presence of anticitrullinated protein Abs, although the exact targets and role of anticitrullinated protein autoimmunity in the pathogenesis of RA remain to be defined. Fibrinogen, which can be citrullinated, has recently emerged as a candidate autoantigen. To determine whether autoimmunity against fibrinogen can mediate inflammatory arthritis, we immunized a variety of common mouse strains with fibrinogen and found that D ...[more]

Project description:Natural antibodies, which arise without known immune exposure, have been described that specifically recognize cells dying from apoptosis but their role in innate immunity remains poorly understood. Herein, we show that the immune response to neo-antigenic determinants on apoptotic thymocytes is dominated by antibodies to oxidation-associated antigens, phosphorylcholine (PC), a head group that becomes exposed during programmed-cell death, and malondialdehyde (MDA), a reactive aldehyde degradation product of polyunsaturated lipids produced following exposure to reactive-oxidation species. While natural antibodies to apoptotic cells in naM-CM-/ve adult mice were dominated by PC and MDA specificities, the amounts of these antibodies were substantially boosted by treatment of mice with apoptotic cells. Moreover, the relative amounts of PC and MDA antibodies was affected by VH gene inheritance. Antibody interactions with apoptotic-cells also mediated the recruitment of C1q, which alone can promote apoptotic-cell phagocytosis by immature dendritic cells. Significantly, IgM-antibodies to both PC and MDA were primary factors in determining the efficiency of serum-dependent apoptotic-cell phagocytosis. Hence, we demonstrate a mechanism by which certain natural antibodies that recognize neo-antigens on apoptotic cells, in naM-CM-/ve mice and those induced by immune exposure to apoptotic-cells, can enhance the functional capabilities of immature dendritic cells for phagocytic engulfment of apoptotic cells. Keywords: Natural antibodies, Inflammation, Complement, Apoptosis In the study presented here, a total of 11 custom-spotted protein slides were hybridized with a T15 IgM monoclonal antibody at three different concentrations, an isotype control IgM, 2 slides were hybridized with serum from naM-QM-^Wve mice, 2 slides incubated with serum from mice immunized with apoptotic cells, 2 slides were incubated with serum from mice immunized with saline, and a negative control slide with no antibody hybridized

Project description:Epitope mapping studies aim to identify the binding sites of antibody-antigen interactions to enhance the development of vaccines, diagnostics and immunotherapeutic compounds. However, mapping is a laborious process employing time- and resource-consuming M-bM-^@M-^Xwet benchM-bM-^@M-^Y techniques or epitope prediction software that are still in their infancy. For polymorphic antigens, another challenge is characterizing cross-reactivity between epitopes, teasing out distinctions between broadly cross-reactive responses, limited cross-reactions among variants and the truly type-specific responses. A refined understanding of cross-reactive antibody binding could guide the selection of the most informative subsets of variants for diagnostics and multivalent subunit vaccines. We explored the antibody binding reactivity of sera from human patients and Peromyscus leucopus rodents infected with Borrelia burgdorferi to the polymorphic outer surface protein C (OspC), an attractive candidate antigen for vaccine and improved diagnostics for Lyme disease. We constructed a protein microarray displaying 23 natural variants of OspC and quantified the degree of cross-reactive antibody binding between all pairs of variants, using Pearson correlation calculated on the reactivity values using three independent transforms of the raw data: (1) logarithmic, (2) rank, and (3) binary indicators. We observed that the global amino acid sequence identity between OspC pairs was a poor predictor of cross-reactive antibody binding. Then we asked if specific regions of the protein would better explain the observed cross-reactive binding and performed in silico screening of the linear sequence and 3-dimensional structure of OspC. This analysis pointed to the C-terminal helix of the structure as a major determinant of type-specific cross-reactive antibody binding. We developed bioinformatics methods to systematically analyze the relationship between local sequence/structure variation and cross-reactive antibody binding patterns among variants of a polymorphic antigen, and this method can be applied to other polymorphic antigens for which immune response data is available for multiple variants. Antibody profiling was performed on sera from Borrelia burgdorferi infected and non-infected humans and Peromyscus leucopus rodents against 23 variants of the surface protein OspC . For infected human serum samples, the OspC type of the infecting B. burgdorferi strain is unknown; for experimentally-infected P. leucopus serum samples, it is known. Of human serum samples, 55 were from infected individuals and 25 from naive controls. Of P. leucopus serum samples, 23 were from infected individuals and 7 were from naive controls.

Project description:Although natural antibodies (NAbs) are present from birth, little is known about what drives their selection, and whether they have housekeeping functions. We now show that the prototypic T15-NAb, first identified because of its protective role in infection, is representative of a previously unknown type of NAb response that specifically recognizes and forms complexes with apoptotic cells, and which promotes cell-corpse engulfment by phagocytes. This T15-NAb-mediated process is dependent on the recruitment of C1q and mannose-binding lectin (MBL), which have known immune modulatory activities that also provide âeat meâ signals for phagocytic clearance. Further investigation revealed that, the addition of T15-NAb significantly suppressed in vitro macrophage LPS-induced TNF-alpha and IL-6 secretion, as well as in vitro Toll-like receptor (TLR)-induced dendritic cell maturation and secretion of pro-inflammatory cytokines and chemokines. Significantly, high doses of this B-1 cell produced NAb also inhibited in vivo TLRâinduced pro-inflammatory responses, and could suppress autoimmune inflammatory arthritis. These studies identify and characterize a previously unknown regulatory circuit by which a NAb product of innate-like B cells aids homeostasis by control of fundamental inflammatory pathways.
