Journal Article
Serum IgA preferentially binds to cationic polypeptides in IgA nephropathy.
TL;DR: When 18 patients with IgA-GN were tested after kidney transplantation, increased levels of cBSA-IgA and/or Ig a-RF were found to be associated with the recurrence of mesangial IgA deposits in the graft.
Journal ArticleDOI
Inhibition of matrix metalloproteinase-9 by interferons and TGF-β1 through distinct signalings accounts for reduced monocyte invasiveness
TL;DR: The data point out the importance of IFNs and TGF‐β1 in the control of monocyte MMP‐9‐mediated extravasation.
Journal ArticleDOI
Characterization of a recombinant proteinase 3, the autoantigen in Wegener's granulomatosis and its reactivity with anti‐neutrophil cytoplasmic autoantibodies

TL;DR: Improper disulfide bond formation and/or lack of post‐translational events in insect cells, may affect the conformation of PR3, precluding its reactivity with sera from WG patients.
Journal ArticleDOI
Isotype and affinity of anti-myeloperoxidase autoantibodies in systemic vasculitis.
Elisabeth Kokolina,Laure-Hélène Noël,P. Nusbaum,Christine Geffriaud,Jean-Pierre Grünfeld,Lise Halbwachs-Mecarelli,Philippe Lesavre +6 more
TL;DR: Anti-MPO IgG level increased during relapses but the affinity of these IgG autoantibodies remained low, and in a longitudinal study, high levels of anti-MPo IgM, when present, were observed early in the course of the disease and in some cases preceded the reappearance of pro-MPE IgG during relapse.
Journal ArticleDOI
Nonneoplastic circulating sézary‐like cells in cutaneous T‐cell lymphoma. Ultrastructural, immunologic, and T‐cell receptor gene‐rearrangement studies
Albert Bendelac,N.T.J. O'Connor,Marie-Thérèse Daniel,Christian Boitard,Catherine Michel,Liliane Laroche,Philippe Lesavre,Jean-François Bach +7 more
TL;DR: It is concluded that reactive nonneoplastic Sézary‐like cells may be present not only in various benign conditions, as previously known, but also in T‐cell lymphomas.
