  • Title: Dysregulation of T Follicular Helper Cells in Lupus.
    Author: Mountz JD, Hsu HC, Ballesteros-Tato A.
    Journal: J Immunol; 2019 Mar 15; 202(6):1649-1658. PubMed ID: 30833421.
    Abstract:
    Although multiple and overlapping mechanisms are ultimately responsible for the immunopathology observed in patients with systemic lupus erythematosus, autoreactive Abs secreted by autoreactive plasma cells (PCs) are considered to play a critical role in disease progression and immunopathology. Given that PCs derive from the germinal centers (GC), long-term dysregulated GC reactions are often associated with the development of spontaneous autoantibody responses and immunopathology in systemic lupus erythematosus patients. In this review, we summarize the emerging evidence concerning the roles of T follicular helper cells in regulating pathogenic GC and autoreactive PC responses in lupus.
