Gluten-specific CD4+ T-cells of patients affected by Celiac disease show an high production of interferon-gamma (IFN-γ) and a low production of Bach2. CD4+ T-cells proliferate and differentiate into various subtypes in response to antigen (Ag) stimulation and their microenvironment. IFN-γ is known to promote the differentiation of T-helper 1 (TH1) cells, inhibit the TH2 immune response and Treg survival, and activate the phagocytosis of macrophages, B-cell immunoglobulin class switching, and presentation of major histocompatibility complexes (MHCs). Bach2 expression is crucial for the development of Treg and for the germinal center formation, somatic hypermutation and class-switch recombination of immunoglobulins in B-cells; thus is an important key regulator in the maintenance of immune homeostasis.
