    Abstract Introduction: Allergen-specific CD4+ T cells play a central role in autoimmune disorders, allergies and asthma, with Th2-type immunity being the typical functional response of CD4+ T cells. This study aimed to investigate the role of MBD2 in regulating Th2 cell differentiation. Methods: Splenic mononuclear cells were extracted from C57BL/6 mice, and CD4+ T cells were isolated using magnetic beads and confirmed through flow cytometry. Lentivirus was employed to construct MBD2-silenced CD4+ T cells. In vitro experiments were performed to treat splenogenic mononuclear cells and CD4+ T cells with Ovalbumin (OVA), and Th2 cell ratios and IL-4 levels were assessed… More >

    Abstract The mechanisms through which maternal immunization can modulate offspring thymic maturation of lymphocytes are not fully understood. Here, we aimed to evaluate whether maternal OVA-immunization can inhibit the maturation of Th17 cells on offspring thymus. C57BL/6 females were immunized with OVA in Alum or Alum alone and mated with normal WT males. Offspring thymus was evaluated at three or 20 days of age. The demonstration that maternal OVA-immunization can inhibit offspring allergy development validated our experimental protocol. First, we observed that maternal OVA-immunization can inhibit the expression of RORγt and IL-17 molecules on immature T More >
