      Can Impart Th1 Immunity to Th2-Biased Recipients.

AB  - We have previously demonstrated lactational transfer of T cell-based immunity
      from dam to foster pup. In the short term, a significant part of transferred
      immunity is passive cellular immunity. However, as time progresses, this is
      replaced by what we have described as maternal educational immunity such that by 
      young adulthood, all immune cells responding to a foster dam immunogen are the
      product of the foster pup's thymus. To reduce confounding factors, this original 
      demonstration used congenic/syngeneic dam and foster pup pairs. In this study, we
      investigated lactational transfer of immunity to Mycobacterium tuberculosis in
      MHC class I-mismatched animals, as well as from Th1-biased dams to Th2-biased
      foster pups. Using immunized C57BL/6J dams, lactational transfer to nonimmunized 
      BALB/cJ foster pups resulted in much greater immunity than direct immunization in
      5-wk-old pups (ex vivo assay of pup splenocytes). At this age, 82% of
      immunogen-responding cells in the pup spleen were produced through maternal
      educational immunity. FVB/NJ nonimmunized foster recipients had a greater number 
      of maternal cells in the spleen and thymus but a much larger percentage was
      Foxp3(+), resulting in equivalent immunity to direct immunization. Depletion of
      maternal Foxp3(+) cells from pup splenocytes illustrated a substantial role for
      lactationally transferred dam regulatory T cells in suppression of the ex vivo
      response in FVB/NJ, but not BALB/cJ, recipients. We conclude that lactational
      transfer of immunity can cross MHC class I barriers and that Th1 immunity can be 
      imparted to Th2-biased offspring; in some instances, it can be greater than that 
      achieved by direct immunization.
