immune system
• APC/OVA primed peripheral CD8+ cells have significantly enhanced cytolitic efficiency
• under nonpolarizing conditions, IFNgamma levels are higher
• following infection with Alu/NP-CGG, B cell germinal centers are reduced 3-fold
• following infection with Alu/NP-CGG, Th2 cytokine levels are reduced
• following infection with Alu/NP-CGG, lower levels of IL-4, IL-5, and IL-13 are produced
• under nonpolarizing conditions, markedly lower levels of IL-4, IL-5, and IL-13 are produced
• following infection with S. mansoni, mice have smaller granulomas and somewhat reduced levels of eosinophils in the lung and significantly reduced levels of IL-13 Ralpha2 in serum
in vitro exposure of lymph nodes with ConA or Schistosome egg antigen results in a reduced production of IL4 and IL5 and reduced proliferation of T cells
