immune system
• significant increase in IgA levels in response to NP-KLH immunization, 3 fold increase in IgA levels in unimmunized mice and an increase in the levels of IL-4 and TGF beta/IL-5 dependent IgA isotype
• significant increase in total IgG and IgG1 levels in response to NP-KLH immunization and an increase in the levels of IL-4 and TGF beta/IL-5 dependent IgG1 isotype
• T cells exhibit enhanced immune responses
• increase in production of IFN-gamma by T cells in response to TCR stimulation
• increase in production of IL-2, IL-4, and IL-5 by T cells in response to TCR stimulation
• exhibit enhanced effector immune response, however T and B cell development is normal
• duodenum/proximal jejunum exhibits crypt hyperplasia, marked lymphocytic infiltration of the lamina propria, and moderate to severe villus destruction
• 60% exhibit ileum inflammation and display expansion of the lamina propria, crypt enlargement, and altered epithelial cell morphology or damage
• inflammatory infiltrates consist of T and plasma B cells
• 70% exhibit inflammatory infiltrates in the liver consisting of infiltrates present around hepatic vessels and granulomas arising as multiple foci within the parenchyma
• lung is less affected than intestine, kidney, or liver
