phenotype observed in females
phenotype observed in males
N normal phenotype
respiratory system
• after 4 weeks, mice show absence of vascular remodeling of the airways in response to Mycoplasma pulmonis infection wherease wild-type show complex growth and reorganization ot the vascular beds
• abnormalities in epithelial cell differentiation and mucus secretion are intermediate between wild-type and Igh-6 deficient mice after M. pulmonis infection

immune system
N
• proliferation of intestinal epithelial cells (IECs) and MHC class II expression on IECs is comparable to controls
• mice do not produce IgG following infection, although M. pulmonis-specific IgM antibodies are detected
• bacteria are present in liver and kidney of mice after 4 weeks of M. pulmonis infection, but bacteria are absent from wild-type mouse tissue
• airway vascular and airway lymphatic vessel remodeling are impaired or absent compared to wild-type mice after M. pulmonis infection

hematopoietic system
• mice do not produce IgG following infection, although M. pulmonis-specific IgM antibodies are detected

N
• mice have same numbers of B cells in spleen and lymph nodes as control littermates
• transgenic B cells increase in size and show upregulated MHC class II when mice are injected with T cells
• mice show a substantial decrease in B220+ cells in bone marrow when mice receive nontransgenic T cells
• when syngeneic wild-type T cells are transferred into Tcrb-deficient transgenic hosts, after 3 weeks the number of B cells in peripheral lymphoid tissues is decreased by ~50% compared with Tcrb-deficient mice not injected with T cells
