immune system

• Th2 immune response is not different from controls in mast cell-deficient animals
• IgM, IgG1, IgG2a, IgG2b, IgG3, IgA and IgE serum titers are not different from controls
• mice injected with K/Bxn serum in an antigen-induced arthritis model develop arthritis with rapid onset and similar severity relative to controls
• mice have a normal T cell-dependent antibody response to immunization with NP-chicken gamma globulin
• mice show reduced numbers of splenic basophils
• mice exhibit complete absence of mast cells in the peritoneum, skin and other tissues that normally contain mast cells
• peritoneal and skin mast cell numbers are partially rescued on a Trp53-null background
• mice show a complete lack of mast cells in the skin following repeated exposure to the inflammatory agent phorbol myristate acetate (PMA) whereas Kit mutants exhibit a 10-100-fold increase in mast cell numbers in the skin following exposure to PMA for 6 weeks
• after infection with helminthes, mice show no mucosal mast cell response in the intestine

hematopoietic system
N
• hematological parameters (counts of total white blood cells, red blood cells, platelets, hematocrit, and percentages of lymphocytes, monocytes, and neutrophils) are not affected in mutants
• mice show reduced numbers of splenic basophils
• mice exhibit complete absence of mast cells in the peritoneum, skin and other tissues that normally contain mast cells

• thymus cellularity is reduced 65% compared to age-matched controls
• some CD19lo thymic B cells have recombined Tcrb Dbeta1-Jbeta1 gene segments
• the percentage of thymocytes in the DN stages of T cell development are reduced compared to controls
• the percentage of thymocytes in the DN1 stage is reduced by a third with most of the reduction occurring at the DN1a and DN1b sub-stages
• the percentage of thymocytes in the DN2-DN3 stages are reduced by about 50% compared to controls
• double positive thymocytes make up just 65% of total thymocyte population compared to 80% in controls
• percentages of single-positive cells are increased in the thymus compared to controls
• 10-fold more B cells are found in the thymus compared to controls
• these B cells consist of a major CD19hi population and a minor CD19lo population with similar populations found in the bone marrow
• the CD19hi B cell population expresses cell surface markers similar to mature B2 B cells
• the CD19loB cell population have cell surface markers of pro- and pre- B cells
• single cell genotyping reveals about 94% of the CD19lo population has cre-mediated deletion of the floxed allele while only 26% of the CD19hi allele had the flox allele deleted
• the presence of recombined Tcrb gene segments in the abnormal CD19lo thymic B cells population suggests that the B cells differentiate from a DN1 T cell precursor
