mortality/aging
• mean survival time following infecting with virulent Mycobacterium tuberculosis is 15 days compared to over 60 days for wild-type controls
• treatment with exogenous IFNG improves survival
• more than 70% of mice infected on the cornea with herpes simplex virus type 1 (HSV-1) at a dose of 105 TCID50 (50% tissue culture infective dose) infectious particles die

immune system
• in mice with acute or chronic HSV-1 infection the ratio of IgG2a to IgG1 is dramatically reduced compared to BALB/c wild-type mice
• following infection with type A influenza
• activated splenic and liver NK cells are less efficient in their killing of 4T1 or Renca tumor target cells
• T cells from mice immunized with myelin oligodendrocyte glycoprotein (MOG) peptide show more IL-17a expressing cells and greater IL-17a production after MOG restimulation than controls; IL-4 is not detectable in these cells
• the magnitude of the delayed type hypersensitive response in mice after HSV-1 infection is reduced compared to BALB/c wild-type controls
• following culturing of IL-17 producing T cells in vitro, IL-17 production is twice as high as in similarly treated wild-type cells
• the magnitude of the delayed type hypersensitive response in mice after HSV-1 infection is reduced compared to BALB/c wild-type controls (J:29170)
• display an increased IgG1 antibody response to type A influenza infection (J:110721)
• at 14 days after infection with virulent Mycobacterium tuberculosis, 10- 100 fold more viable bacteria are found in the organs compared to organs of wild-type controls
• at 14 days after infection with virulent Mycobacterium tuberculosis, about 90% of the granulomas in the liver and 20% of the granulomas in the spleen are necrotic
• treatment with exogenous IFNG decreases the bacterial load
• mean survival time following infecting with virulent Mycobacterium tuberculosis is 15 days compared to over 60 days for wild-type controls
• treatment with exogenous IFNG improves survival
• at 5 - 8 days post infection mice develop more severe conjunctivitis, periocular skin lesions, corneal opacity, and anterior chamber exudate following infection with HSV-1 relative to wld-type BALB/c controls infected with a higher dose of virus
• infectious virus is detected up to 10 days post infection with HSV-1 in mutants compared to up to 4 or days post infection in wild-type BAL/c mice or littermate controls, respectively
• more than 70% of mice infected on the cornea with herpes simplex virus type 1 (HSV-1) at a dose of 105 TCID50 (50% tissue culture infective dose) infectious particles die

vision/eye
• corneal injection of a plasmid encoding short hairpin RNA targeting the C terminus of the secreted form of Flt1 (pshRNA-sflt1) induces corneal vascularization within 3 days of injection in wild-type and mutant mice

homeostasis/metabolism
• T cells from mice immunized with myelin oligodendrocyte glycoprotein (MOG) peptide show more IL-17a expressing cells and greater IL-17a production after MOG restimulation than controls; IL-4 is not detectable in these cells

cardiovascular system
• corneal injection of a plasmid encoding short hairpin RNA targeting the C terminus of the secreted form of Flt1 (pshRNA-sflt1) induces corneal vascularization within 3 days of injection in wild-type and mutant mice

hematopoietic system
• in mice with acute or chronic HSV-1 infection the ratio of IgG2a to IgG1 is dramatically reduced compared to BALB/c wild-type mice
• following infection with type A influenza
• activated splenic and liver NK cells are less efficient in their killing of 4T1 or Renca tumor target cells
