• mice survive infection with M. tuberculosis for the period of observation (day 50), whereas Ifng-null animals all succumb rapidly to infection
• neutralization of Ifng in infected mice abolishes the resistance to infection displayed by untreated mice

digestive/alimentary system
• in this animal model of colitis, less severe pathological injury is observed in mice receiving Tg(CD2-Caecam1*4L)1Rsb T cell transfer

immune system
• in this animal model of colitis, less severe pathological injury is observed in mice receiving Tg(CD2-Caecam1*4L)1Rsb T cell transfer
• thymocyte number is reduced to 1-3 x 106 cells compared to 200-300 x 106 cells in wild-type mice
• colonic lamina propria lymphocytes (LPL) produce less Ifng and IL-2 in recipients of Tg(CD2-Caecam1*4L)1Rsb T cells
• in anti-Ifng treated mice, upregulation of Nos2 production by macrophages is abolished after M. tuberculosis infection relative to untreated Rag2-null mice wherease YM-1 and L-arginase 1 expression are elevated 60- and 3000-fold compared to untreated mutants
• chemokines KC and MIP-2 are increased in NK cells in infected lungs of anti-Ifng treated mice
• incubation of Rag2-null splenocytes with mycobacteria (M. tuberculosis) induces high levels of interferon gamma; this induction is increased at higher multiplicities of infection (MOI)
• at 28 days p.i., lungs display a few small foci with limited mononuclear infiltration
• mice survive infection with M. tuberculosis for the period of observation (day 50), whereas Ifng-null animals all succumb rapidly to infection
• neutralization of Ifng in infected mice abolishes the resistance to infection displayed by untreated mice
• in lungs and spleens of M. tuberculosis-infected mice at 28 days post-infection (p.i.), bacterial loads are higher than in infected wild-type mice
• neutralization of Ifng in infected mice results in 0.5-1.0 log higher bacterial burdens in lungs and spleens than in untreated Rag2-null mice
• in a mouse model of colitis, recipients of Tg(CD2-Caecam1*4L)1Rsb splenic T cells display less severe wasting than recipients of wild-type splenic T cells`
• this is associated with less severe macro- and microscopic colitis

hematopoietic system
• thymocyte number is reduced to 1-3 x 106 cells compared to 200-300 x 106 cells in wild-type mice
• colonic lamina propria lymphocytes (LPL) produce less Ifng and IL-2 in recipients of Tg(CD2-Caecam1*4L)1Rsb T cells

respiratory system
• at 28 days p.i., lungs display a few small foci with limited mononuclear infiltration

• mice show no sign of lesion development for up to 12 to 14 weeks after infection; after 20 weeks, all lesions remain small
• mice reconstituted with 1x10 7 CD4+ T cells develop smaller lesions containing 100-fold less parasites than wild-type or mutants reconstituted with 1.5x10 7 CD4+ T cells

digestive/alimentary system
• when given 10-20 mg/kg indomethacin, mice develop small nonhemorrhagic lesions in the jejunum, similar to controls in severity
