immune system
• some loss of B and T cell area segregation, however less than seen in homozygous Tnftm1Jods mice
• the MOMA-1+ marginal zone metallophilic macrophages did not form a completely continuous cell layer
• follicular dendritic cell networks were undetectable in unimmunized homozygous mutant mice
• size and frequency of the formation CR1+ follicular dendritic networks upon immunization was substantially less than in wild-type
• absent primary B cell follicles
• frequency of the formation of PNA+ germinal centers upon immunization was substantially less than in wild-type
• size of PNA+ germinal centers upon immunization was substantially less than in wild-type
• imperfect primary B cell follicles, however separation of T and B cell regions was fairly normal
• reduced severity of experimental autoimmune encephalomyelitis (EAE) under suboptimal immunization conditions relative to wild-type, with less inflammation in the spinal cord and the majority of homozygous mutant mice recovering rapidly
• resistant to endotoxic shock induced by low doses of LPS, however at high doses, started to show signs of shock and 2/5 mice succumbed to shock, however with a delayed time of death compared to wild-type

• mutants control parasite replication as effectively as infected wild-type C57Bl/6 60 days following infection with L.major
• neutrophil numbers are similar in uninfected or infected (during first days of infection) wild-type controls and Tnf-null mice; levels after 7 days are similar to infected controls
• lymph node cells secrete similar levels of IFN-gamma to cells from infected wild-type; upon L. major re-stimulation, similar levels of Il-4 are released
• number of parasitized neutrophils in lesion is similar to infected controls at 4 hours after i.p. injection of L. major; percentage of proliferating parasites released from neutrophils is similar to infected controls
• levels of IgG2a in sera are lower than in infected wild-type controls
• number of IFN-gamma secreting CD4+ T cells is slightly but significantly increased in draining lymph nodes compared to infected wild-type C57BL/6
• initially, were able to contain M. tuberculosis growth to a similar extent as wild-type, however were unable to control infection long term (after about 12 weeks), showed more diffuse lesions and increased neurtrophil infiltrate than in wild-type and had a mean time of death at 170 days
