• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

respiratory system

respiratory system inflammation ( J:61023 )

• after antigen exposure of sensitized mice, airway hyperactivity was little affected by antigen exposure

• less affect on Il-4, Il-5, and Il-13

• less cell infiltration of lungs

• fewer mucus containing cells

immune system

increased CD4-positive, alpha-beta T cell number ( J:243958 )

• MHV-infected mice exhibit higher frequency and numbers of virus-specific CD4 T cells in the brain

• however, virus-specific CD8 T cell numbers in MHV-infected mice are similar to wild-type

increased regulatory T cell number ( J:243958 )

• MHV-infected mice exhibit higher numbers of T regulatory cells

• however, MHV-infected mice do not show differences in the frequency and numbers of macrophages, microglia, or neutrophils in the brain

abnormal macrophage activation involved in immune response ( J:243958 )

• marker analysis indicates that MHV-infected mice exhibit less activated macrophages

decreased microglial cell activation ( J:243958 )

• marker analysis indicates that MHV-infected mice exhibit less activated microglia

increased interleukin-1 beta secretion ( J:243958 )

• levels of secreted IL-1beta are greater in bone marrow macrophages at 12 and 24 hours post MHV A59 infection

brain inflammation ( J:243958 )

• mice infected with MHV show more extensive perivascular inflammation in the brain at 6 and 10 days post infection (dpi) than wild-type mice

respiratory system inflammation ( J:61023 )

• after antigen exposure of sensitized mice, airway hyperactivity was little affected by antigen exposure

• less affect on Il-4, Il-5, and Il-13

• less cell infiltration of lungs

• fewer mucus containing cells

increased susceptibility to Coronaviridae infection ( J:243958 )

• mice intracranially infected with the JHM strain of mouse hepatitis virus (MHV) exhibit weight loss, increased morbidity, and increased viral titers in the brain

increased susceptibility to Coronaviridae infection induced morbidity/mortality ( J:243958 )

• mice intracranially infected with the JHM strain of mouse hepatitis virus (MHV) exhibit increased mortality from 10 % in controls to about 80%

• mice intracranially infected with the A59 strain of MHV show increased mortality, with 0% survival compared to 70% in wild-type mice

• treatment with an IL-1 receptor antagonist anakinra improves the survival of MHV-infected mice from 10% to about 70%

mortality/aging

increased susceptibility to Coronaviridae infection induced morbidity/mortality ( J:243958 )

• mice intracranially infected with the JHM strain of mouse hepatitis virus (MHV) exhibit increased mortality from 10 % in controls to about 80%

brain inflammation ( J:243958 )

• mice infected with MHV show more extensive perivascular inflammation in the brain at 6 and 10 days post infection (dpi) than wild-type mice

spongiform encephalopathy ( J:243958 )

• mice infected with MHV show large, multifocal, spongiform lesions in the brainstems by 10 dpi compared to only mild lesions with monocytic infiltration in wild-type mice
