Phenotypes Associated with This Genotype

Genotype
MGI:3709555

• Allelic Composition: H2^q/?; Ncf1^m1J/Ncf1^m1J
• Genetic Background: B6.Cg-Ncf1^m1J H2^q

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

Ncf1^m1J/ Ncf1^m1J mice carrying the H2^q haplotype develop enhanced collagen II autoimmunity and chronic collagen II induced arthritis

immune system

increased susceptibility to type IV hypersensitivity reaction ( J:92437 )

• the delayed-type hypersensitivity response against collagen II, not but OVA, is elevated compared to wild-type

decreased susceptibility to experimental autoimmune encephalomyelitis ( J:92437 )

• MOG(79-96) peptide-induced EAE is milder in mutants than in wild-type

increased susceptibility to experimental autoimmune encephalomyelitis ( J:92437 )

• MOG protein-induced EAE is more severe in mutants than in wild-type

increased susceptibility to induced arthritis ( J:92437 )

• mutants exhibit increased susceptibility to collagen II induced arthritis, developing more severe arthritis and earlier onset than wild-type

• levels of antibodies directed against the injected collagen II antigen are higher, with a predominant increase in IgG

rheumatoid arthritis ( J:92437 )

• many females develop severe arthritis during the first days after partus; arthritis is as severe and chronic as the collagen II induced arthritis

• females exhibit massive destruction of bone and cartilage in the ankle joint and have an elevated amount of antibodies against collagen II
