Reduced diaphragm and cardiac fibrosis in Dmd^mdx/Y Spp1^tm1Blh/Spp1^tm1Blh and Dmd^mdx/Dmd^mdx Spp1^tm1Blh/Spp1^tm1Blh mice compared to Dmd^mdx/Dmd^mdx mice

immune system

decreased granulocyte number ( J:150572 )

• muscles contain fewer granulocytes than in Dmd^mdx homozygotes

decreased neutrophil cell number ( J:150572 )

• muscles contain fewer neutrophils than in Dmd^mdx homozygotes

decreased T cell number ( J:150572 )

• muscles contain fewer CD3+/Vbeta8.1/8.2+, and NKT-like cells than in Dmd^mdx homozygotes

increased T cell number ( J:150572 )

• muscles contain more CD3+ T cells than in Dmd^mdx homozygotes

increased regulatory T cell number ( J:150572 )

• muscles contain more CD3+CD4+ regulatory T cells than in Dmd^mdx homozygotes

muscle

abnormal muscle physiology ( J:150572 )

• mice exhibit improved muscle regeneration and reduced muscle inflammation and fibrosis in the diaphragm and heart compared with Dmd^mdx homozygotes

behavior/neurological

abnormal physical strength ( J:150572 )

• at 4 and 8 weeks, mice exhibit increased strength on a wire and grip test compared with Dmd^mdx homozygotes

hematopoietic system

decreased granulocyte number ( J:150572 )

• muscles contain fewer granulocytes than in Dmd^mdx homozygotes
