Systemic lupus erythematosus is characterized by B cell production of pathogenic autoantibodies dependent upon cooperation from CD4+ Th cells. The interaction between CD40 on B cells and CD40 ligand (CD40L) on Th cells is necessary for normal thymus-dependent Ab production. An anti-murine CD40L mAb blocks binding of CD40L to CD40 and prevents primary and(More)
Adequate inflammatory response predominated by macrophage infiltration is essential to acute skeletal muscle injury repair. The majority of intramuscular macrophages express the chemokine receptor CX3CR1. We studied the role of CX3CR1 in regulating intramuscular macrophage number and function in acute injury repair by using a loss-of-function approach.(More)
Genetic ablation or pharmacologic inhibition of CC chemokine receptor type 2 (CCR2) reduced macrophage (MP) infiltration and improved muscle pathology and function in mdx diaphragm muscle at early stages. We addressed whether CCR2 deficiency resulted in sustained improvement of mdx5cv-Ccr2-/- diaphragm. Compared to mdx5cv controls, CCR2 deficiency in(More)
We identified and characterized the function of CD45+/collagen I+ fibrocytes in acutely injured skeletal muscle of wild-type (WT) and Ccr2-/- mice, and in quadriceps and diaphragm muscles of mdx5cv mice, a mouse model for Duchenne muscular dystrophy. Fibrocytes were not detected in peripheral blood of WT mice after acute muscle injury or mdx5cv mice.(More)
