Lupus-like autoimmune disease in Lyntm1Sor/Lyntm1Sor and Lyntm1.1Calo/Lyntm1.1Calo Top2aGt(PST14568)Mfgc/0 mice

mortality/aging
• average survival time of 8 months

immune system
• severe splenomegaly starting at 6 months of age
• spleens are 16- and 7.9-fold larger than those in controls and mice homozygous for Lyntm1Sor, respectively
• dramatic expansion of myeloid compartment in the spleen and lymph nodes
• myeloid proliferations occurs earlier than in mice homozygous for Lyntm1Sor
• increase in the numbers of CD11chi MHCII+ conventional DCs and CD11clo B220+ Ly6C+ plasmacytoid DCs in the spleen and lymph nodes over time
• increased numbers of monocytes/macrophages in the spleen and lymph nodes at 4 months of age
• in the spleen and lymph nodes at 4 months of age
• increase in the number of CD19lo/- CD138hi plasma cells in the spleen
• high numbers of CD44hi CD62Llo/- effector T cells and CD69+ T cells
• in secondary lymphoid organs
• in the spleen and lymph nodes at 4 months of age
• myeloid cells are hyperresponsive to LPS
• in secondary lymphoid organs
• increased levels of granulocyte and granulocyte macrophage colony stimulating factors at 6 months of age
• high levels of circulating B-cell activating factor
• increased levels of a number of chemokines at 6 months of age
• increase in lymph node size and cellularity as early as 4 months of age, mainly due to increased numbers of T cells myeloid cells and dendritic cells
• following exposure to Brefeldin A and LPS, splenic dendritic cells produce high levels of inflammatory cytokines
• CD11chi DCs are hyperresponsive to cytokine stimulation
• high levels of autoreactive antibodies in the serum
• by 8 months of age, 60-70% of mice display severe leukocyte infiltration in the lungs, liver, and skin
• enlarged glomeruli and increased leukocyte infiltration indicative of glomerulonephritis at 6 months of age
• abundant leukocyte infiltration in the interstitial tissue at 6 months of age

integument

renal/urinary system
• enlarged glomeruli and increased leukocyte infiltration indicative of glomerulonephritis at 6 months of age
