The lymphatic vasculature is critical for immunity and interstitial fluid homeostasis, playing important roles in diseases such as lymphedema and metastatic cancer. Animal models have been generated to explore the role of lymphatics and lymphangiogenic growth factors in such diseases, and to study lymphatic development. However, analysis of lymphatic(More)
Systemic lupus erythematosus (SLE, lupus) is a highly complex and heterogeneous autoimmune disease that most often afflicts women in their child-bearing years. It is characterized by circulating self-reactive antibodies that deposit in tissues, including skin, kidneys, and brain, and the ensuing inflammatory response can lead to irreparable tissue damage.(More)
Transforming growth factor-β (TGF-β) signalling controls many aspects of cell behaviour and is implicated as a key regulator in tumour formation and progression. However, evaluating levels of active TGF-β in culture medium or patient plasma and gaining definitive information regarding the activity of downstream substrates such as Sma- and Mad-related(More)
Atopy and autoimmunity are usually considered opposed immunological manifestations. Lyn(-/-) mice develop lupus-like autoimmune disease yet have coexistent intrinsic allergic traits and are prone to severe, persistent asthma induced exogenously. Recently it has been proposed that the Th2 environment and IgE auto-Abs promotes autoimmune disease in Lyn(-/-)(More)
Lyn-deficient mice develop Ab-mediated autoimmune disease resembling systemic lupus erythematosus where hyperactive B cells are major contributors to pathology. In this study, we show that an inflammatory environment is established in Lyn(-/-) mice that perturbs several immune cell compartments and drives autoimmune disease. Lyn(-/-) leukocytes, notably B(More)
Lyn-deficient (Lyn(-/-)) mice develop an age-dependent autoimmune disease similar to systemic lupus erythematosus, characterized by the production of IgG anti-nuclear Ab. To determine the extent to which this autoimmune phenotype is driven by T cell costimulation, we generated Lyn(-/-) mice expressing a soluble form of the T cell inhibitory molecule, CTLA4(More)
OBJECTIVE Systemic lupus erythematosus (SLE) is a heterogeneous autoimmune disease that is characterized by the production of antinuclear antibodies (ANAs) and leads to immune complex deposition in the kidneys and nephritis. Lyn tyrosine kinase is a regulator of antibody-mediated autoimmune disease, as evidenced by studies in gene-targeted mice and as(More)
Systemic lupus erythematosus (SLE) is a heterogeneous autoimmune disease characterized by the production of autoantibodies against nuclear components. Lyn-deficient mice are an excellent animal model of SLE manifesting clinical, pathological and biochemical features seen in the human disease. They develop autoreactive antibodies, glomerulonephritis and show(More)
Ab-mediated autoimmune disease is multifaceted and may involve many susceptibility loci. The majority of autoimmune patients are thought to have polymorphisms in a number of genes that interact in different combinations to contribute to disease pathogenesis. Studies in mice and humans have implicated the Lyn protein tyrosine kinase as a regulator of(More)
SHIP-1 has an important role in controlling immune cell function through its ability to downmodulate PI3K signaling pathways that regulate cell survival and responses to stimulation. Mice deficient in SHIP-1 display several chronic inflammatory phenotypes including antibody-mediated autoimmune disease, Crohn's disease-like ileitis and a lung disease(More)
