CD4(+) T (helper) cells migrate in huge numbers through lymphoid organs. However, little is known about traffic routes and kinetics of CD4(+) T-cell subsets within different organ compartments. Such information is important because there are indications that CD4(+) T cells may influence the function of microenvironments depending on their developmental(More)
The protozoan parasite Leishmania spp. causes clinical pictures ranging in severity from spontaneously healing skin ulcers to systemic disease. The immune response associated with healing involves the differentiation of IFNγ-producing Th1 cells, whereas the non-healing phenotype is associated with IL4-producing Th2 cells. The widespread assumption has been(More)
The differentiation of CD4 T cells into Th1 and Th2 cells in vivo is difficult to analyze since it is influenced by many factors such as genetic background of the mice, nature of antigen, and adjuvant. In this study, we used a well-established model, which allows inducing Th1 or Th2 cells simply by low (LD, 10(5)) or high dose (HD, 10(9)) injection of sheep(More)
Microfibrillar-associated protein 4 (MFAP4) is an extracellular protein belonging to the fibrinogen-related protein superfamily and is recognized as an integrin ligand with suggested functions in pulmonary and vascular tissue homeostasis. MFAP4 expression in the spleen is increased during infections; however, the significance of MFAP4 for the function of(More)
Autoantibodies are believed to be maintained by either the continuous generation of short-lived plasma cells in secondary lymphoid tissues or by long-lived plasma cells localized in bone marrow and spleen. Here, we show in a mouse model for the autoimmune blistering skin disease epidermolysis bullosa acquisita (EBA) that chronic autoantibody production can(More)
BACKGROUND Next generation sequencing (NGS) technologies enable studies and analyses of the diversity of both T and B cell receptors (TCR and BCR) in human and animal systems to elucidate immune functions in health and disease. Over the last few years, several algorithms and tools have been developed to support respective analyses of raw sequencing data of(More)
T cells are key players in autoimmune diseases by supporting the production of autoantibodies. However, their contribution to the effector phase of antibody-mediated autoimmune dermatoses, i.e., tissue injury and inflammation of the skin, has not been investigated. In this paper, we demonstrate that T cells amplify the development of autoantibody-induced(More)
