Although no single animal model of systemic sclerosis (SSc) faithfully reproduces all features of the human disease, certain animal models that display some of the features of SSc are potentially useful as they may be helpful in gaining a better understanding of the pathogenesis of SSc as well as d ...

Exerimental autoimmune encephalomyelitis (EAE) is an inflammatory demyleinating disease of the central nervous system that is induced in laboratory animals by the generation of an immune response against myelin epitopes. It has been used as a prototype of Th1-driven, organ-specif ...

This chapter describes the major principals, methods, and immunization protocols for the induction of a systemic autoimmune arthritis in genetically susceptible murine strains. The model is called proteoglycan-induced arthritis (PGIA) because the antigenic/arthritoge ...

Collagen-induced arthritis (CIA) is an experimental autoimmune disease that can be elicited in susceptible strains of rodents (rat and mouse) and nonhuman primates by immunization with type II collagen (CII), the major constituent protein of articular cartilage. Following immuni ...

CD4+ T-cell DNA hypomethylation may contribute to the development of drug-induced and idiopathic human lupus. Inhibiting DNA methylation in mature CD4+ T cells causes autoreactivity specific to the major histocompatibility complex in vitro. The lupus-inducing drugs hydralazi ...

The injection of spleen cells from bm12 mice into C57BL/6 recipients induces a chronic graft-vs-host reaction characterized by systemic autoimmunity, including anti-double-stranded DNA (anti-dsDNA) autoantibodies and immune complex-type proliferative glomerulone ...

Murine models of systemic lupus erythematosus provide fertile research systems for the pathogenesis and therapy of systemic autoimmune disease. Their phenotypes span the broad range of clinical manifestations of human lupus and consist of both spontaneous and experimentally i ...

The ability to generate, maintain, and use cloned lines of T cells reactive for self-antigens has opened up a new avenue of investigation for researchers. These T-cell clones allow the rapid induction of tissue-specific autoimmunity with the intent of dissecting the contribution of the diff ...

Animal models have contributed enormously to study in the field of type 1 diabetes. Perhaps the most intensively studied model is the nonobese diabetic (NOD) mouse, which develops an autoimmune-mediated spontaneous diabetes associated with the development of insulin autoantibod ...

This chapter describes four murine models of autoimmune diseases: two related to autoimmune myocarditis and two related to autoimmune thyroiditis. The first model, Coxsackie virus B3 (CB3)-induced myocarditis, results in the development of acute myocarditis in susceptible as well ...

Transaldolase is a target of autoimmunity mediated by T cells and antibody (Ab) in patients with multiple sclerosis. Functional T-cell assays, T- and B-cell epitope mapping, and detection of transaldolase-specific antibodies in patients with multiple sclerosis are described. Reco ...

Systemic autoimmune diseases are characterized by extensive alterations in immune system function, with cytokines and autoantibodies contributing to impaired immunoregulation and tissue damage. Characterization of the expression and function of cytokines is importa ...

Apoptotic cells are sources of tolerogenic material during tissue homeostasis; abnormalities in apoptosis or in the clearance of apoptotic material generate a novel source of antigens against which an autoimmune response may be initiated. In our laboratory, we study the biochemist ...

Systemic lupus erythematosus (SLE) is characterized by abnormal activation and cell death signaling within the immune system. Activation, proliferation, or death of cells of the immune system are dependent on controlled reactive oxygen intermediate (ROI) production and ATP synt ...

Abnormal T-cell effector functions in systemic lupus erythematosus (SLE) are present and may be associated with disease immunopathogenesis. Our work has led to the characterization of a signaling defect, involving protein kinase A (PKA), leading to abnormal T-cell effector functio ...

A growing number of studies have revealed that the expression of many genes is abnormal in T lymphocytes of patients with systemic lupus erythematosus (SLE). Although aberrant expression of signaling molecules may arise intrinsically or in response to the environment, these abnormal ...

Abnormal expression of key signaling molecules and defective functions of T lymphocytes play a significant role in the pathogenesis of systemic lupus erythematosus (SLE). T-cell receptor (TCR)/CD3-mediated stimulation of SLE T cells shows increased protein tyrosine phosphory ...

Systemic lupus erythematosus (SLE) is a prototype systemic, autoimmune inflammatory disease that can involve virtually any organ or tissue type. The disease has a strong familial tendency but, like most human illness, has a complex pattern of inheritance that is consistent with multiple ...

The immune system specifically recognizes and eliminates foreign antigens and thus protects the integrity of the host. During maturation of the immune system, tolerance mechanisms develop that prevent or inhibit potentially harmful reactivities to self-antigens. Autoreact ...

The modification of chromosomal loci by homologous recombination is commonly referred to as gene targeting, the importance of which needs no emphasis. Gene targeting has been widely used in mice to make a variety of mutations in many different loci, including those of the complement compone ...
