The value of animal models in predicting genetic susceptibility to complex diseases such as rheumatoid arthritis
For a long time, genetic studies of complex diseases were most successfully conducted in animal models. However, the field of genetics is now rapidly evolving, and human genetics has also started to produce strong candidate genes for complex diseases. This raises the question of how to continue gene-finding attempts in animals and how to use animal models to enhance our understanding of gene fu...
متن کاملAnimal models of rheumatoid arthritis.
Animal models of arthritis are used to study pathogenesis of disease and to evaluate potential anti-arthritic drugs for clinical use. Therefore morphological similarities to human disease and capacity of the model to predict efficacy in humans are important criteria in model selection. Animal models of rheumatoid arthritis (RA) with a proven track record of predictability for efficacy in humans...
متن کاملTh17 in Animal Models of Rheumatoid Arthritis
IL-17-secreting helper CD4 T cells (Th17 cells) constitute a newly identified subset of helper CD4 T cells that play a key role in the development of rheumatoid arthritis (RA) in its animal models. Recently, several models of spontaneous RA, which elucidate the mechanism of RA onset, have been discovered. These animal models shed new light on the role of Th17 in the development of autoimmune ar...
متن کاملAutoantibodies in normals – the value of predicting rheumatoid arthritis
Introduction The cause of rheumatoid arthritis (RA) remains elusive, however, a study demonstrating synovitis in clinically uninflamed joints [1] and several studies reporting the presence of characteristic autoantibodies (IgM rheumatoid factor [RF] and anti-cyclic citrullinated peptide [CCP] antibodies) prior to the appearance of disease manifestations [2–7] have provided evidence of a preclin...
متن کاملRheumatoid arthritis and systemic lupus erythematosus as immune complex diseases.
Rheumatoid factors are 9s IgM autoantibodies directed against the hinge regions of 7s IgG's that have been changed consequent to their encounter with a foreign antigen, such as those produced by oral bacteria. Occasionally self-aggregating 7s IgG's serve this function. When these complexes are taken up by phagocytes in the joint, they form the "RA cell," a cell analogous to the LE cell of Hargr...
