Causes of kidney pain
The finding that the structure of a Class II molecule can predispose a patient to the development of RA, therefore, strongly supports a role for CD4+ T cells in the pathogenesis of RA - at least, in the initiation of disease. causes of kidney pain Quotes on pain. Indeed, CD4+ cells are the predominant T cell subtype found in rheumatoid synovium. The identity of the putative peptide presented by DR4 remains unknown, however. Several lines of evidence have suggested participation of viral or bacterial antigens. causes of kidney pain Chest-wall-pain. For example, injection of rats with peptidoglycan constituents of streptococcal cell walls induces a chronic erosive inflammatory arthritis in these animals, and the antigens can be identified within the joint (even though injected subcutaneously, not intraarticularly) (slide). Blood-borne foreign antigens could thus become trapped in the joint where they stimulate an immune response. Alternatively, foreign antigens might mimic host antigens. causes of kidney pain Psoriatic arthritis & kineret. An immune response to the foreign antigen would break tolerance to the self-antigen that it mimics, leading to autoreactivity against self. In support of this concept, the 110-kD late major capsid protein of Epstein-Barr virus and the Escherichia coli dnaJ 40-kD heat-shock protein have the sequence of E Q K R A A, which includes the shared epitope discussed above (slide). In addition, antibodies directed against immunoglobulins (rheumatoid factor) and against type II collagen support the concept of autoreactivity against self, although these phenomena may be a result of disease rather than a cause of it. Insofar as no disease-inducing antigen has yet been clearly identified, an alternative approach to the study of the disease consists of analyzing the molecular diversity of the T cell population in the joint.
