An Immunoglobulin Light Chain
Identification of the immunogens responsible for the production of pathogenic autoantibodies is a major problem in the field of autoimmunity. In the principal diseases that are thought to involve autoimmunization, rheumatoid arthritis, type I diabetes, and multiple sclerosis are examples, the instigating stimulus is unknown. Another example of the gap in our knowledge of disease-causing immunog...
متن کاملDual T cell receptor alpha chain T cells in autoimmunity
Allelic exclusion at the T cell receptor alpha locus TCR-alpha is incomplete, as demonstrated by the presence of a number of T lymphocyte clones carrying two expressed alpha chain products. Such dual alpha chain T cells have been proposed to play a role in autoimmunity, for example, because of a second TCR-alpha beta pair having bypassed negative selection by virtue of low expression. We examin...
متن کاملAtypical immunoglobulin light chain amyloidosis
BACKGROUND Primary immunoglobulin light chain amyloidosis (AL amyloidosis) is a plasma cell disorder which mainly affects heart, kidneys, liver, and peripheral nervous system. Cases of atypical AL amyloidosis presented as spontaneous vertebral compression fractures have been rarely reported, and data about the management and clinical outcomes of the patients are scarce. METHODS Herein, we pre...
متن کاملFunctional Immunoglobulin Light Chain Genes
Rearrangement of Ig genes proceeds during B cell differentiation in an orderly fashion. First the heavy (H) chain gene is rearranged in pre-B cells . These cells can express cytoplasmic A chain but no light (L) chain (1). The K light chain genes rear range next and if they fail to produce a functional gene on either chromosome the X light chain genes are rearranged (2) . It is generally believe...
متن کاملHematopathology / SURFACE IMMUNOGLOBULIN LIGHT CHAIN–NEGATIVE PERIPHERAL B-CELL LYMPHOMA Lack of Surface Immunoglobulin Light Chain Expression by Flow Cytometric Immunophenotyping Can Help Diagnose Peripheral B-Cell Lymphoma
We determined the prevalence and significance of finding B cells without surface immunoglobulin (SIg) light chain expression. The flow cytometry database at Johns Hopkins Medical Institutions was searched for cases in which immunoglobulin light chain staining was performed to rule out a B-cell malignant neoplasm between January 1994 and February 2000. We excluded plasma cell dyscrasias, precurs...
