Antinuclear antibodies defining autoimmunity pathways

Antinuclear antibodies defining autoimmunity pathways

Immunofluorescent imaging has been a powerful technique in helping to identify intracellular nuclear and cytoplasmic molecules which are target antigens of autoantibodies in systemic autoimmune disorders. Patterns of staining can be correlated with molecules engaged in specific cellular functions and distributed in distinct cellular domains. Different autoimmune disorders have different profile...

High Prevalence of Antinuclear Antibodies in Children with Thyroid Autoimmunity

BACKGROUND Antinuclear antibodies (ANA) are a hallmark of many autoimmune diseases and can be detected many years before disease onset. Autoimmune thyroid diseases (AITD) are frequently associated with other organ- and non-organ-specific autoimmune disorders. Objectives. To assess the prevalence of ANA in pediatric patients with AITD and their clinical correlations. METHODS Ninety-three conse...

Antinuclear Antibodies

knowledge of gene regulation, particularly in neoplastic cells, this deficit is striking. With our current understanding of chromosomal translocations, point mutations, and gene amplification in tumor cells, it is surprising to read that there is ". . . no difference between cancer and normal DNA . . ." (p. 130). The author spends a fair amount of time discussing possible mechanisms for the car...

Somatic hypermutation as a generator of antinuclear antibodies in a murine model of systemic autoimmunity

Systemic lupus erythematosus (SLE) is characterized by high-avidity IgG antinuclear antibodies (ANAs) that are almost certainly products of T cell-dependent immune responses. Whether critical amino acids in the third complementarity-determining region (CDR3) of the ANA originate from V(D)J recombination or somatic hypermutation (SHM) is not known. We studied a mouse model of SLE in which all so...
