Murine postthymectomy autoimmune oophoritis develops in association with a persistent neonatal-like Th2 response

Abstract

Autoimmune oophoritis develops in some patients despite evidence of impaired cellular immunity. Here, using the murine postthymectomy model of autoimmune oophoritis, we investigate the hypothesis that neonatal thymectomy induces autoimmune oophoritis by disrupting the normal postnatal balance of T helper cell regulation. Stimulated CD4+ splenic lymphocytes from adult mice sham-operated as neonates produced the expected T helper type 1 (Th1) predominant response normally seen in adult mice (low levels of interleukin-4 and high levels of interferon gamma). In contrast, cells from adult mice thymectomized as neonates produced an inappropriate neonatal-like Th2-predominant response (high levels of interleukin-4 and low levels of interferon-gamma). Manipulations that restored the postnatal shift to an adult Th1-dominant pattern ameliorated the autoimmune oophoritis. Thus, neonatal thymectomy abrogates the postnatal shift to a Th1-dominant pattern, and the resulting persistent neonatal-like Th2-dominant response is tightly associated with the development of postthymectomy autoimmune oophoritis. These results (i) suggest that the postnatal shift to the normal adult Th1/Th2 balance is established by a thymus-dependent process and (ii) ...Continue Reading

Autoimmune Polyendocrinopathies

Autoimmune polyendocrinopathies, also called polyglandular autoimmune syndromes (PGASs), or polyendocrine autoimmune syndromes(PASs), are a heterogeneous group of rare diseases characterized by autoimmune activity against more than one endocrine organ, although non-endocrine organs can be affected. Discover the latest research on autoimmune polyendocrinopathies here.

Autoimmune Polyendocrine Syndromes

This feed focuses on a rare genetic condition called Autoimmune Polyendocrine Syndromes, which are characterized by autoantibodies against multiple endocrine organs. This can lead to Type I Diabetes.

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
