Spleen cells from non-obese diabetic mice were found to generate low interleukin 2 production and cell proliferation in response to concanavalin A. However, some of non-obese diabetic mice maintained in the same environment preserved their responsiveness to this T cell mitogen. Non-obese diabetic
In contrast to systemic autoimmunity, spontaneous autoimmune thyroiditis of Obese strain (OS) chickens is associated with a marked T cell hyperreactivity in vitro, i.e. an increased proliferation and interleukin 2 (IL 2) secretion in response to Concanavalin A (ConA). In the present study we report
Lymphocytes were isolated from the infiltrated thyroid glands of 2- to 5-wk-old Obese strain (OS) chickens with spontaneous autoimmune thyroiditis (SAT). Immunofluorescence analysis performed by using a panel of monoclonal and polyclonal antibodies revealed that 60% of thyroid infiltrating
The objective of this study was to investigate food restriction-related changes in several indices of immune competence in young (11 wk old) and adult (33 wk old) female lean (+/?) and obese (ob/ob) C57BL/6J mice. Body weight accumulation, tail length accretion and organ weights were more severely
Type I diabetes mellitus is a chronic disorder that results from autoimmune destruction of the insulin-producing pancreatic beta cell. The non-obese diabetic mouse is a model of the human autoimmune disease Type I diabetes [1-3]. We have previously shown that ingested type 1 interferon inhibits
OBJECTIVE
Interferon regulatory factor-1 (IRF-1) is a critical regulator of interferon-gamma(IFNgamma)-mediated immune responses. To determine whether IRF-1 is involved in the pathogenesis of thyroiditis in animal models, we evaluated the incidence of iodide-induced lymphocytic thyroiditis (LT) in
The effect of thyroxine (T4) and/or recombinant chicken growth hormone (rcGH) supplementation on immune function and on immune cell maturation was examined in Obese strain chickens. Day-old Obese strain chicks received the control treatments or were treated with either T4 (supplemented in the diet),
Non-obese diabetic (NOD) mice injected with CD3 antibody as newborns have a reduced incidence of diabetes, raising the possibility that the neonatal injection caused a long-lasting change in circulating T cells. The present study shows that NOD and BALB/c mice injected with soluble CD3 antibody in
Since the modulation of the immune system at birth may influence the course of insulin-dependent (type 1) diabetes, we investigated whether neonatal injections of cyclosporin (CsA) to newborn non-obese diabetic (NOD) mice influence diabetes during later life. Two groups of 90 mice (45 female, 45
The metastasis of B16 melanoma cells differed significantly in obese (ob/ob) and lean (+/?) female mice of strain C57BL/6J. When the mice were inoculated subcutaneously with melanoma cells at 10 to 11 months of age, the primary tumor grew more slowly in obese than in lean littermates and the
The aim of this study was to investigate whether lymphocyte vaccination can prevent diabetes occurring in the non-obese diabetic (NOD) mouse, an animal model of human insulin-dependent diabetes mellitus (IDDM). The lymphocyte vaccine was composed of lymphocytes isolated from the spleens of diabetic
OBJECTIVE
We previously reported elevated serum levels of the cytokines interleukin-6 (IL-6) and transforming growth factor-beta (TGF-beta) in patients with anorexia nervosa (AN). We investigated the cellular production of these two cytokines and of interferon-gamma (IFN-gamma), interleukin-1alpha
BACKGROUND
Interleukin-22 (IL-22), a cytokine with important functions in anti-microbial defense and tissue repair, has been recently suggested to have beneficial effects in obesity and metabolic syndrome in some but not in other studies. Here, we re-examined the effects of IL-22 on obesity, insulin
Interferon regulatory factor-1 (IRF-1) is a transcription factor involved in interferon-mediated immune reaction, CD8+ T cell differentiation and development of T helper 1 immune reaction. We have recently demonstrated that IRF-1 is pivotal in iodine-induced lymphocytic thyroiditis (LT) in non-obese
As the study of type 1 diabetes moves towards preventive therapy, the role of adjuvants needs to be addressed. Incomplete Freund's adjuvant (IFA) is thought of as "immunologically inert" as, unlike complete FA (CFA), it has no components designed to provoke an immune response. We investigated the
