BACKGROUND
Type 1 diabetes is caused by a destruction of pancreatic beta cells due to autoimmunity. Autoantibody against glutamic acid decarboxylase (GAD) 65 expressed in pancreatic beta cells is widely used as a predictive marker for pancreatic destruction. In this study, we hypothesized that if
We have examined the frequency and distribution of neuron profiles immunoreactive for glutamic acid decarboxylase, a biosynthetic enzyme for the putative inhibitory neurotransmitter, gamma aminobutyric acid, in the lumbar spinal cord of colchicine-treated rats with unilateral inflammation of a
Anti-glutamic acid decarboxylase directed antibodies are a rare cause of autoimmune limbic encephalitis that is relatively resistant to immunotherapy. Here we report a 15-year-old boy with nonparaneoplastic, anti-glutamic acid decarboxylase limbic encephalitis presenting with subacute headache,
OBJECTIVE
To describe novel neurological manifestations associated with glutamic acid decarboxylase (GAD65) autoimmunity.
METHODS
This retrospective study (1987-2003) describes 62 patients Incidentally found to have a serum autoantibody that bound selectively to synapse-rich central nervous system
Glutamic acid decarboxylase (GAD) 65 is one of the major pancreatic antigens targeted by self-reactive T cells in type I diabetes mellitus. T cells specific for GAD65 are among the first to enter inflamed islets and may be important for the initiation of autoimmune diabetes. However, we previously
To evaluate the association of autoimmunity to glutamic acid decarboxylase (GAD) with insulin-dependent diabetes mellitus (IDDM) and IDDM-associated human leukocyte antigen (HLA) types, we studied a unique group of 47 patients with autoimmune polyendocrine syndrome type 1, a recessive disease not
Oral tolerance mediated by autoantigens has been applied successfully as a potential therapeutic strategy for preventing and treating autoimmune diseases. We previously showed cholera toxin B subunit (CTB) is an efficient mucosal carrier molecule for induction of systemic T cell tolerance to linked
CD4(+) T cell responses to glutamic acid decarboxylase (GAD65) spontaneously arise in nonobese diabetic (NOD) mice before the onset of insulin-dependent diabetes mellitus (IDDM) and may be critical to the pathogenic process. However, since both CD4(+) and CD8(+) T cells are involved in autoimmune
Nonobese diabetic (NOD) mice develop a T-cell dependent autoimmune form of diabetes, in which glutamic acid decarboxylase 65 (GAD65) is an important islet target antigen. Intramuscular DNA vaccination with a plasmid encoding native GAD65 (a cytosolic antigen) did not significantly alter the
Dendritic cells are the largest population of antigen presenting cells in the body. One of their main functions is to regulate the delicate balance between immunity and tolerance responsible for maintenance of immunological homeostasis. Disruption of this delicate balance often results in chronic
Background Asthma is a disease characterized by airway inflammation, remodelling and dysfunction. Airway inflammation contributes to remodelling, a term that is used to describe structural changes including goblet cell metaplasia (GCM), matrix deposition, and smooth muscle hyperplasia/hypertrophy.
At the clinical onset of insulin-dependent diabetes mellitus (type 1 diabetes), inflammation within the pancreatic islets of Langerhans causes insulitis. CD4+ or Th-lymphocytes will be activated after stimulation resulting in interferon-gamma (IFN-gamma) production by Th1-like lymphocytes and/or
NOD mice constitute a model for studying the prevention of human autoimmune type 1 diabetes. Glutamic acid decarboxylase (GAD) could be a key antigen involved in this disease, and GAD65 peptide 524-543 has been implicated in early T cell response in young NOD mice. We performed two i.p. injections
DNA vaccination encoding beta cell autoantigens has been shown very recently to prevent type I diabetes in non-obese diabetic (NOD) mice. However, DNA vaccination encoding microbial or reporter antigens is known to induce specific long-lasting CD4 Th1 and strong cytolytic CD8 T cell responses. As
Bickerstaff brainstem encephalitis (BBE) is a rare inflammatory demyelinating condition, which is similar to Miller-Fisher syndrome (MFS). Ophthalmoplegia and ataxia are common to these syndromes but unlike MFS, BBE is also characterised by central nervous system involvement, most commonly in the
