Type B insulin resistance (IR) is a rare autoimmune disease characterized by the presence of insulin receptor autoantibodies, resulting in a marked IR inducing hyperglycemia.
(b) Differences in modulation of the insulin receptor signaling cascade are found with TNF-alpha and high glucose: Hyperglycemia-induced insulin receptor inhibition blocks both insulin receptor-dependent tyrosine phosphorylation and dephosphorylation of insulin receptor substrate proteins.
Insulin receptor and insulin receptor substrate-1 (IRS-1) messenger RNA, known stimulate to membrane translocation of Gluts, were both decreased by the HG condition but not by the NG condition.
