Gw mau tau Cellular dari Kerintangan insulin. Jelasin dalam bahasa melayu

At the cellular level, excessive circulating insulin appears to be a contributor to insulin resistance via down-regulation of insulin receptors. This occurs due to prolonged and repeated elevations of circulating insulin. Since the usual instances of Type 2 insulin resistance are distinct from pathological over production of insulin, this does not seem to be the typical cause of the insulin resistance leading to Type 2 diabetes mellitus, the largest clinical issue connected with insulin resistance. The presence of insulin resistance typically precedes the diagnosis of Types 2 diabetes mellitus, however, and as elevated blood glucose levels are the primary stimulus for insulin secretion and production, habitually excessive carbohydrate intake is a likely contributor. Additionally, some Type 2 cases require so much external insulin that this down-regulation contributes to total insulin resistance.

Inflammation also seems to be implicated in causing insulin resistance. Mice without JNK1-signaling do not develop insulin resistance under dietary conditions that normally produce it.

Vitamin D deficiency is also associated with insulin resistance.

Some research has shed light on a complex interaction between elevated free fatty acids and inflammatory cytokines seen in obesity activating Protein Kinase C isoform theta. PKC Theta inhibits Insulin Receptor Substrate (IRS) activation and hence prevents glucose up-take in response to insulin.
