Where are RAGE receptors located?
The RAGE gene lies within the major histocompatibility complex (MHC class III region) on chromosome 6 and comprises 11 exons interlaced by 10 introns. Total length of the gene is about 1400 base pairs (bp) including the promoter region, which partly overlaps with the PBX2 gene.
How do advanced glycation end products form?
Advanced glycation end products (AGEs) are harmful compounds that are formed when protein or fat combine with sugar in the bloodstream. This process is called glycation ( 2 ). AGEs can also form in foods.
What type of receptor is RAGE?
Receptor for advanced glycation endproducts (RAGE) is a multi-ligand receptor that is able to bind several different ligands, including advanced glycation endproducts, high-mobility group protein (B)1 (HMGB1), S-100 calcium-binding protein, amyloid-β-protein, Mac-1, and phosphatidylserine.
What do RAGE receptors do?
RAGE is a multiligand receptor that propagates cellular dysfunction in several inflammatory disorders, in tumors and in diabetes. RAGE is expressed at low levels in normal tissues, but becomes upregulated at sites where its ligands accumulate.
What is receptor for advanced glycation endproducts?
The receptor for advanced glycation end products (RAGE) is a member of the immunoglobulin superfamily of cell surface molecules. The receptor is membrane bound and is also known as full length (fl)RAGE or membrane RAGE (mRAGE).
Is RAGE a scavenger receptor?
In addition, there are proteins exhibiting scavenger receptor activity that have been named based on other criteria and have not been included in a general scavenger receptor nomenclature. Some examples include RAGE, LRP1, LRP2, ASGP, CD163, SR-PSOX, and CXCL16.
What are examples of advanced glycation end products?
Compounds that have been found to inhibit AGE formation in the laboratory include Vitamin C, Agmatine, benfotiamine, pyridoxamine, alpha-lipoic acid, taurine, pimagedine, aspirin, carnosine, metformin, pioglitazone, and pentoxifylline.
Is HbA1c an advanced glycation end product?
The mechanism of early product formation has been well described, with HbA1c as the best-studied example. The finding that advanced glycation endproducts are also formed on haemoglobin suggests that HbA1c is a precursor for Hb-AGE formation.
What is FPS ZM1?
FPS-ZM1 is a high-affinity RAGE-specific blocker that inhibits amyloid-β binding to RAGE, neurological damage and inflammation in the APP(sw/0) transgenic mouse model of AD. FPS-ZM1 is not toxic to mice and can easily cross the blood-brain barrier.
Is Rage still a therapeutic target for Alzheimer’s disease?
RAGE-amyloid-β toxin interaction at the BBB leads to oxidative stress, inflammatory responses and reduced cerebral blood flow. Thus, regulating RAGE activity at the BBB and/or within brain could be beneficial to AD patients.
What are scavenger receptors examples?
Scavenger receptors are a diverse group of receptors that include CD36, CD68, SR class A, and SR class B. The receptors mediate the uptake of oxidized lipoproteins into cells. Scavenger receptors also mediate the uptake of microbes and contribute to the response of macrophages to mycobacteria.
