NAA Services for Anti-GluR3 Antibody

It is well known that natural autoantibodies (NAAs) can be valuable markers of disease activity and severity, an effective aid for disease classification and a guide for therapy. Since anti-glutamate receptor 3 (GluR3) autoantibodies are highly specific for epilepsy, based on years of extensive experience in disease diagnosis and NAA research, Creative Biolabs now offers a full range of high-quality antibody services against GluR3 marker for epilepsy research.

Background of Anti-GluR3 Antibody

Glutamate receptors (GluR) are the predominant excitatory neurotransmitter receptors in the mammalian brain and are activated in a variety of normal neurophysiologic processes. NAAs to the "B" peptide (372-395 aa) of GluR3 are found in serum and cerebrospinal fluid (CSF) of some patients with different types of epilepsy. Anti-GluR3B antibodies are produced primarily in the periphery due to specific/non-specific "irritation" of the immune system. Once they reach the brain via a leaky blood-brain barrier (BBB) they may cause neuronal/glial damage and facilitate the outburst of epilepsy and additional neurological abnormalities. Anti-GluR3 antibodies are “active” and potentially pathogenic molecules since they display a glutamate-like activity and thus induce glutamate receptor-mediated ion currents.

The Role of Anti-GluR3 Antibody in Epilepsy

Epilepsy is a major health problem, affecting almost 1-2% of the world population. Both the GluR-activating and the neuronal-killing potential of anti-GluR3 antibody suggest that they may contribute to epilepsy. Since such anti-GluR3B antibodies can activate and/or kill neurons in vitro and in vivo, they may contribute to epilepsy. Yet, more recent data clearly show that anti-GluR3 antibodies are neither specific nor restricted to Rasmussen’ s encephalitis (RE), as they are found in some patients with other types of epilepsy. Numerous cases proved that the presence of anti-GluR3 antibodies was highly specific for epilepsy compared to healthy controls.
