Anti-MAG Neuropathy

Anti-MAG neuropathy is peripheral neuropathy caused by the immune system attacking specific cells that maintain nervous system health. With our company's profound expertise in Anti-MAG neuropathy research, we are well-equipped to offer tailored solutions and comprehensive support to facilitate your research process from Anti-MAG neuropathy therapy development to therapy commercialization.

Overview of Anti-MAG Neuropathy

Anti-MAG neuropathy is an uncommon peripheral neuropathy characterized by the presence of antibodies against myelin-associated glycoprotein (MAG), a crucial component of the peripheral nervous system. Individuals with anti-MAG neuropathy experience distal sensory loss, tingling sensations, tremors, and poor balance, which can lead to difficulties in walking. As the disease progresses, muscle weakness may also develop. Anti-MAG neuropathy predominantly affects males in their 50s or 60s, with an estimated incidence of about 1 in 100,000.

Pathogenesis of Anti-MAG Neuropathy

Myelin-associated glycoprotein (MAG) is a glycoprotein that is specific to Schwann cells, responsible for producing myelin in the peripheral nervous system to support nerve cells. Myelin is a vital component of neurons, enabling the efficient transmission of electrical impulses along nerve axons. However, in the case of anti-MAG neuropathy, the immune system generates IgM antibodies in the bloodstream that specifically target and bind to MAG. This binding process interferes with the normal signaling function of MAG, preventing Schwann cells from initiating myelin production. Consequently, peripheral nerve function becomes compromised.

Diagnostics Development of Anti-MAG Neuropathy

Early identification and accurate diagnosis are crucial for effective intervention and management of the anti-MAG neuropathy. The main diagnostic measures include neurological examination, electromyography, serum antibody testing, and biomarker testing.

Neurological Examination

This method involves nerve conduction studies, nerve biopsy and imaging studies to evaluate the structure, electrical conduction and extent of damage to the peripheral nerves.


This test involves the insertion of fine needles into muscles to record their electrical activity, helping to identify abnormal nerve-muscle interactions and assess the involvement of motor nerves.

Serum Antibody Testing

Blood samples are analyzed to identify the presence of specific antibodies, such as anti-MAG antibodies, through techniques like enzyme-linked immunosorbent assay (ELISA) or immunoblotting.

Biomarker Testing

Other important biological indicators include elevated cerebrospinal fluid protein and elevated IgM monoclonal levels. Serum or spinal fluid may be drawn for testing.

Therapeutics Development of Anti-MAG Neuropathy

  • Targets of Anti-MAG Neuropathy Therapy Development
Target Description
B Cells and Plasma Cells B cells and plasma cells are responsible for the production of anti-MAG antibodies. Targeting these cells can be an effective strategy to reduce antibody levels and prevent further damage to the peripheral nerves. For example, rituximab is a monoclonal antibody targeting CD20-positive B cells. By depleting B cells, rituximab reduces the production of anti-MAG antibodies and is one of the most promising drugs for the therapeutics of anti-MAG neuropathy.
Immune Modulation Modulating the immune response is another target of therapeutic development. By regulating the immune system's activity, it is possible to suppress the abnormal immune response that produces anti-MAG antibodies. Immunosuppressive agents, such as Cyclophosphamide, have demonstrated efficacy by dampening the immune response and reducing antibody levels.
