In multiple sclerosis patients, low MxA levels reflect reduced efficacy of IFN therapy

Multiple sclerosis (MS) is a multi-organ autoimmune disease affecting the central nervous system of young adults and is the most common autoimmune inflammatory demyelinating disease worldwide. It is a disabling neurological disease; local paralysis, incoordination of walking, double vision, and physical weakness are the prevalent symptoms of MS.

IFN-beta is an efficacious first-line drug for relapsing MS, by reducing the relapse rate, disability and magnetic resonance imaging (MRI) disease burden. Up to 30–40% of MS patients treated with IFN may develop neutralizing antibodies (NAbs) to IFN-β. NAbs are associated with reduced treatment efficacy, disease relapse, and progression.

MxA (myxovirus resistance protein 1), the product of the MX1 gene plays an important role in the antiviral activity of the organism. It is expressed in response to IFN-β (or IFN-α) in the cytoplasm of sensitive cells. In MS patients, MxA correlates with therapeutic actions of IFN and is not influenced by disease activity. The absence of MxA reflects the complete loss of IFN bioactivity due to the presence of NAbs.

MxA is a marker of viral infection

12081

In newborns and infants

MxA (myxovirus resistance protein 1) differentiates patients with a viral infection from patients with bacterial infection and healthy controls.

Determination of MxA is used to avoid the inappropriate use of antibiotics, especially in newborns. Moreover, the immature immune system of newborns and infants poorly respond to infection.

In postoperative care - Distinguish virus infection

Many patients suffer febrile diseases soon after allogeneic stem cell transplantation. MxA is a useful marker to detect viral infections and distinguish them from acute graft-versus-host disease after allogeneic cell transplantation.

IFN-α treatment of hepatitis B and C patients 

MxA, a protein with selective activity against certain viruses, is an accepted specific indicator of type I IFN activity.

MxA expression may be used to asses effectivity of IFN-α therapy of HBV and HCV patients. Hepatitis C virus (HCV) patients who express increased amounts of MxA mRNA in their PBMC during IFN-α treatment are most likely to obtain a long-term benefit. Another study showed that MxA mRNA induced by IFN-α might predict sustained virologic responses to IFN-α treatment in chronic HBV patients.
