Pathogenic antibodies

Pathogenic vs. non-pathogenic anti-PF4/heparin antibodies

Novel monoclonal antibodies against pathogenic Leptospira

Background Leptospirosis is a zoonotic disease caused by pathogenic bacteria belonging to the genus Leptospira and more than 1 million cases occur worldwide annually. Several mammals may carry the agent, and rats are the most important source of human infection in urban settings. The Leptospira surface proteins have an important role during pathogen infection and some of these allow the differe...

[Pathogenic mechanisms of the anti-phospholipid antibodies].

The antiphospolipid syndrome (APS) is an autoimmune disease characterized by recurrent fetal loss, thrombotic events (arterial or venous) and hemocytopenic disorders associated to high titers of circulating aPL. Two variants of the APS have been described. Primary APS is a clinical entity without evidence of any other autoimmune disease and secondary APS is a clinical disorder mainly associated...

Pathogenic and Epiphenomenal Anti-DNA Antibodies in SLE

The discoveries of natural and the development of manufactured highly efficient catalytic antibodies (abzymes) opens the door to many practical applications. One of the most fascinating is the use of such antibodies in human therapy and prevention (vaccination), of cancer, AIDS, autoimmune diseases. A special entity of naturally occurring DNA hydrolytic anti-DNA antibodies is emerging within pa...

Neurofilament light as an immune target for pathogenic antibodies.

Antibodies to neuronal antigens are associated with many neurological diseases including paraneoplastic neurological disorders, epilepsy, amyotrophic lateral sclerosis and multiple sclerosis. Immunization with neuronal antigens such as neurofilament light (NF-L), a neuronal intermediate filament in axons, has been shown to induce neurological disease and spasticity in mice. Also, although antib...
