In human patients with autoimmune, viral, and bacterial diseases, the generation of
antibodies (Abs) to foreign antigens and/or autoantibodies to self‐antigens usually occurs …

Catalytic antibodies made it feasible to develop new catalysts, which had previously been
the subject of research. Scientists have discovered natural antibodies that can hydrolyze …

The pathologic role of autoantibodies in autoimmune disease is widely accepted. Recently,
we reported that anti-myelin basic protein (MBP) serum Abs from multiple sclerosis (MS) …

Acquired haemophilia A (AHA) is a rare bleeding disorder characterized by the sudden
generation of autoantibodies against factor VIII (FVIII) in individuals with no previous history …

This work is the first to demonstrate that class G immunoglobulins (IgGs) in patients with
multiple sclerosis and healthy individuals have the ability to catalyze the dismutation …

Idiotypic networks, after being a dominating paradigm for more than a decade, have fallen
out of fashion in parallel with the rapid success of molecular immunobiology. Today signs of …

Antibodies are protein molecules whose primary function is to recognize antigens. However,
recent studies have demonstrated their ability to hydrolyze specific substrates, such as …

Envenoming by the contact of human skin with Lonomia obliqua caterpillars promotes a
hemorrhagic syndrome characterized by a consumptive coagulopathy. Losac (Lonomia …

Antibodies with nucleophilic or catalytic properties often have these characteristics encoded
in their germ line genes. Because hydrolytic activity has been reported to be associated with …

Background Because of limited impact on infant morbidity, mortality, and vitamin A status,
