Antibodies against alpha-fodrin in Sjoegren's syndrome

Alpha-fodrin is a part of the membrane skeleton and expressed in the majority of mammalian cells. It is cleaved in apoptosis by caspase 3. One of the cleavage products, a 120-kDa protein, represents a neoantigen. Antibodies against that cleavage product of alpha-fodrin have originally been described...

Summary:Alpha-fodrin is a part of the membrane skeleton and expressed in the majority of mammalian cells. It is cleaved in apoptosis by caspase 3. One of the cleavage products, a 120-kDa protein, represents a neoantigen. Antibodies against that cleavage product of alpha-fodrin have originally been described in a murine model of Sjoegren's syndrome. In addition, they are also present in up to 93% of patients with Sjoegren's syndrome, depending on the stringency of the classification used. Although antibodies against alpha-fodrin are observed in other diseases characterized by chronic apoptosis, they are a valuable laboratory marker in the evaluation of Sjoegren's syndrome.
