Increased Autoreactivity of the Complement-Activating Molecule Mannan-Binding Lectin in a Type 1 Diabetes Model

BACKGROUND Diabetic kidney disease is the leading cause of end-stage renal failure despite intensive treatment of modifiable risk factors. Identification of new drug targets is therefore of paramount importance. The complement system is emerging as a potential new target. The lectin pathway of the complement system, initiated by the carbohydrate-recognition molecule mannan-binding lectin (MBL),...

Lectin-Associated Serine Protease Complex of Ficolin and Mannose-Binding Cutting Edge: Complement-Activating

Activation of the Lectin Complement

Monomeric complement-activating IgG paraproteins.

Three patients presented a unique syndrome of recurrent panniculitis with an IgGkappa paraprotein and depletion of the early components of the classical pathway of complement. The IgGkappa paraproteins were monomers with a normal structure, and with no evidence for aggregation, as assessed by electron microscopy and ultracentrifugation. Both heavy and light chains were of normal molecular size ...

mannose-binding lectin mediated complement pathway in autoimmune neurological disorders

multiple sclerosis (ms) is a complex, demyelinating disease of the central nervous system (cns) with variable phenotypic presentations, while guillain-barre syndrome (gbs) is the prototypic acute inflammatory disorder that affects the peripheral nervous system. myasthenia gravis (mg) is a t cell dependent and antibody mediated autoimmune disease. although it has been shown that complement plays...
