title: A critique of some of the current concepts on the immunopathogenesis of rheumatoid arthritis.
abstract: The interaction of polycations produced during tissue damage and C-reactive protein, and the enzymatic degradation of complement components may be positive mechanisms augmenting immune-complex/complement damage, while reduced phagocytosis and reduced chemotaxis may be negative mechanisms. In cell-mediated immunity, systems consisting of C-reactive protein, proteases, prostaglandins and immune complexes are all potentially capable of negative feedback control.
