Abstract BackgroundFine specificity of anti-citrullinated protein antibodies (ACPAs), in which cross-reactivity exists, varies among patients with rheumatoid arthritis (RA), but it is unclear whether the mechanism of ACPA production is same or different among individuals. Since avidity of serum antibody reflects the direction of immune response, we compared the levels of avidity and cross-reactivity between various ACPAs in a cohort of RA patient.MethodsSera from 180 RA patients positive for anti-cyclic citrullinated peptide (CCP) 2 antibody were screened for positivity of antibodies against CCP1, and citrullnated fibrinogen (cFib), enolase (cEno), and vimentin (cVim) peptides. Avidity of the four ACPAs, and some autoantibodies and antibodies against foreign antigens was determined by an elution assay using sodium thiocyanate solution. Cross-reactivity between different ACPAs was estimated by measuring the inhibition of binding by competitor peptides. ResultsThe prevalence of anti-CCP1, anti-cFib, anti-cEno, and anti-cVim antibodies in the anti-CCP2-positive RA cohort were 37.7%, 38.3%, 15.6%, and 23.9%, respectively. The avidity of ACPAs, except for anti-cVim antibody, was significantly lower than that of antibodies against foreign antigens, while there was a large variety in the avidity of other autoantibodies. At individual levels, the avidity of anti-cVim was significantly higher than that of other ACPAs, and there was a significant correlation in the avidity of anti-CCP and anti-cFib antibodies. Substantial extent of cross-reactivity was seen between different ACPAs, which also showed a fixed hierarchy.ConclusionThe fixed hierarchy in the avidity and cross-reactivity between different ACPAs suggests that the mechanism underlying ACPA production is common to all RA patients. Presence of a dominant antigen that induces whole ACPA response is speculated.

Urinary Glycoprotein

Affinity chromatography, with rabbit anti-(human Tamm-Horsfall glycoprotein) IgG, was applied to the isolation from normal human serum of protein, which is immunologically cross-reactive with the urinary glycoprotein. The antigen-antibody complex was dissociated with the use of sodium thiocyanate solution, a medium which fails to dissociate urinary Tamm-Horsfall glycoprotein-antigen complex. The cross-reactive serum proteins were isolated in amounts of 19-24 mg/l of serum. They have apparent molecular weights, assessed by disc-gel electrophoresis in the presence of sodium dodecyl sulphate, of 125 000, 84 000 and 74 000 respectively, with mobilities differing from that of urinary Tamm-Horsfall glycoprotein. They have a much lower immunoreactivity towards the antibody than does the urinary glycoprotein. Tamm-Horsfall glycoprotein could not be demonstrated in normal serum by the techniques used. The implications of these findings are discussed in terms of pathology involving Tamm-Horsfall glycoprotein.

Dissolution Current

The galvanostatic dissolution of mercury from the surface of glassy carbon into a thiocyanate solution proceeds in accord with theoretical assumptions, as manifested by the constant product of the dissolution current and transition time. Under certain relations between the amount of oxidised mercury and concentration of thiocyanate at the electrode surface, however, a small part of the mercury dissolves at more positive potentials than correspond to the Nernst equation. This dissolution can be accompanied by potential oscillations. The anomalous behaviour is elucidated by the concept about coverage of a certain part of mercury with a film of sparingly soluble compounds of SCN- ions with mercury. This film is formed at the end of the galvanostatic dissolution on certain places of the electrode surface covered with mercury droplets, where SCN- ions are much exhausted as a result of a high current density.
