HSP90AB1 and psoriasis: The concentrations of anti-Hsp90α antibodies in the active phase showed a moderate positive linear relationship with the concentrations of anti-Hsp90α antibodies in the remission phase of psoriasis (R = 0.58; p = 0.000000) (Fig. 3c) and the concentrations of anti-Hsp90β antibodies in the active phase showed a strong positive linear relationship with the concentrations of anti-Hsp90β antibodies in the remission phase of psoriasis (R = 0.74; p = 0.000000) (Fig. 3d).
