H1-0 and autoimmune hepatitis: As shown in Figure 3(a), most (4/5) of Con A-injected recipients expressed higher titer of anti-histone H1 Ab at day 7 after OLT and remained at an elevated level compared with the baseline (day 0), while anti-histone H1 Ab was not detected in the serum of OLT (DA-LEW) without Con A treatment or transiently induced in the course of Con A-induced autoimmune hepatitis (Figure 3(c)) [13, 14, 18].
