ADAMTSL5 expression pattern observed in immune-related psoriasis induced by anti-PD-1 was similar to that observed in plaque-type psoriasis (Figure 5A), even though ADAMTSL5 antigen was not always detectable in all psoriasis specimens (3 of 6 psoriasis patients were ADAMTSL5+). Here, ADAMTSL5 is linked to psoriasis.
