Therefore, we focused on IL1β and found that approximately half of the cells expressing low (as shown by arrows in Figure 4b) and high (as shown by arrowheads in Figure 4b) levels of SF1 in the adrenal zF, that is, adrenocortical cells, exhibited strong immunostaining for IL1β in OM, whereas few cells displayed this staining in YM (Figure 4b,c). Here, IL1B is linked to ocular melanoma.
