HNRNPA1 and immune system disorder: Figure 8(a) showed the first interaction network in C/B group. The differential proteins under this network were mainly related to the functions of skin diseases, immune diseases, and inflammatory diseases. The key proteins that interacted with other proteins were HNRNPA1, KRT14, SFN, and so on.  Figure 8(b) showed the third interaction network in D/B group.
