PLP1 and myeloid sarcoma: In this model, PLP139–151-induced EAE (PLP-induced relapsing–remitting EAE; RR-EAE) symptoms are developed within 1–2 weeks, remitted thereafter, and then relapsed at 3–4 weeks after immunization, indicating that PLP-induced RR-EAE in SJL/J mice shares a certain characteristic with RR-MS [7].
