Also, microglia from MS patients show increased expression of BIP, CHOP, and p-eIF2α (Mháille et al., 2008; Cunnea et al., 2011; McMahon et al., 2012), and microglia from animals with EAE also express BiP, GRP94, CHOP, and p-eIF2α (Ní Fhlathartaigh et al., 2013; Ta et al., 2016). The gene discussed is EIF2A; the disease is myeloid sarcoma.
