Furthermore, we retrospectively screened for anti-CRMP2 Abs in 46 samples from other cases with neuro-cytoplasm immunostaining on rat brain sections, which included 15 autoimmune diseases, 6 cerebrovascular diseases, 5 infectious encephalitis, 8 encephalitis with unclear causes, 1 anaplastic astrocytoma, and 11 other neurological disorders (Figure 2 and Supplementary Table S2). Here, DPYSL2 is linked to viral encephalitis.
