LGI1 and viral encephalitis: For LGI1 encephalitis patients (n = 6) and HDs (n = 4), miR-2467-5p expression in PBMCs was negatively associated with the serum levels of PDCD1 (r = −0.867, p = 0.002) and CSF3 (r = −0.721, p = 0.023), but favorably correlated with the serum level of CCL15 (r = 0.746, p = 0.017) (Fig. 6V–X).
