The titers of the anti-NMDAR1 autoantibodies in our mice (1 to 200 dilution in IHC) are 1–3 orders of magnitude lower than the titers of anti-NMDAR1 autoantibodies in the blood of patients with anti-NMDAR1 encephalitis (1 to 2,000–500,000 dilution in IHC) [25]. Here, GRIN1 is linked to encephalitis.
