abstract = {Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is
the most common autoimmune encephalitis related to
autoantibody-mediated synaptic dysfunction. Cerebrospinal
fluid-derived human monoclonal NR1 autoantibodies showed low
numbers of somatic hypermutations or were unmutated. These
unexpected germline-configured antibodies showed weaker
binding to the NMDAR than matured antibodies from the same
patient. In primary hippocampal neurons, germline NR1
autoantibodies strongly and specifically reduced total and
synaptic NMDAR currents in a dose- and time-dependent
manner. The findings suggest that functional NMDAR
antibodies are part of the human naïve B cell repertoire.
Given their effects on synaptic function, they might
contribute to a broad spectrum of neuropsychiatric symptoms.
