Graphical abstract showing that NMDAR immunisation drives psychosis-like behaviour in mice, while clozapine reverses this. Upper panel: arrows show NMDAR immunisation producing a mouse exhibiting psychosis-like behaviour, with clozapine reversing this effect. Lower panels: anti-NMDAR antibodies bind neuronal NMDA receptors, which are then eliminated by microglia via phagocytosis, leading to psychosis. Clozapine restores NMDA receptor levels by reducing anti-NMDAR antibody levels, consistent with an immunomodulatory mechanism of action.
