Each panel represents molecular pathways that are used by immune molecules at the synapse to regulate synapse formation and/or plasticity. a | Major histocompatibility complex class I (MHCI) molecules are located at synapses, where they act through calcineurin to activate myocyte-specific enhancer factor 2 (MEF2) transcription factors to negatively regulate synapse strength and density. MHCI-dependent activation of MEF2 requires calcium influx through NMDA receptors (NMDARs) and voltage-gated calcium channels (VGCCs), although the molecules linking increases in MHCI expression and increases in NMDAR and VGCC conductance remain unknown (denoted by the question mark). MEF2 can act in concert with fragile X mental retardation protein 1 (FMRP) to stimulate the ubiquitylation of postsynaptic density.
