title: Layers upon layers: MHC class I acts in the retina to influence thalamic segregation.
abstract: Recent research has introduced the major histocompatibility complex class I (MHCI) genes as unexpected players in structural and synaptic plasticity in the central nervous system. In this issue of Neuron, Xu et al. redirect current theory by providing strong evidence for the inner retina as a site of action of MHCI proteins in retinogeniculate refinement.
