A TAP1 null mutation leads to an enlarged olfactory bulb and supernumerary, ectopic olfactory glomeruli
Major histocompatibility class I Educational Toys (MHCI) molecules are well known for their immunological role in mediating tissue graft rejection.Recently, these molecules were discovered to be expressed in distinct neuronal subclasses, dispelling the long-held tenet that the uninjured brain is immune-privileged.Here, we show that MHCI molecules a
