Lectin cytochemistry of normal rat central nervous system (CNS) was performed on formalin-fixed, paraffin-embedded sections by using 14 lectins and light and electron microscopy. Hippocampal neurons reacted positively with Griffonia (Bandeiraea) simplicifolia lectin I (GSL-I), Griffonia (Bandeiraea) simplicifolia lectin II (GSL-II) and Vicia villosa agglutinin (VVA); neurons in the cornu ammonis (CA) 2 region reacted positively with GSL-I and GSL-II, and neurons in the CA2 and CA3 regions reacted with VVA. Cortical neurons reacted positively with GSL-I and VVA. Cerebellar Purkinje cells and granule cells were reactive with Phaseolus vulgaris leukoagglutinin (PHA-L). Cerebellar nucleus neurons were also reactive with PHA-L and VVA. Reactivity with GSL-I, GSL-II, VVA and PHA-L was observed only on the neuronal cell surface. The present findings demonstrate the differences between cerebral and cerebellar neurons in reacting with glycoconjugates.
