Koval', N. Kononenko, M. Lutsik, E. Yavorskaya] The surface of unidentified cultured neurons and electrophysiologically identified units RPa1, RPa2, and LPa3 of the snailHelix pomatia was studied using a colloidal gold-labelled endogenous gonad lectin of this molluse (Helix pomatia agglutinin -HPA), which is specific to α-anomer N-acetyl-D-galactosamine, and some other lectins. It was found that only two populations of cultured neurons with a specific ultrastructure typical of peptidergic cells and differing from the ultrastructure of other peptidergic and non-peptidergic neurons possessHPA receptors. These neurons average about 1% of cultured nerve cells. Using a variety of plant lectins withHPA-like specificity (LBA, VVA, SBA) showed that the surface of many peptidergic neurons contains α-anomer-like structures, yet it does not bindHPA. These data were supported in the experiments on identified snall neurons with the use ofSBA. The results suggest a putative role of endogenous lectins in regulation of activity of neurons participating in processes of secretion in the gonads. Plenum Publishing Corporation, 1997 Koval' L.
