alpha-bag cell peptide ( alpha-bcp ) , one of the multiple secretory products of the precursor to the egg-laying hormone ( proelh ) produced by the neurosecretory bag cells of aplysia , has been variously claimed to have excitatory or inhibitory feedback effects on the cells which secrete it and to exert some of these effects via a reduction in camp levels .
