We have studied the molecular basis of nervous system repair in invertebrate (Hirudo medicinalis) nerve cells. Unlike in mammals, neurons in invertebrates survive injury and regrow processes to restore the connections that they held before the damage occurred. To identify genes whose expression is regulated after injury, we have used subtractive probes,(More)
To understand the molecular basis of nervous system function in the leech, Hirudo medicinalis, we have isolated four novel cDNAs encoding putative voltage-gated sodium (Na) channel alpha subunits, and have analyzed the expression of these genes in individual neurons of known function. To begin, degenerate oligonucleotide primers were used in combination(More)
