Neurite-stimulating activity of secretions from the Hirudo medicinalis salivary gland in cultured sensory neurons
Basic science published in Ross Fiziol Zh (2001)
Abstract
Components of leech (Hirudo medicinalis) salivary gland secretion (high molecular mass bdelin B, bdellastasin, eglin C, destabilize) were used to investigate their neurotrophic effect on organotypic culture of dorsal root ganglia of the 10-11-day old chicken embryos. Destabilize and high molecular mass bdelin B in concentrations of 0.01, 0.02, 0.05 and 0.1 ng/ml, bdellastasin in concentrations of 0.02 and 0.05 ng/ml, eglin C in concentrations of 0.1 ng/ml exhibit neurite-stimulating effect as compared to the control.

Summary
Bdellin B, bdellastasin, eglin C, and destabilase at nanogram-per-mL concentrations exert neurite-stimulating effects on chick embryo dorsal root ganglia.
Why This Matters for Hirudotherapy
This laboratory study investigated the neurotrophic effects of four purified components of Hirudo medicinalis salivary gland secretion—high molecular mass bdelin B, bdellastasin, eglin C, and destabilize—on organotypic cultures of dorsal root ganglia from 10-11-day-old chicken embryos. Destabilize and high molecular mass bdelin B (0.01-0.1 ng/ml), bdellastasin (0.02 and 0.05 ng/ml), and eglin C (0.1 ng/ml) exhibited neurite-stimulating effects compared to control. This is directly relevant to ASH's domain, identifying specific leech secretome components with potential neurotrophic bioactivity. The caveat is that this is an in vitro organotypic culture study in avian sensory neurons, with no data on mammalian systems, in vivo effects, or therapeutic applicability to human neurological conditions.
