Yet, the precise mechanism by which TTX blocks voltage-gated sodium (Na V) channels is not fully understood. Here molecular dynamics simulations are used to elucidate how TTX blocks mammalian voltage-gated sodium (Nav) channels and why it fails to be effective for the bacterial sodium channel, Na V Ab.1B) in TTX block of Na V channels [5] and [8] . Thus, the guanidine group of TTX may interact with the outer charged ring more intimately, rather than protruding into the filter. Here the inhibition of Na V Ab and Na V 1.4 by TTX is examined in atomic detail using molecular dynamics (MD) simulations.
Tetrodotoxin blocks action potentials in nerves by binding to the pores of the voltage-gated, fast sodium channels in nerve cell membranes, essentially preventing any affected nerve cells from firing by blocking the channels used in the process.
