Antinociception and VGSC-modulation of BmK IT2 and BmK AS—1. The results from nociceptive flexion reflex and plantar radiation heat showed: BmK IT2 (a depressant insect-selective neurotoixn) and BmK AS-1 (a new-type β-1ike neurotoxin) have significant antinociceptive effects on rat peripheral nerve system. The antinociceptive effects of BmK IT2 on the carrageenan-inflamed rats were significantly stronger than those on the normal rats. Whole-cell patch-clamping showed: Both TTX-S and TTX-R Na〓 currents induced from rat DRG neurons were significantly inhibited by BmK IT2 and BmK AS—1, and BmK IT2 was more sensitive to TTX-R than TTX-S component. All the results suggested: the peripheral antinociception of BmK IT2 and BmK AS—1 might be attributed to the inhibitory effects of them on the TTX-S and TTX-R Na〓 channel located on the peripheral ends of rat DRG neurons with small diameter.
