Effects of two classes of pyrethroids, permethrin and resmethrin (type I), cypermethrin and deltamethrin (type II), on basal (calmodulin-deficient) and calmodulin stimulated activities of Ca2+ ATPase and adenylate cyclase from rat brain were studied in vitro.

16678970 Wu ZZ, Chen SR, Pan HL: Signaling mechanisms of down-regulation of voltage-activated Ca2+ channels by transient receptor potential vanilloid type 1 stimulation with olvanil in primary sensory neurons. Neuroscience. 2006 Aug 11;141(1):407-19. Epub 2006 May 6.

Furthermore, calcineurin (protein phosphatase 2B) inhibitors (deltamethrin and FK-506) eliminated the effect of olvanil on voltage-activated Ca (2+) channel current.
Calmodulin antagonists (ophiobolin-A and calmodulin inhibitory peptide) largely blocked the effect of olvanil and capsaicin on voltage-activated Ca (2+) channel current.

The calcineurin inhibitor deltamethrin did not interfere with CGS 21680.
It is suggested that the transduction mechanism of A (2A) receptors to inhibit NMDA receptor channels is the phospholipase C/InsP (3)/calmodulin and calmodulin kinase II pathway.

In addition, blocking Ca2+/calmodulin-dependent protein kinase II (CamKII) with KN-62 partially reversed the action of GABA, suggesting that AC3 may also be involved in this effect.
Furthermore, blocking calcineurin with deltamethrin, FK-506 or cyclosporin A blocked the inhibitory effect of GABA on [cAMP] i, supporting the involvement of AC9 in this effect.

In addition, deltamethrin-1R induced a transient increase of [Ca2+] i mobilization in the thymocyte suspension after 10 min of in vitro treatment, and substantially reduced the rate of calcium-calmodulin (Ca/CaM)-dependent protein dephosphorylation in in vivo treated animals (25 mg deltamethrin/kg for 24 hr).

Previous work demonstrated increases in the expression of Ca (2+)/calmodulin-dependent protein kinase 1-gamma (Camk1g) mRNA following acute deltamethrin and permethrin exposure.

Blockade of calmodulin by calmidazolium or blockade of CaM kinase II with either KN93 or autocamtide-2-related inhibitory peptide each prevents the rundown; blockade of the phosphatase calcineurin with either cyclosporin A or deltamethrin increases the rundown.

The type II pyrethroid insecticides cis-cypermethrin (c-Cyp), trans-cypermethrin, deltamethrin (Delt), and fenvalerate A alpha (Fen), as well as the type I pyrethroid insecticides cis- and trans-permethrin and S-bioallethrin, were unable to inhibit the phosphatase activity of purified calcineurin under conditions of maximal activation by Ca2+ and calmodulin.

Western immunoblotting revealed PPase 2B to be present in cytoskeletal EC fractions, with specific PPase 2B inhibitors such as cyclosporin (200 nM) and deltamethrin (100 nM to 1 microM) attenuating thrombin-induced cytoskeletal protein dephosphorylation, including EC MLC dephosphorylation.

Dev Biol. 1996 Nov 25;180(1):284-96.

In this regard, the calcineurin inhibitor deltamethrin inhibited the Ca2+ ionophore-induced dephosphorylation.

1315545 Enan E, Matsumura F: Specific inhibition of calcineurin by type II synthetic pyrethroid insecticides. Biochem Pharmacol. 1992 Apr 15;43(8):1777-84.

The inhibitory action of synthetic pyrethroids and some chlorinated hydrocarbon insecticides on the neural calcium-calmodulin-dependent protein phosphatase, calcineurin, was studied using one radiotracer and two colorimetric methods.
It was found that all insecticidal Type II pyrethroids (cypermethrin, deltamethrin and fenvalerate) are potent inhibitors of isolated calcineurin from bovine brain.

The inhibitory effect of calcineurin could be blocked by the pyrethroid deltamethrin, indicating inhibition of SV channels by calcineurin via dephosphorylation.
SV currents were potently modulated by the Ca2+-dependent, calmodulin-stimulated protein phosphatase 2B (calcineurin).

The short-circuit current value (estimate of ion transport) was increased by each of the eight pyrethroids tested, with the following order of potency: lambda-cyhalothrin > deltamethrin > alpha-cypermethrin = beta-cyfluthrin > bioallethrin > permethrin > bioresmethrin > phenothrin.
Finally, the stimulation by pyrethroids was inhibited by indomethacin and W7 (inhibitors of cyclooxygenases and the Ca2+/calmodulin system, respectively).

The Ca2+/calmodulin-dependent phosphatase calcineurin may have physiological and pathological roles in neurons, but little is known about the roles of the enzyme in glial cells.
Deltamethrin (20 nM), another calcineurin inhibitor, had a similar protective effect, whereas okadaic acid did not.

Inclusion of purified calcineurin plus its coactivators 200 nM Ca2+ and calmodulin in the patch pipette decreases Po,peak to 0.48 +/- 0.10.
The calcineurin-stimulated decrease of Po,peak in cells co-transfected with C alpha-PKA is blocked by 800 nM deltamethrin, a calcineurin inhibitor.

Furthermore, intracellular dialysis of deltamethrin or cyclosporin A, the specific calcineurin (protein phosphatase 2B) inhibitors, but not okadaic acid (a selective protein phosphatase 1/protein phosphatase 2A inhibitor), abolished the effect of capsaicin on I (Ca).
