1. A method for inhibiting inflammasome activity in a subject, comprising administering to said subject a connexin 43 hemichannel modulator according to Formula I or Formula II in an amount effective to modulate inflammasome activity.
2. The method according to claim 1 , wherein the modulator is a compound according to Formula I.
3. The method according to claim 1 , wherein the modulator is a compound according to Formula II.
4. The method according to claim 2 , wherein the modulator is tonabersat.
5. A method according to claim 1 , wherein said inflammasome is the NLRP3 inflammasome.
6. A method according to claim 1 , wherein said inhibition of inflammasome activity comprises inhibition of inflammasome activation .
7. The method according to claim 1 , wherein said inhibition of inflammasome activity comprises inhibition of activation of an inflammatory cascade by an inflammasome.
8. The method according to claim 6 , wherein the inflammasome is the NLRP3 inflammasome.
9. The method according to claim 7 , wherein the inflammasome is the NLRP3 inflammasome.
10. The method according to claim 1 , wherein the subject has lung inflammation, an inflammatory cardiac insult, acute respiratory distress syndrome, acute lung injury, pericardial effusion, pericarditis, or systemic inflammatory response syndrome.
11. The method according to claim 10 , wherein the subject is human, the connexin 43 hemichannel modulator is tonabersat or a prodrug of tonabersat, and the connexin 43 hemichannel modulator is administered during or before lung inflammation.
12. A method according to any of claim 1 , 2 , 4 - 9 , 10 or 11 , wherein said connexin 43 hemichannel modulator is administered by oral, systemic, intranasal, parenteral, transdermal or ocular administration, or by implantation or infusion.
