RIG-I and dsRNA-Induced IFNβ Activation
Except for viruses that initiate RNA synthesis with a protein primer (e.g., picornaviruses), most RNA viruses initiate RNA synthesis with an NTP, and at least some of their viral pppRNAs remain unblocked during the infection. Consistent with this, most viruses require RIG-I to mount an innate immune response, whereas picornaviruses require mda-5. We have examined a SeV infection whose ability to induce interferon depends on the generation of capped dsRNA (without free 5′ tri-phosphate ends), and found that this infection as well requires RIG-I and not mda-5. We also provide evidence that RIG-I interacts with poly-I/C in vivo, and that heteropolymeric dsRNA and poly-I/C interact directly with RIG-I in vitro, but in different ways; i.e., poly-I/C has the unique ability to stimulate the helicase ATPase of RIG-I variants which lack the C-terminal regulatory domain

Global Monetary Order and the Liberal Order Debate
AbstractThe recent “liberal international order” (LIO) debate has been vague about the institutions and issue areas that constitute the order. This is likely driven by competing views of “liberal” and, perhaps more importantly, by security scholars dominating the debate. From the perspective of scholars who explore the elements of the global monetary order (reserve currencies, international financial institutions, and central banks), the picture is different. Where security scholars point to a decline in US influence, scholars of global monetary politics see continued US dominance. Moreover, monetary prominence has been a precondition for the viability of great power projects of order building more generally. This symposium offers such a counter narrative. While the security challenges are real, the crises of the last decade have actually reinforced the centrality of the US dollar and American financial power in the international system
