Toll-like receptors (TLRs) are crucial in the innate immune response to pathogens, in that they recognize and respond to pathogen associated molecular patterns, which leads to activation of intracellular signaling pathways and altered gene expression. Vaccinia virus (VV), the poxvirus used to vaccinate against smallpox, encodes proteins that antagonize important components of host antiviral defense. Here we show that the VV protein A52R blocks the activation of the transcription factor nuclear factor kappa B (NF-kappa B) by multiple TLRs, including TLR3, a recently identified receptor for viral RNA. A52R associates with both interleukin 1 receptor-associated kinase 2 (IRAK2) and tumor necrosis factor receptor-associated factor 6 (TRAF6), two key proteins important in TLR signal transduction. Further, A52R could disrupt signaling complexes containing these proteins. A virus deletion mutant lacking the A52R gene was attenuated compared with wild-type and revertant controls in a murine intranasal model of infection. This study reveals a novel mechanism used by VV to suppress the host immunity. We demonstrate viral disabling of TLRs, providing further evidence for an important role for this family of receptors in the antiviral response.

Includes 41 copies of plans of Royal Navy ships, ranging in date from 1784 to 1816. Some of the ships included are the Bonne Citoyenne, Niagara, Epervier, Comet, Contest, Ferret, Childers, Anacreon, Florida, Hind, Hermes, Psyche, Princess Charlotte, Contest, Prince Regent, Caroline, Thetis, Statira, Forte, Pelican, Crescent, Euryalus, Chesapeake, Acasta, Banterer, Leda, Endymion, Amphion, President, Tonnant, Ramillies, Boyne, and St. Lawrence. Many of these ships were used by the British during the War of 1812. The original plans are at the National Maritime Museum in Greenwich, London. Also included is a copy of a handwritten chart with the number and size of the British and United States Squadrons on Lake Ontario, March 1814 (during the War of 1812). This includes the number and caliber of long guns and carronades, as well as the weight of metal, for different ships. British ships include the Prince Regent, Princess Charlotte, Wolfe, Royal George, Melville, Moira, Sir Sidney Smith, and Beresford. American ships include the [General] Pike, Madison, Oneida, Sylph, Gen’l Tompkins[?], Conquest, Fair American, Ontario, Pert, Asp, and Lady of the Lake. Also included is a copy of a map titled “Track of the Action”, tracking the movements of the HMS Java and the USS Constitution, dated December 29, 1812, and a copy of a map of Lake Champlain and Plattsburgh Bay showing the position of a vessel(s), undated.

OBJECTIVES: Membrane-targeted application of complement inhibitors may ameliorate ischemia/reperfusion (I/R) injury by directly targeting damaged cells. We investigated whether Mirococept, a membrane-targeted, myristoylated peptidyl construct derived from complement receptor 1 (CR1) could attenuate I/R injury following acute myocardial infarction in pigs. METHODS: In a closed-chest pig model of acute myocardial infarction, Mirococept, the non-tailed derivative APT154, or vehicle was administered intracoronarily into the area at risk 5 min pre-reperfusion. Infarct size, cardiac function and inflammatory status were evaluated. RESULTS: Mirococept targeted damaged vasculature and myocardium, significantly decreasing infarct size compared to vehicle, whereas APT154 had no effect. Cardioprotection correlated with reduced serum troponin I and was paralleled by attenuated local myocardial complement deposition and tissue factor expression. Myocardial apoptosis (TUNEL-positivity) was also reduced with the use of Mirococept. Local modulation of the pro-inflammatory and pro-coagulant phenotype translated to improved left ventricular end-diastolic pressure, ejection fraction and regional wall motion post-reperfusion. CONCLUSIONS: Local modification of a pro-inflammatory and pro-coagulant environment after regional I/R injury by site-specific application of a membrane-targeted complement regulatory protein may offer novel possibilities and insights into potential treatment strategies of reperfusion-induced injury.
