Clathrin-mediated endocytosis, the major pathway for ligand internalization into eukaryotic cells, is thought to be initiated by clustering of clathrin and adaptors around receptors destined internalization. However, here we report that membrane-sculpting F-BAR domain-containing Fer/Cip4 homology domain-only proteins 1 2 (FCHo1/2) were required plasma membrane clathrin-coated vesicle (CCV) budding marked sites CCV formation. Changes in FCHo1/2 expression levels correlated directly with...

Intestinal barrier dysfunction is thought to contribute the development of multiple organ syndrome in sepsis. Although there are similarities clinical course following sepsis, significant differences host response depending on initiating organism and time disease, pathways gut injury vary widely different preclinical models The purpose this study was determine whether timecourse mechanisms intestinal similar disparate mouse sepsis with mortalities. FVB/N mice were randomized receive cecal...

To overcome host defenses, bacterial pathogens of the genus Yersinia inject specific effector proteins into colonized mammalian cells. One such virulence factor, YopJ, inhibits inflammatory response and induces apoptosis immune cells by blocking multiple signaling pathways, including MAPK NF-kappaB pathways. In this study, we show that YopJ exerts its deleterious effects catalyzing acetylation two serine residues in activation loop MAP kinase kinase, MEK2. This covalent modification prevents...

Unlike the alpha subunits of heterotrimeric guanosine triphosphate (GTP)-binding proteins, Ras-related GTP-binding proteins have hitherto been considered not to bind or become activated by tetrafluoroaluminate (AIF4-). However, product proto-oncogene ras in its diphosphate (GDP)-bound form interacted with AIF4 - presence stoichiometric amounts either triphosphatase (GTPase)-activating (GAPs) p120GAP and neurofibromin. Neither oncogenic Ras nor a GAP mutant without catalytic activity produced...

Plague, one of the most devastating diseases in human history, is caused by bacterium Yersinia pestis. The bacteria use a syringe-like macromolecular assembly to secrete various toxins directly into host cells they infect. One such outer protein, YopJ, performs task dampening innate immune responses simultaneously inhibiting MAPK and NFkappaB signaling pathways. YopJ catalyzes transfer acetyl groups serine, threonine, lysine residues on target proteins. Acetylation serine threonine prevents...

Abstract Sepsis is a leading cause of death in the United States, but mechanisms underlying sepsis-induced immune dysregulation remain poorly understood. 2B4 (CD244, SLAM4) cosignaling molecule expressed predominantly on NK cells and memory CD8+ T that has been shown to regulate cell function models viral infection autoimmunity. In this article, we show signaling mediates sepsis lymphocyte dysfunction mortality. expression increased CD4+ septic animals human patients at early time points....

Sepsis-induced intestinal hyperpermeability is mediated by disruption of the epithelial tight junction, which closely associated with perijunctional actin-myosin ring. Myosin light chain kinase (MLCK) phosphorylates myosin regulatory chain, resulting in increased permeability. The purpose this study was to determine whether genetic deletion MLCK would alter gut barrier function and survival from sepsis. MLCK−/− wild-type (WT) mice were subjected cecal ligation puncture assayed for both...

Abstract Wildland firefighting is a niche specialization in the fire service - inherently dangerous with unique risks. Over past decade, fatalities amongst all firefighters have decreased; however, wildland firefighter increased.

Abstract Introduction While invasive fungal infections (IFI) can be deadly for any hospitalized patient, a high-risk subset are those with burn injuries due to their inherently immunocompromised state. There is paucity of literature on IFI in this population, making it difficult evaluate the true risk. This novel study captures data from across US using commercially available multi-institutional dataset derived electronic health record and largest date evaluating mortality associated...

Standardized criteria for mobilization of the post-operative burn patient do not currently exist. Even term "early mobilization" is well defined. Use autologous skin cell suspension (ASCS) with or without split-thickness grafts (STSG) has improved outcomes. The purpose this study to evaluate safety early mobilization, defined as rehabilitation team within 48h surgical treatment, in patients who were treated ASCS and a polylactic acid dressing. This single-center, retrospective review over...
