Turner, Adnane Achour Viral escape from CD8+ cytotoxic T lymphocyte responses correlates with disease progression and represents a significant challenge for vaccination. Here, we demonstrate that CD8+ T cell recognition of the naturally occurring MHC-I-restricted LCMV-associated...

by Diana N. Medina-Pérez, Beau Wager, Erin Troy, Lihui Gao, Steven J. Norris, Tao Lin, Linden Hu, Jenny A. Hyde, Meghan Lybecker, Jon T. Skare Post-transcriptional regulation via small regulatory RNAs (sRNAs) has been implicated in diverse regulatory processes in bacteria, including virulence. One class of sRNAs, termed trans-acting sRNAs, can affect the stability and/or the translational efficiency of regulated transcripts. In this study, we utilized a collaborative approach that employed data...

Crowe Jr Ross River fever is a mosquito-transmitted viral disease that is endemic to Australia and the surrounding Pacific Islands. Ross River virus (RRV) belongs to the arthritogenic group of alphaviruses, which largely cause disease characterized by debilitating polyarthritis, rash, and fever. There is no specific...

by Christina Paulus, Thomas Harwardt, Bernadette Walter, Andrea Marxreiter, Marion Zenger, Edith Reuschel, Michael M. Nevels Promyelocytic leukemia (PML) bodies are nuclear organelles implicated in intrinsic and innate antiviral defense. The eponymous PML proteins, central to the self-organization of PML bodies, and other restriction factors found in these organelles are common targets of viral antagonism. The 72-kDa immediate-early protein 1 (IE1) is the principal antagonist of PML bodies encoded...

Nguyen, Manfred Rohde, Martin Pilhofer, Wolf-Dietrich Hardt, Mikael E. Sellin Salmonella enterica serovar Typhimurium (S.Tm) infections of cultured cell lines have given rise to the ruffle model for epithelial cell invasion. According to this model, the Type-Three-Secretion-System-1 (TTSS-1) effectors...

Cianciotto, James A. Garnett Chitinases are important enzymes that contribute to the generation of carbon and nitrogen from chitin, a long chain polymer of N-acetylglucosamine that is abundant in insects, fungi, invertebrates and fish. Although mammals do not produce chitin, chitinases have been identified...

by Aashutosh Tripathi, Megha Jain, Mintu Chandra, Sameena Parveen, Rupali Yadav, Brett M. Collins, Sankar Maiti, Sunando Datta Remodelling of the actin cytoskeleton in response to external stimuli is obligatory for many cellular processes in the amoebic cell. A rapid and local rearrangement of the actin cytoskeleton is required for the development of the cellular protrusions during phagocytosis, trogocytosis, migration, and invasion. Here, we demonstrated that EhC2B, a C2 domain-containing protein,...

by Qinghe Li, Fei Wang, Qiao Wang, Na Zhang, Jumei Zheng, Maiqing Zheng, Ranran Liu, Huanxian Cui, Jie Wen, Guiping Zhao As a canonical adaptor for the Toll-like receptor (TLR) family, myeloid differentiation primary response protein 88 (MyD88) has crucial roles in host defense against infection by microbial pathogens, and its dysregulation might induce autoimmune diseases. Here, we demonstrate that the chicken Cullin 3-based ubiquitin ligase adaptor Speckle-type BTB–POZ protein (chSPOP) recognizes...
