Cytokines, infection blockers;http://f1000.com/8799956?key=fz8tv2xg8np86l0 Patients infected by Candida albicans -- the causative agent of chronic mucocutaneous candidiasis disease (CMCD), an infection of the oral and genital mucosae, skin, and nails -- and possibly Staphylococcus aureus, often have mutations in genes encoding interleukin-17 receptor A (IL-17RA) and IL-17F, suggesting an essential role of these cytokines in protecting against such infections.A. Puel et al., "Chronic mucocutaneous candidiasis in humans with inborn errors of interleukin-17 immunity," linkurl:Science,;http://www.ncbi.nlm.nih.gov/sites/entrez/21350122?dopt=Abstract&holding=f1000%2Cf1000m 332:65-8, 2011. Evaluated by Dan Conrad, Virginia Commonwealth Univ; Jay Kolls, LSU Health Sciences Cen; Klaus Ley, La Jolla Inst for Allergy & Immunology; Sarah Gaffen, Univ Pitt; Joshua Milner, National Inst of Allergy and Infectious Diseases. linkurl:Free F1000 evaluation;http://f1000.com/8799956?key=fz8tv2xg8np86l0 linkurl:2. AMPK structure revealed;http://f1000.com/9287956?key=lfnwb36yh6w6n0k Researchers detail the crystal structure of AMP-activated protein kinase (AMPK), which helps regulate cell metabolism and has been implicated in diseases such as type 2 diabetes, obesity and cancer. The results provide new information about how nucleotide binding and subsequent phosphorylation of the activation loop affects the catalytic activity of the enzyme.B. Xiao et al., "Structure of mammalian AMPK and its regulation by ADP," linkurl:Nature,;http://www.ncbi.nlm.nih.gov/sites/entrez/21399626?dopt=Abstract&holding=f1000%2Cf1000m 472:230-33, 2011. Evaluated by Chris Marshall and Mitsuhiko Ikura, Ontario Cancer Inst; Eduardo Rial, CSIC; Paul Clarke, Univ Dundee; John Kyriakis, Tufts Med Cen. linkurl:Free F1000 evaluation;http://f1000.com/9287956?key=lfnwb36yh6w6n0k linkurl:3. New nano-communication?;http://www.the-scientist.com/news/display/57991/

Bacteria may be able to exchange proteins and genetic materials via newly identified intercellular nanotube structures, possibly representing a novel form of interspecies communication -- a finding that could shed light on how antibiotic resistance spreads.G.P. Dubey and S. Ben-Yehuda, "Intercellular nanotubes mediate bacterial communication," linkurl:Cell,;http://www.ncbi.nlm.nih.gov/sites/entrez/21335240?dopt=Abstract&holding=f1000%2Cf1000m 144:590-600, 2011. Evaluated by Ramanujam Srinivasan, Mithilesh Mishra and Mohan Balasubramanian, National Univ Singapore; Mélanie Hamon and Pascale Cossart, Institut Pasteur; Fabio Bagnoli and Rino Rappuoli, Novartis; Adrian Mehlitz and Roy Gross, Univ Würzburg. linkurl:Free F1000 evaluation;http://f1000.com/8905957?key=7rysr015hg6hgqw linkurl:4. A long-term memory chemical;http://www.f1000biology.com/article/9nwdhhcqp4ttzjx/id/8941962 During the formation of long-term memories, neurons in the brain must import lactate, which forms when an energy reserve molecule called glycogen is broken down by specialized brain cells known as astrocytes. A. Suzuki, et al., "Astrocyte-neuron lactate transport is required for long-term memory formation," linkurl:Cell,;http://www.ncbi.nlm.nih.gov/sites/entrez/21376239?dopt=Abstract&holding=f1000%2Cf1000m 144:810-23, 2011. Evaluated by James Bamburg, Colo St Univ; David Wolfer, Univ Zurich; Faraz Sultan and David Sweatt, Univ Ala Birmingham; Karl-Peter Giese, King's Coll, UK. linkurl:Free F1000 evaluation;http://www.f1000biology.com/article/9nwdhhcqp4ttzjx/id/8941962 linkurl:5. Selfing RNA?;http://f1000.com/9660956?key=5hgl3f99rcspp74 Researchers describe an RNA polymerase ribozyme that can synthesize another naturally occurring RNA ribozyme, hinting at the possibility of a self-replicating RNA molecule -- a key requirement of the RNA world hypothesis, which posits that life began with RNA molecules making copies of themselves.A. Wochner et al., "Ribozyme-catalyzed transcription of an active ribozyme," linkurl:Science,;http://www.ncbi.nlm.nih.gov/sites/entrez/21474753?dopt=Abstract&holding=f1000%2Cf1000m 332:209-12, 2011. Evaluated by Yan Xu and Makoto Komiyama, Univ Tokyo; Peter Unrau, Simon Fraser Univ; Niles Lehman, Portland State Univ; Michael Yarus, Univ Colorado at Boulder; William Scott, Univ California at Santa Cruz. linkurl:Free F1000 evaluation;http://f1000.com/9660956?key=5hgl3f99rcspp74 linkurl:6. Molding microtubules;http://www.f1000biology.com/article/qsl27r6mpfjqxfm/id/5378958 MEC-17, an enzyme that is crucial to the function of touch receptors in C. elegans, takes part in the post-translational modification of alpha-tubulin essential for proper microtubule structure and function in neurons. J.S. Akella, et al., "MEC-17 is an alpha-tubulin acetyltransferase," linkurl:Nature,;http://www.ncbi.nlm.nih.gov/sites/entrez/20829795?dopt=Abstract&holding=f1000%2Cf1000m 467:218-22, 2010.

Cell division with a twist;http://www.the-scientist.com/news/display/57981/ Researchers identify thin spiral fibers that appear to physically cut one daughter cell from the other during the final stages of mitosis, elucidating a fundamental biological process and possibly leading to a better understanding of cancer, which can be caused by improper cell division. J. Guizetti et al., "Cortical constriction during abscission involves helices of ESCRT-III-dependent filaments," linkurl:Science,;http://www.ncbi.nlm.nih.gov/sites/entrez/21310966?dopt=Abstract&holding=f1000%2Cf1000m 331:1616-20, 2011.
