NoVs exhibit wide host tropisms causing diseases in various mammalians including human. NoVs are genetically diverse, containing six genogroups (GI to GVI) with over 35 genetic genotypes. Noroviruses (NoVs) are a group of non-enveloped, single stranded, positive-sense RNA viruses that constitute the Norovirus genus in the family Caliciviridae.

PLoS Pathog 11(7):Įditor: Jacques Le Pendu, University of Nantes INSERM, U892, FRANCE (2015) A Unique Human Norovirus Lineage with a Distinct HBGA Binding Interface. Taken together, our results reveal a new evolutionary lineage of NoVs selected by HBGAs, a finding that is important for understanding the diversity and widespread nature of NoVs.Ĭitation: Liu W, Chen Y, Jiang X, Xia M, Yang Y, Tan M, et al. In addition, we found that glycerol inhibits OIF binding to HBGAs, potentially allowing production of cheap antivirals against human NoVs. Sequence alignment showed that the major residues contributing to the new HBGA binding interface are conserved among most members of the GII.21, as well as a closely related GII.13 genotype. Here, we characterize a Lewis a (Le a) antigen binding strain (OIF virus) in the GII.21 genotype that does not share the conserved GII binding interface, revealing a new evolution lineage with a distinct HBGA binding interface. Each of the two major genogroups (GI and GII) of human NoVs recognizes a unique set of HBGAs through a distinct binding interface that is conserved within a genogroup, indicating a distinct evolutionary path for each genogroup.

While there are no updates planned, the article does mention ruleset changes and in-game events planned. Today, NCsoft announced that the western service for Lineage will be shut off this June 29th. Not well enough to maintain profitability anyway. Lineage is still going strong in Korea, some unknown number under one million according to Wikipedia, but over here in the west the game just isn’t doing well. Ironically, the designer of Lineage (Jake Song) had previously worked on NEXUS, for Nexon. Lineage entered the scene back in 1998, a year after Ultima Online, and with it brought the little game studio known as NCsoft to an eagerly awaiting pile of money, spawning a sequel as well as shuttling NCsoft into one of the major players nowadays in the MMO industry. Writing this article, I’m reminded of a few random comments placed on the last NCsoft article I wrote (about how NCsoft’s subscription games were performing better than their non-subscription games). Simple answer is no, your account will not work on the Korean version.] I’ve been seeing a lot of searches pointing to this page by players who want to know if their accounts will work on the Korean version when the North American servers shut down.
