[19-12-2017]Scientists highlight the functional significance of NS3 in noroviral life cycle

Noroviruses are a genetically diverse group of non-enveloped, positive-stranded RNA viruses belonging to genus Norovirus of the family Caliciviridae. They arefurther segregated into seven genogroups (GI-GVII), three of which cause diseases exclusively in humans (GI, GII, and GIV). Human noroviruses (HuNoVs) are now considered the leading cause of viral gastroenteritis in humans across the globe...

[15-12-2017]Natural insect virus baculovirus has evolved a distinct strategy to suppress the host immune system

Melanization is one of important modules in insect defense system. It consists of a cascade of clip-domain serine proteases (cSPs) that converts the zymogen prophenoloxidase (PPO) to active phenoloxidase (PO), which is negatively regulated by serpins. PO then catalyses the formation of melanin that physically encapsulates certain pathogens. Parasites and bacteria have evolved to produce specifi...

[14-12-2017]Chinese Researchers demonstrated that a virus can suppress the N-end rule pathway

The N-end rule pathway is a proteasome dependent proteolytic system that recognizes and degrades proteins containing N-degrons, and has emerged as a key regulator of various processes. Viruses manipulate diverse host pathways to facilitate viral replication and evade antiviral defenses. However, it remains unclear if viral infection has any impact on the N-end rule pathway.

[24-11-2017]Chinese Researchers Reveal the Function of Prion Protein in Tumorigenesis

Prion protein (PrP) is a glycosylphosphatidylinositol anchored protein widely expressed in central nervous system, lymphoreticular system and GI tract. It has been attributed to neurodegenerative diseases such as prion disease and alzheimers disease. However, normal functions of PrP remains in-completely understood.
