Abstract:
... The improvement of disease resistance is vital in aquaculture as diseases are one of the serious threats to successful aquaculture. Understanding of molecular mechanisms underlying disease resistance is important in improving resistance against diseases. The pIgR (polymeric immunoglobulin receptor) gene plays an important role in the mucosal immunity of fish. However, not much is known about its r ...

Abstract:
... Little cherry virus 2 (LChV-2, genus Ampelovirus) is considered to be the main causal agent of the economically damaging little cherry disease, which can only be controlled by removal of infected trees. The widespread viral disease of sweet cherry (Prunus avium L.) is affecting the survival of long-standing orchards in North America and Europe, hence the dire need for an early and accurate diagnos ...

... BACKGROUND: Persistent HPV16 infection is the leading risk factor for developing cervical cancer. Anti-L1 antibodies against HPV16 produced in HPV16 infections play diverse roles in the clearance of virus infection and prevention of persistence. It has been implicated that the cervicovaginal squamous epithelial cells actually express TRIM21 and that some HPV16 particles could escape leaky endosoma ...

Abstract:
... Herpes simplex virus type-1 (HSV-1) exploits several host factors to enhance its replication and release from infected cells. It induces the production of host enzyme heparanase (HPSE) to aid in egress. While the mechanism by which HPSE assists in viral release is well-characterized, other host factors that are recruited along with HPSE for viral release are less well understood. In this study, we ...

Abstract:
... Capsid assembly pathways are strongly conserved in the complex dsDNA viruses, where major capsid proteins (MCP) self-assemble into icosahedral procapsid shells, chaperoned by a scaffolding protein. Without a scaffold, the capsid proteins aggregate and form aberrant structures. This, coupled with the rapid co-polymerization of MCP and scaffolding proteins, has thwarted characterization of the earli ...
