Protamines are a group of highly basic proteins first discovered in spermatozoon that allow for denser packaging of DNA than histones and will result in down-regulation of gene transcription[1]. It is well recognized that the Autographa californica multicapsid nucleopolyhedrovirus (AcMNPV) encodes ..., Abstract

Naturally occurring mutations in surface proteins of Hepatitis B virus (HBV) usually result in altered hepatitis B surface antigen (HBsAg) secretion efficiency. In the present study, we reported two conserved residues, M75 and M103 with respect to HBsAg, mutations of which not only attenuated HBsAg ..., Abstract

Abstract: Fibroblast growth factor (FGF) is a key regulator of developmental processes. A FGF homolog (vFGF) is found in all lepidopteran baculoviruses. Autographa californica nucleopolyhedrovirus (AcMNPV) and Bombyx mori NPV (BmNPV) vFGFs are chemotactic factors. Here we analyzed the vfgf of ..., Abstract

Baculoviruses produce two viral phenotypes, the budded virus (BV) and the occlusion-derived virus (ODV). ODVs are released from occlusion bodies in the midgut where they initiate a primary infection. Due to the lack of an in vitro system, the molecular mechanism of ODV infection is still unclear. ..., Abstract

Baculovirus has many advantages as vectors for gene transfer. We demonstrated that recombinant baculovirus vectors expressing p35 (Ac-CMV-p35) and eGFP (Ac-CMV-GFP) could be transduced into human kidney 293 cells efficiently. The level of transgene expression was viral dose dependent and high-level ..., Abstract
