A simplified model of the binding interaction between stromal cell-derived factor-1 chemokine and CXC chemokine receptor 4.

abstract：:Hepatitis C virus (HCV) triggers coordinated innate and adaptive response in host cell. HCV genome and proteins of the replicating virus are recognized as non-self-antigens by host cell to activate Toll Like Receptors (TLRs). Activated TLRs ultimately express cytokines, which can clear virus either by activating inter...

abstract：:Many polyketides show biological activities and have thus been applied in clinics, as food additives, and in agriculture. Type II thioesterases (TEIIs) play an important role in polyketide biosynthesis. Most TEIIs belong to α/β-hydrolase family and usually contain a catalytic triad Ser-His-Asp. In polyketide biosynthe...
