Published: December 2010

A novel QD-peptide complex for detecting HIV-1 protease activity was prepared from simple one step electrostatic interaction. Fluorescence recovery of the pre-quenched QD through fluorescence resonance energy transfer allowed for in vitro assay and live cell imaging of the protease activity in HIV-1 transfected cells, proving the potential for cell-based protease inhibitor screening.

Increasing evidence suggests that inhibition of receptor-interacting serine/threonine-protein kinase (RIPK) 1/RIPK3/mixed lineage kinase domain-like pseudokinase (MLKL) necrosome has protective effects in vivo models of painful conditions seen in humans associated with inflammation and demyelination in the central nervous system. However, the contribution of RIPK1-driven necroptosis to inflammatory pain remains unknown. Therefore, this study aims to determine the effect of necrostatin (Nec) -1s, a selective RIPK1 inhibitor, on lipopolysaccharide (LPS)-induced inflammatory pain and related underlying mechanisms.

Chronic Obstructive Pulmonary Disease (COPD) is a poorly reversible respiratory disorder distinguished by dyspnea, cough, expectoration and exacerbations due to abnormality of airways or emphysema. In this review, we consider the therapeutic potential of targeting Mammalian target of Rapamycin (mTOR) for treating COPD. The mTOR is a highly conserved serine-threonine protein kinase that integrates signals from growth factors and nutrients to control protein synthesis, lipid biogenesis and metabolism.

Mice with Reduced PAR4 Reactivity show Decreased Venous Thrombosis and Platelet Procoagulant Activity.

Background: Hypercoagulation and thrombin generation are major risk factors for venous thrombosis. Sustained thrombin signaling through PAR4 promotes platelet activation, phosphatidylserine exposure, and subsequent thrombin generation. A single-nucleotide polymorphism in PAR4 (rs2227376) changes proline to leucine extracellular loop 3 (P310L), which decreases PAR4 reactivity and is associated with a lower risk for venous thromboembolism (VTE) in a GWAS meta-analysis.

The viral serpin SPI-1 directly inhibits the host cell serine protease FAM111A.

Electronic address:

The host-range mutant of rabbitpox virus (RPXV) with a deletion in the gene encoding the serpin serine protease inhibitor 1 (SPI-1) fails to replicate efficiently in restrictive host cells. Depletion of the host cell serine protease FAM111A restores viral replication in these cells, suggesting that SPI-1 targets FAM111A to facilitate infection. However, direct evidence of SPI-1 inhibiting FAM111A has been lacking.

Duck viral hepatitis (DVH) caused by duck hepatitis A virus (DHAV) is a highly contagious and economically important disease of ducklings worldwide. In many parts of the globe, disease outbreaks are reported in spite of vaccinations, probably due to antigenic diversity among DHAV genotypes. We previously reported the first isolation of DHAV-2 (Genotype -2) from ducklings in Tamil Nadu, India.
