Abstract
Enteroviral replication reorganizes the cellular membrane. Upon infection, viral proteins and hijacked host factors generate unique structures called replication organelles (ROs) to replicate their viral genomes. ROs promote efficient viral genome replication, coordinate the steps of the viral replication cycle, and protect viral RNA from host immune responses. More recent researches have focused on the ultrastructure structures, formation mechanism, and functions in the virus life cycle of ROs. Dynamic model of enterovirus ROs structure is proposed, and the secretory pathway, the autophagy pathway, and lipid metabolism are found to be associated in the formation of ROs. With deeper understanding of ROs, some compounds have been found to show inhibitory effects on viral replication by targeting key proteins in the process of ROs formation. Here, we review the recent findings concerning the role, morphology, biogenesis, formation mechanism, and inhibitors of enterovirus ROs.

A large scale high-throughput screen identifies chemical inhibitors of phosphatidylinositol 4-kinase type II alpha. J Lipid Res 2019; 60:683-693. [PMID: 30626625 DOI: 10.1194/jlr.d090159] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2018] [Revised: 01/08/2019] [Indexed: 12/24/2022] Open
Abstract
The minor phospholipid, phosphatidylinositol 4-phosphate (PI4P), is emerging as a key regulator of lipid transfer in ER-membrane contact sites. Four different phosphatidylinositol 4-kinase (PI4K) enzymes generate PI4P in different membrane compartments supporting distinct cellular processes, many of which are crucial for the maintenance of cellular integrity but also hijacked by intracellular pathogens. While type III PI4Ks have been targeted by small molecular inhibitors, thus helping decipher their importance in cellular physiology, no inhibitors are available for the type II PI4Ks, which hinders investigations into their cellular functions. Here, we describe the identification of small molecular inhibitors of PI4K type II alpha (PI4K2A) by implementing a large scale small molecule high-throughput screening. A novel assay was developed that allows testing of selected inhibitors against PI4K2A in intact cells using a bioluminescence resonance energy transfer approach adapted to plate readers. The compounds disclosed here will pave the way to the optimization of PI4K2A inhibitors that can be used in cellular and animal studies to better understand the role of this enzyme in both normal and pathological states.

Abstract
Enterovirus 71 (EV71) is a human pathogen that causes hand, foot, mouth disease and neurological complications. Although EV71, as well as other enteroviruses, initiates a remodeling of intracellular membrane for genomic replication, the regulatory mechanism remains elusive. By screening human cDNA library, we uncover that the Golgi resident protein acyl-coenzyme A binding domain-containing 3 (ACBD3) serves as a target of the 3A protein of EV71. This interaction occurs in cells expressing 3A or infected with EV71. Genetic inhibition or deletion of ACBD3 drastically impairs viral RNA replication and plaque formation. Such defects are corrected upon restoration of ACBD3. In infected cells, EV71 3A redirects ACBD3, to the replication sites. I44A or H54Y substitution in 3A interrupts the binding to ACBD3. As such, viral replication is impeded. These results reveal a mechanism of EV71 replication that involves host ACBD3 for viral replication.
