Visualizing HIV-1 assembly.
The assembly of an HIV-1 particle is a complex, multistep process involving several viral and cellular proteins, RNAs and lipids. While many macroscopic and fixed-cell microscopic techniques have provided important insights into the structure of HIV-1 particles and the mechanisms by which they assemble, analysis of individual particles and their assembly in living cells offers the potential of ...
متن کاملSNAREs in HIV-1 assembly
Viruses have a limited number of genes but a complex life cycle and have evolved to utilize numerous host factors to complete their replication. The assembly and budding process of enveloped viruses utilizes numerous cellular factors to facilitate transport from one membrane bound compartment to the other. The host SNARE proteins are widely involved in late stages of vesicular mediated transpor...
متن کاملHIV-1 assembly, budding, and maturation.
A defining property of retroviruses is their ability to assemble into particles that can leave producer cells and spread infection to susceptible cells and hosts. Virion morphogenesis can be divided into three stages: assembly, wherein the virion is created and essential components are packaged; budding, wherein the virion crosses the plasma membrane and obtains its lipid envelope; and maturati...
متن کاملIntegrating the HIV-1 assembly/maturation pathway.
In PNAS, Jurado et al. (1) describe an unexpected mechanism of action of a new class of HIV type 1 (HIV-1) integrase (IN) inhibitors. Several years ago it was discovered that the HIV-1 IN was targeted to sites in chromatin by the host protein lens epithelium-derived growth factor (LEDGF)/p75 (2). The site of interaction between IN and LEDGF/p75 was defined, and inhibitors to block that interact...
متن کاملDynamics of HIV-1 Assembly and Release
Assembly and release of human immunodeficiency virus (HIV) occur at the plasma membrane of infected cells and are driven by the Gag polyprotein. Previous studies analyzed viral morphogenesis using biochemical methods and static images, while dynamic and kinetic information has been lacking until very recently. Using a combination of wide-field and total internal reflection fluorescence microsco...
