Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Polymer therapeutics is a class of (bio)hybrid materials that include a plethora of biologically active (synthetic) macromolecules that either consist of polymeric drugs, drug-polymer conjugates, peptide/protein-polymer conjugates or of drug, peptide or pr ...
HIV-1 infected macrophages play an important role in rendering resting T cells permissive for infection, in spreading HIV-1 to T cells, and in the pathogenesis of AIDS dementia. During highly active anti-retroviral treatment (HAART), macrophages keep produ ...
Molecular fusions of CD4, the receptor for human immunodeficiency virus (HIV), with immunoglobulin (termed CD4 immunoadhesins) possess both the gp120-binding and HIV-blocking properties of recombinant soluble CD4, and certain properties of IgG, notably lon ...
A genome-wide screen for large structural variants showed that a copy number variant (CNV) in the region encoding killer cell immunoglobulin-like receptors (KIR) associates with HIV-1 control as measured by plasma viral load at set point in individuals of ...
Peptides derived from the HR1 or HR2 regions of the HIV-1 envelope glycoprotein gp41 have been shown to be effective inhibitors to prevent virus-host cell membrane fusion. These peptide drugs, however, suffer from relatively short plasma half-lives and are ...
As a neurotropic virus, human immunodeficiency virus type 1 (HIV-1) invades the brain and causes severe neuronal, astrocyte, and myelin damage in AIDS patients. To gain access to the brain, HIV-1 must migrate through brain microvascular endothelial cells ( ...
Isolated primary human cells from different donors vary in their permissiveness-the ability of cells to be infected and sustain the replication of human immunodeficiency virus type 1 (HIV-1). We used replicating HIV-1 and single-cycle lentivirus vectors in ...
The membrane of human immunodeficiency virus type 1 (HIV-1) virions contains high levels of cholesterol and sphingomyelin, an enrichment that is explained by the preferential budding of the virus through raft microdomains of the plasma membrane. Upon deple ...
Over the course of evolution, retroviruses and their hosts have been in constant conflict, resulting in a long-term evolutionary "arms race" in which host and pathogen alternately gain selective advantages through functional innovations. On the host side, ...
BACKGROUND: CD4+ T lymphocytes are the primary targets of HIV1 but cannot be infected when fully quiescent, due to a post-entry block preventing the completion of reverse transcription. Chiu et al. recently proposed that this restriction reflects the actio ...
