Journal ArticleDOI
Broad, Intense Anti-Human Immunodeficiency Virus (HIV) Ex Vivo CD8+ Responses in HIV Type 1-Infected Patients: Comparison with Anti-Epstein-Barr Virus Responses and Changes during Antiretroviral Therapy
Marc Dalod,Marion Dupuis,Jean-Christophe Deschemin,D. Sicard,Dominique Salmon,Jean-François Delfraissy,Alain Venet,Martine Sinet,Jean-Gérard Guillet +8 more
TL;DR: The findings suggest that the CD8+ hyperlymphocytosis commonly observed in HIV infection is driven mainly by virus replication, through intense, continuous activation of HIV-specificCD8+ T cells until ultimate progression toward disease.
Journal ArticleDOI
Weak anti-HIV CD8+ T-cell effector activity in HIV primary infection
Marc Dalod,Marion Dupuis,Jean-Christophe Deschemin,Cécile Goujard,Christiane Deveau,Laurence Meyer,Nicole Ngo,Christine Rouzioux,Jean-Gérard Guillet,Jean-François Delfraissy,Martine Sinet,Alain Venet +11 more
TL;DR: The weakness of the immune response during HIV PI could partially account for the failure to control HIV and have potential importance for defining immunotherapeutic strategies and establishing the goals for effective vaccination.
Journal ArticleDOI
Glutathione provides a source of cysteine essential for intracellular multiplication of Francisella tularensis.
Khaled Alkhuder,Karin L. Meibom,Karin L. Meibom,Iharilalao Dubail,Iharilalao Dubail,Marion Dupuis,Marion Dupuis,Alain Charbit,Alain Charbit +8 more
TL;DR: Evidence is presented that the capacity this intracellular bacterial pathogen has evolved to utilize the available GSH, as a source of cysteine in the host cytosol, constitutes a paradigm of bacteria–host adaptation.
Journal ArticleDOI
Hfq, a novel pleiotropic regulator of virulence-associated genes in Francisella tularensis.
Karin L. Meibom,Karin L. Meibom,Anna-Lena Forslund,Anna-Lena Forslund,Kerstin Kuoppa,Khaled Alkhuder,Khaled Alkhuder,Iharilalao Dubail,Iharilalao Dubail,Marion Dupuis,Marion Dupuis,Åke Forsberg,Åke Forsberg,Alain Charbit,Alain Charbit +14 more
TL;DR: It is demonstrated that Hfq promotes resistance to several cellular stresses and appears to be a new pleiotropic regulator of virulence in F. tularensis, acting mostly as a repressor, in contrast to the other regulators identified so far.
Journal ArticleDOI
The heat‐shock protein ClpB of Francisella tularensis is involved in stress tolerance and is required for multiplication in target organs of infected mice
Karin L. Meibom,Karin L. Meibom,Iharilalao Dubail,Iharilalao Dubail,Marion Dupuis,Marion Dupuis,Monique Barel,Monique Barel,Juraj Lenčo,Jiri Stulik,Igor Golovliov,Anders Sjöstedt,Alain Charbit,Alain Charbit +13 more
TL;DR: It is demonstrated here that ClpB of F. tularensis live vaccine strain (LVS) is important for resistance to cellular stress and promoter analysis shows that the transcriptional start is preceded by a σ32‐like promoter sequence and expression of clpB is induced by heat shock, indicating that expression of ClpP is dependent on the heat‐shock response mediated by ρ32, the only alternative σ‐factor present in Francisella.
