This project is a part of the international Infect-Era program, AMOEBAC: Entamoeba histolytica-bacterium interaction and the role of this interaction in intestinal pathogenesis (http://www.infect-era.eu/2nd-call-2014) The aim of this investigation is to understand the induced […]

Entamoeba histolytica is a protozoan parasite and an amitochondriate pathogenic amoeba, which may cause dysentery and liver abscess in humans (i.e. amoebiasis). Differential pathogenicity is observed among E. histolytica strains: strain HM1:IMSS is virulent […]

 Cryptococcus neoformans is a sugar-coated yeast that is able to interact closely with numerous organisms in the environment including amebae, paramecium of nematodes. The interaction with these organisms probably shaped its virulence. The ability […]

Mycobacterium abscessus (M. abs) is an emerging pathogen causing lung infections in cystic fibrosis patients. Although the environmental reservoir of M. abs is currently unknown, M. abs possesses a gene pool dedicated to a […]

Vertebrate adult neural stem cells (NSCs) are generally quiescent, and the frequency of their cell cycle re-entry (“activation”) conditions their lifespan. Little is known of the molecular pathways controlling the NSC quiescence/activation balance. We […]

“The thymus is a specialized organ that provides a unique environment for T cell development and differentiation. The study the thymus-settling progenitors (TSPs) and how they differentiate is important for the characterization of the […]

Germinal centers (GC) are essential for an effective humoral immune response. The GC provides an environment that stimulates B cells to proliferate in response to antigens and accumulate somatic mutations in immunoglobulin (Ig) genes, […]

OmrA and OmrB are two small regulatory RNAs (sRNAs) conserved in enterobacteria. Their transcription is activated by the EnvZ-OmpR two-component system and their levels therefore increase in response to an increase in osmolarity. They […]

Overproduction of membrane proteins in the E. coli strains generally induce cell death. The multiple mutant C43 (DE3) derivative of BL21 (DE3) strain was selected to resist this overproduction. In this mutant,  the membrane […]

Cassandre is a project of personal database system, integrating a “user-friendly” interface to manage and explore multiple sets of large-scale experimental results in biology. Large-scale experiments that generate quantitative data, such as changes in […]

The pathogenesis of HIV infection, and in particular the development of immunodeficiency, remains incompletely understood. During HIV infection both innate and adaptive immune responses are raised, but they appear to be insufficient or too […]

Rabies is an untreatable disease of humans due to lyssaviruses and Rabies virus (RABV) in particular. RABV is a highly neurotropic virus which prevent inflammation during the early phase of infection. In the brain, […]

The three HP1 (Heterochromatin Protein 1), HP1a, HP1b, and HP1g proteins are epigenetic markers of heterochromatin, the condensed, repressed form of chromatin. They are typically known to associate to the di-/tri-methylated lysine 9 of […]

The platform provides statistical analyses of RNA-seq count data. Before any project starts,  we help the user to design his experiment in order to ensure that it really addresses the biological question he wishes […]

The platform also has important technological and bibliographical survey activities for the wet lab as well as for the dry lab. Over the last months, the platform has established methods for the transcriptome sequencing […]

Il est aujourd’hui connu que les protéines ribosomiques ont des fonctions extra-ribosomiques, et qu’en particulier, certaines d’entre elles contrôlent la transcription. Nous avons montré que, chez la drosophile, RPL12 interagit avec le facteur épigénétique […]

SARTools is a R package dedicated to the differential analysis of RNA-seq data. It provides tools to generate descriptive and diagnostic graphs, to run the differential analysis with one of the well known DESeq2 […]
