MAMPS identification through modulation of AP1, PPAR-gamma & other NF using metagenomics

For this research project, Mrs Malgorzata NEPELSKA has been recruited.

Main supervisor

INRA (H. Blottière)


Karolinska Institute (S. Pettersson)

Duration : 36 months 

Start date : end of 2008/beginning of 2009

Objective. Identification of new bacterial molecules involved in the cross-talk with host intestinal epithelial cells and signaling pathways involved.

Approach. Screening of metagenomics libraries for clones modulating transcription pathways using reporter gene technology. Analysis of potential receptor involved and signaling pathways using cutting edge cell signaling technology.
