Bidirectional transport in cilia is carried out by polymers of the IFTA and IFTB protein complexes, referred to as anterograde and retrograde IFT “trains”. Anterograde trains deliver cargoes from the cell to the ciliary tip, then remodel into retrograde trains for cargo export. We set out to underst...

The retrograde transport inhibitor Retro-2 has a protective effect on cells and in mice against Shiga-like toxins and ricin. Retro-2 causes toxin accumulation in early endosomes, and the relocalization of the Golgi SNARE protein syntaxin-5 to the endoplasmic reticulum. The molecular mechanisms by wh...
Retrograde response was widely studied in budding yeast but the main transcription factors that transmit it (RTG1,2 and 3) are not conserved in other organisms, thus it is interesting to study how communication between mitochondria and nucleus evolved in distantly related fission yeast, and which ar...
We recently demonstrated that colistin resistance in Acinetobacter baumannii can result from mutational inactivation of genes essential for lipid A biosynthesis. Consequently, strains harboring these mutations are unable to produce the major Gram negative bacterial surface component, lipopolysacchar...
