Diving into bacterial dormancy: emergence of osmotically stable wall-less forms in an aquatic environment

F. Carvalho, A. Carreaux, A. Sartori-Rupp, S. Tachon, A. D. Gazi, P. Courtin, P. Nicolas, F. Dubois-Brissonnet, A. Barbotin, E. Desgranges, K. Gloux, C. Schouler, R. Carballido-Lopez, M.-P. Chapot-Chartier, E. Milohanic, , A. Pagliuso

This study identifies osmotically stable wall-less forms in Listeria monocytogenes during starvation, revealing a conserved stress response mechanism across Listeria species.

Structure-Function analysis of Lactiplantibacillus plantarum DltE reveals D-alanylated lipoteichoic acids as direct symbiotic cues supporting Drosophila juvenile growth

N. Nikolopoulos, R. C. Matos, S. Ravaud, P. Courtin, H. Akherraz, S. Palussiere, V. Gueguen-Chaignon, M. Salomon-Mallet, A. Guillot, Y. Guerardel, M.-P. Chapot-Chartier, C. Grangeasse, F. Leulier

The paper identifies D-Ala-LTAs as symbiotic cues that support Drosophila juvenile growth by promoting intestinal peptidase expression through the action of DltE.

Ser/Thr kinase-dependent phosphorylation of the peptidoglycan hydrolase CwlA controls its export and modulates cell division in Clostridioides difficile

T. Garcia-Garcia, S. Poncet, E. Cuenot, T. Douche, Q. Giai Gianetto, J. PELTIER, P. Courtin, M.-P. Chapot-Chartier, M. Matondo, B. Dupuy, T. Candela, I. Martin-Verstraete

This study identifies CwlA as a substrate of the STK PrkC in C. difficile, showing that phosphorylation regulates its export and modulates cell division by controlling peptidoglycan hydrolysis.

D-alanylation of Teichoic Acids in Bacilli impedes the immune sensing of peptidoglycan in Drosophila

Z. Attieh, M. Kallassy, A. Rejasse, P. Courtin, I. Gomberts Boneca, M.-P. Chapot-Chartier, V. Sanchis Borja, L. El Chamy

The paper shows that D-alanylation of teichoic acids in Bacillus thuringiensis and Lactobacillus plantarum reduces immune sensing of peptidoglycan in Drosophila by limiting its release and activation of the IMD-NF-κB pathway.

D-Alanine esterification of teichoic acids contributes to Lactobacillus plantarum mediated intestinal peptidase expression and Drosophila growth promotion upon chronic undernutrition

R. C. Matos, H. Gervais, P. Joncour, M. Schwarzer, B. Gillet, M. E. Martino, P. Courtin, S. Hughes, M.-P. Chapot-Chartier, F. Leulier

This study identifies the pbpX2-dlt operon in Lactobacillus plantarum as critical for D-alanine esterification of teichoic acids, which enhances intestinal peptidase expression and promotes Drosophila growth under chronic undernutrition.
