Excited to share our latest from Surya Dev Aggarwal, now on biorxiv! We describe the unexpected role of BlpC in driving intra-strain competitive success, with physiological consequences on ecology of the colonizing strain and importantly, transmission to new hosts! Tweetorial below.

Congratulations to graduate student Sheya Sheya Ma for passing her qualifying examination and becoming a PhD candidate. Looking forward to all the discoveries she’ll make in the lab.

Pleased to share some of our latest work available online now in Cell Host & Microbe. In this work, we discovered that quorum sensing induced bacteriocins mediate intra-strain competition in pneumococcus during colonization and transmission. authors.elsevier.com/c/1g5cb6t8JEjA…

A selfish program reduces S. pneumoniae diversity. Intra-strain competition upon #Spneumoniae colonization causes loss of clonal diversity. Bacteriocins induced by BlpC led to predation of kin & tightening of population bottlenecks Surya Dev Aggarwal Weiser Lab @ NYU Langone Health cell.com/cell-host-micr…

A selfish bacteriocin dictates pneumococcal domination:Trappetti/Paton discuss Surya Dev Aggarwal Weiser Lab @ NYU Langone Health work on population dynamics of S.pneumoniae colonization. Bacteriocin promotes survival of lineages, providing population bottleneck & limiting diversity cell.com/cell-host-micr…

Happy to share our latest work from Gavyn Bee that was published in Immunity earlier today!! Here is a tweetorial summarizing the major findings from this work.

Excited to see Gavyn Gavyn Bee from Weiser Lab @ NYU Langone Health NYU Langone Health defend his thesis defense. starting now! Brilliant and touching intro from Jeff! here we go!

Congratulations to our newly minted PhD - Dr. Bee (Gavyn Bee) did a fantastic job showcasing his research in the lab over the past 6 years! Well done 🎉🎊🍾

Is phenotypic variation functional? Stoked about our latest preprint spearheaded by the amazing Anne-Stephanie DMF UNIL Université de Lausanne in collaboration with a fantastic team of people @vrrenske Surya Dev Aggarwal Javier Santos Moreno @LalouxLab Yolanda Schaerli Weiser Lab @ NYU Langone Health biorxiv.org/content/10.110…

I’m biased, but this is such a cool paper and very happy that it’s now published Nature Communications 😀Congratulations to Anne-Stéphanie @vrrenske Surya Dev Aggarwal Weiser Lab @ NYU Langone Health @LalouxLab Javier Santos Moreno Yolanda Schaerli! nature.com/articles/s4146…

Why are infants susceptible to invasive pneumococcal diseases? Excited to share our latest work led by Kristen Lokken-Toyli which explores this question and elucidates the age-dependent mechanisms that drive pneumococcal spread from the mucosa. PLOS Pathogens journals.plos.org/plospathogens/…

🚨Excited to share our new study below!🚨 1/7: Childhood mortality from bacterial respiratory & enteric pathogens remains a global concern. But what compromises infants' ability to fight infections? Our study delves into the immune deficiencies intrinsic to early age.

Excited to share our latest work studying pneumococcal pneumonia. We found that pneumococcal population structures undergo massive changes within the lung. This bacteriocin-mediated turnover of the population "promotes" pneumococcal pneumonia nature.com/articles/s4200…

Profiling of pneumococcal population structure during infection reveals an unappreciated role of bacteriocins in driving the development of pneumonia by facilitating the release of inflammatory mediators nature.com/articles/s4200…
