Hot off the presses! Work by graduate student Carlos Medina, former post-doc Koshika Yadava and the Bollyky lab is out in the journal eLife today. They report that Tr1 cells, a key regulatory cell type that promotes IL-10-based immune tolerance to potential airway allergens, do not contribute to stable tolerogenic memory. This instability may limit efforts to re-establish tolerance in asthma and other disease by expanding Tr1. Read all about it here. Congratulations!!
We’re excited to welcome Dan Liu to the lab. She is a visiting PhD student from Shanghai JiaoTong University School of Medicine, China. In our lab she will be focused on the inflammation induced by neutrophils and macrophages during chronic wound healing and the interaction of phages with bacterial infection and immune response.
Sim Low ( John Hopkins University Class of 2023) My time in the Bollyky lab was both one of the most educational and fun experiences I’ve had. Each day had a new learning opportunity and coupled with the supportive and collaborative atmosphere, the lab and its members helped me develop the skills necessary to navigating biomedical research while inspiring me to pursue further opportunities and studies. I’m so grateful to have finished my summer with insight on what it means to be a researcher along with the positive connections I’ve formed along the way.
Quynh-Lam Tran (Brown University Class of 2021) I left my summer internship at the Bollyky Lab with a renewed passion and love for research that truly confirmed the fact that the academic path I am on is the right one for me. A lot of this clarity was fueled by the engaging research and the flexibility I was allowed to explore my own questions and interests. However, I am most thankful for the chance to have spent my summer with some genuinely amazing mentors. Though I came in knowing essentially nothing, I always felt supported in my endeavors, and everyone around me always encouraged me to continue learning and exploring. Working at the Bollyky Lab was genuinely the best summer opportunity I could have hoped for, and I hope to return someday in the future!
Lab members Payton Marshall & Nadine Nagy both presented their research at the International Society for Hyaluronan Sciences meeting in Cardiff, Wales on June 12, 2019. In addition to giving well received talks, both were travel grant recipients. Congrats!
Hot off the presses – the next chapter in how filamentous phage affect bacterial infections in people. We report that Pf phage are associated with antibiotic resistance and poor outcomes in Cystic Fibrosis (CF) lung infections. These findings build on our previous report that filamentous phage serve as structural elements in biofilms and can prevent diffusion of some antibiotics (see PMID:26567508). Congratulations to Liz, Carlos Milla, and our collaborators Pat Secor, Rasmus Marvig, Helle Johansen, Elio Rossi, Søren Molin and everyone in the Bollyky Lab and the Stanford CF Center who made this happen.

Just out in Science magazine, we report that phage PROMOTE bacterial infections by triggering maladaptive anti-viral responses in human cells and suppressing anti-bacterial ones. Pf, a phage produced by the bacteria Pseudomonas aeruginosa is taken up by human cells at sites of infection and triggers TLR3 and TRIF mediated suppression of phagocytosis and TNF production. Conversely, a vaccine directed against these phage was protective against these same bacterial infections. Congratulations especially to the lead author Jolien Sweere but also Jonas Van Belleghem, Medea Popescu, Christiaan De Vries, Pat Secor, Gina Suh, Sundeep Keswani, and the rest of our lab members and collaborators who contributed to this work!

Dung, a technician in the Lab from 2018-2019, is leaving us to begin graduate school in the doctoral program in Biomedical Sciences and Engineering (PBSE) at the University of California Santa Cruz. She will be pursuing research in the Molecular, Cell and Developmental Biology (MCD) track there. Good luck Dung! We’ll miss you!
