About Our Research

How does the innate immune system fight off infections using ‘non-professional’ immune cells? In the Troemel lab, we address this question by studying the dynamic between the nematode C. elegans and two of its naturally occurring intestinal pathogens— the fungal, spore-forming microsporidium Nematocida parisii, and the positive-sense, single-stranded RNA Orsay virus. See the research tab for more information.

The Troemel Lab was established in La Jolla at the University of California San Diego in the fall of 2008. Click on the publications tab to learn more about our latest pursuits!

Featured Publication

Tecle E, Chhan CB, Franklin L, Underwood RS, Hanna-Rose W, Troemel ER (2021). The purine nucleoside phosphorylase pnp-1 regulates epithelial cell resistance to infection in C. elegans.

Congratulations to Project Scientist Eillen Tecle on her latest publication discussing pnp-1‘s role in C. elegans immunity! We’d also like to celebrate Troemel lab tech Crystal Chhan’s contributions and second authorship on the project. We commemorated the success with a publication potluck.

23rd International C. elegans Conference

C. elegans 2021 Conference Opening Plenary Talk

Tune in to the opening plenary session of the Genetic Society of America’s 23rd International C. elegans Conference, which includes a opening session talk from UC San Diego’s Emily Troemel.
 
This session— chaired by Barbara Conradt (University College London, UK) and Piali Sengupta (Brandeis University, USA)— features talks that discuss topics of interest in C. elegans research. Emily’s talk on host/pathogen interactions, Worm Health Organization: Understanding the Pandemics Facing C. elegans, is featured here.

Global Immunotalks: Characterization of the Intracellular Pathogen Response in C. elegans

Exploring innate immunity in C. elegans with Emily Troemel

Global Immunotalks is a presentation series organized by Carla V. Rothlin and Elina I. Zúñiga that explores a variety of immunology-related topics. Started back in April, these talks are hosted via zoom every Wednesday at 9 AM, with videos of presentations uploaded to YouTube for later viewing.
 
In the featured video, our own Emily Troemel gives an introduction to C. elegans innate immunity, and shares some of the exciting research that our lab continues to explore!

UCSD Round Table: COVID-19

A Deep Look into the Biology and Evolution of SARS-CoV-2, Causative Agent of COVID-19

Join our own Emily Troemel and other UC San Diego infectious disease researchers as they provide an overview of the biology and evolution of the SARS-CoV-2 virus.
 
In the featured roundtable, they share their expertise in the dynamics of host-pathogen interactions and viral life-cycles and how they relate to this global challenge. Click below to see the second installment— Vaccines, Drugs, and the Evolutionary Arms Race— as well as other COVID-19 related videos.
A silver lining in the dark cloud of COVID-19

While it is true that the ongoing pandemic has necessitated a transition to work from home in order to minimize the spread of SARS-CoV-2, we are taking advantage of virtual communications to strengthen the ties to
our collaborators. We are currently hosting joint weekly lab meetings across states and continents, uniting scientific minds in one zoom room to facilitate the flow of ideas!
