During my sophomore year of college, the background on my computer screen was a cystic fibrosis transmembrane conductance regulator (CFTR) protein, specifically a visualization of its quaternary structure. It looked something like this image. The simplified graphic isn’t an exact representation of what the CFTR protein looks…
Mutations & Conversations
— Tré LaRosa

Tré LaRosa is a scientific project manager, patient advocate, and writer. He has cystic fibrosis (CF) and carries two copies of the F508del mutation. He’s been on Trikafta since 2019. He writes about science, living with CF, grief, family, and everything in between in an effort to get you thinking about what it means to be human. He lives in Arlington, Virginia with his fiancée Jessica and their two wonderful, lazy dogs, Duncan and Leo. He enjoys playing sports, being outdoors, and reading — and especially buying more books.
Over the years, I’ve spent a lot of time on the phone with various organizations involved in my healthcare. Probably the most frustrating thing is having to cycle from one person to another, who then directs me back to the first person I talked to. It seems like it’s only…

In high school, I aspired to be a pulmonologist for obvious reasons: I wanted to aid the CF community by directly helping patients. It seemed logical. I dreamed of becoming a pulmonologist because my CF doctors had been some of my greatest role models. They were quite literally…
My Family Had 2 Children with CF
It was unlikely that my parents would bear two children with CF. When both parents carry a CF mutation but don’t have the disease itself, there is a 1 in 4 chance that a child will have CF. To determine the likelihood of two events independent of one…
My Thoughts on Exercise and CF
It’s hard to understate the benefits of exercise for healthy people, let alone people with CF. According to the Mayo Clinic, some of these benefits include: It controls weight. It combats health conditions and diseases. It improves mood. It boosts energy. It promotes better sleep. All of these…
A couple of months ago, I did back-of-the-envelope calculations on basic CF stats. Here’s what I asked: In a year, how much time do I spend doing treatments? How many pills do I take? As I wrote last week, the spectrum of CF presentation is about as…
If you’ve ever met more than one person with cystic fibrosis, it’s likely they had very different experiences than you. First, their approach likely will be different; chronic disease affects everyone differently mentally, so some are vocal and “embrace” it, while others are quieter and choose to consider it a…
I ecstatically joined Cystic Fibrosis News Today in September because it was my first major opportunity to generate CF discussion. In this column, I’ve written about what a cure might actually mean for the community, why it’s important for parents to empower their children with CF, the…
One of my earliest memories from elementary school was leaving class a little early before lunch to go to the nurse’s office to take my enzymes, always accompanied by a school peer. I wasn’t allowed to bring my enzymes with me to school because entrusting a young kid to take…
When Serena Lawrence, the late Bionews senior columns editor, responded to my email about potentially writing for Cystic Fibrosis News Today and promptly offered me a columnist position, I was awestruck. This was the first concrete (read: monetary) endorsement of my writing. My hope with this column was to…
If you keep up with CF research, you may have seen the news about Phase 3 of the triple combination Vertex therapies. In these results, patients had a robust lung function boost after trialing a triple combination therapy treatment. More importantly, these results were tested in a broad population…
The period between Halloween and New Year’s — what I usually call “the Holidays” — is the time of year I’ve always most enjoyed. Christmas music, chilly weather, early evenings, annual reunions with family — all of that made waking up each day my absolute favorite. I would reflect on…
As I’ve grown older, I’ve become a self-advocate, taking initiative when possible. I’ve developed a close relationship with my care team, which I believe is crucial for adults with CF who want to become authorities on their care. I took a sociology class in college on healthcare ethics. We…
