🧠 Does age change how we fight brain cancer?
New insights on immunotherapy & glioblastoma
🔥 Hot off the press!
Our latest study in takes on a critical—and often overlooked—question in glioblastoma (GBM):
👉 What happens when immunotherapy meets the aging immune system?
🧬 Why this matters
Immunotherapy works by training your own immune system to attack cancer.
But as we age, our immune system changes (immunosenescence). GBM is more common in older adults—yet most clinical trials focus on younger patients.
🤔 The big question
Does immunotherapy work the same way across ages?
🔍 What we found
By analyzing data across multiple studies (a meta-analysis), we discovered that an aging immune system creates a different tumor environment—one that can make it harder for current immunotherapies to fully activate immune cells.
💡 The takeaway
Immunotherapy isn’t failing older patients—but a one-size-fits-all approach may be. Different immune ages may need different strategies.
🚀 Looking ahead
This is a call to design smarter, age-aware clinical trials—so breakthroughs benefit everyone, not just the young.
🧠 To beat brain cancer, we must treat the tumor and the person it’s in.
Personalized care starts with understanding the immune system—at every age. 💪🧬
👏 Huge congratulations to all the co-authors!

Immunotherapy has yet to meaningfully translate to more complex solid tumors, such as Glioblastoma (GBM), which is a disease of old age with a median diagn

🧠🧬 We can read thousands of genes in a single cell…
but still struggle to explain what that cell actually is.
That gap is now one of the biggest barriers to turning data into patient care.
So we built CASSIA.
CASSIA is an AI system that works more like a clinical team than a black box.
Multiple AI agents analyze cell data, challenge each other, and—most importantly—explain their decisions.
Why this matters ⬇️
In cancer, immunotherapy, and neuro-oncology, identifying therapy-resistant tumor cells or critical immune populations can change how we:
• design treatments
• predict recurrence
• move discoveries toward patients
AI that’s accurate but not interpretable isn’t enough.
Our goal isn’t to replace scientists and clinicians. It is to scale expertise, reduce bias, and make single-cell biology usable—not mysterious.
🔬 If AI is going to belong in medicine, it must be transparent and trustworthy.
We believe CASSIA is a step in that direction. What would make you trust AI in clinical decision-making?

Assigning cell types in single-cell RNA-seq is essential yet challenging, as it requires expertise, time, and is often subjective. Here, the authors present CASSIA, a multi-agent AI system that provides automated, interpretable, and quality-controlled annotations with high accuracy.

One of my founding missions for establishing Dey Lab was to cultivate, inspire and empower next generation of physicians, surgeons and scientists. I am proud to say that all members of Dey lab take this mission very seriously and we create a graduated pipeline of mentorship and success. So, when I get a letter like this, it really makes my heart sing and makes me feel like a proud parent!!!
🌟 Huge shoutout to Jack Shireman (My graduate Student) for his incredible dedication to the UWCCC ARISE (Advancing Research in Science with Excellence) program over the past several summers!
Through his mentorship in the Dey Lab, Jack has inspired high school interns and undergraduate students by:
🔬 Introducing them to brain cancer research
🤝 Creating a welcoming, supportive environment
💡 Building their confidence and skills in the lab
📈 Guiding them to take ownership of science and their projects
Right before my eyes Jack is growing up to be an excellent scientist and also a role model whose passion, patience, and encouragement empower the next generation of scientists. Future of science is bright!!!

On Glioblastoma Awareness Day, let's talk about why awareness is so crucial.

We at Dey Lab work hard EVERYDAY with one goal: finding a cure for GBM. However, Glioblastoma is a formidable opponent and every bit of awareness fuels the fight.
Your understanding and support directly contribute to:
Accelerating our vital research for new therapies.
Empowering advocacy for better patient care.
Shining a light on an urgent unmet medical need.

Together, we can make a difference in the lives of those battling GBM.

Excited to share a very timely sneak peek at our recent work on developing organoid based brain tumor models with scalable neural organoid system developed by Stem Pharm. In the context of recent NIH guidelines for limiting animal testing and focusing more on human disease model, our work clearly shows the importance of this type of high-throughput, scalable organoid model’s role in disease modeling and drug testing.
Congratulations to all the co-authors for their hard work on this very important project!!!
