What this research studies

This project engineers a patient’s immune cells (T cells) with tumor-targeting receptors and genetic circuits so they light up or report when they encounter dormant disseminated tumor cells (DTCs). The team will design biosensor circuits that recognize cancer-specific antigens and produce detectable signals without causing full immune attack. Work will combine lab-based testing with human-derived samples from blood and bone marrow to tune sensitivity and specificity. The goal is a tool that could one day monitor remission and catch cancer reawakening earlier than current methods.

Who could benefit from this research

Good fit: Ideal candidates would be people previously treated for estrogen receptor–positive breast cancer who are in remission but at risk for late recurrence and who can provide blood or bone marrow samples.

Not a fit: People with cancers that do not spread via dormant disseminated tumor cells, patients with widespread active metastases, or those unwilling to provide samples are unlikely to benefit from this specific approach.

Why it matters

Potential benefit: If successful, this approach could let clinicians detect dormant cancer cells earlier, enabling closer monitoring or preventive treatment before metastatic relapse.

How similar studies have performed: Engineered T cells (like CAR‑T) have produced major successes in some blood cancers, but using T cells as biosensors to detect dormant solid‑tumor cells is largely novel and experimental.
