How CD8 T cells use tiny forces to recognize infected cells

Ligand-Dependent [alpha][beta]TCR Function

NIH-funded research Dana-Farber Cancer Inst · NIH-11253691

Researchers look at how a type of immune cell (CD8 T cells) uses very small mechanical forces to find virus-infected cells, which could help people with flu and other infections.

What this research studies

This project pairs precision physics tools with cell and tissue analysis to see how individual T cell receptors behave when they bind targets. Scientists will use optical tweezers and single-molecule measurements alongside single-cell RNA sequencing and paired TCR sequencing to study influenza-specific CD8 T cells in lymph nodes and lungs. They will compare high-performing T cells that detect very few target molecules to others to learn what features make T cells sensitive and long-lived. The goal is to link molecular and structural behavior of TCRs to how T cells act in real tissues.

Who could benefit from this research

Good fit: People who have had influenza or healthy volunteers willing to donate blood or tissue samples for studying influenza-specific CD8 T cells would be most relevant for participation.

Not a fit: Patients seeking immediate clinical treatment or those with conditions unrelated to T cell immunity are unlikely to receive direct benefit from this basic research.

Why it matters

Potential benefit: If successful, the work could inform vaccines or T cell therapies that make immune cells detect infections or tumors more reliably.

How similar studies have performed: Prior single-molecule and TCR sequencing studies have revealed important principles of T cell recognition, but combining optical tweezers with spatial transcriptomics in tissues is relatively novel.
