T cells, the immune cells that hunt infected and cancerous cells, must tell real threats apart from the body's own healthy molecules. Their main sensor is the T cell antigen receptor (TCR), which scans the surfaces of other cells.

What they work on

  1. Determine how negative feedback loops, in which activated kinases (enzymes that add phosphate tags) dampen their own pathway, shape distinct T cell receptor signaling outcomes, using chemical tools and immunological assays.
  2. Identify how the protein makeup of TCR signaling complexes changes with feedback and with how strongly the receptor binds its ligand, using proximity labeling to tag neighboring proteins and mass spectrometry to identify them.
  3. Characterize long-term adaptive desensitization of TCR signaling caused by changes in gene expression, using RNA sequencing to measure which genes T cells switch on or off.

More about the research

Signaling proteins inside the T cell then interpret what the TCR detects. This machinery is extremely sensitive: it can spot a few foreign molecules among many very similar self molecules. How the cell decides whether to ignore a signal or switch on is still unclear. That gap matters because T cells are increasingly used as therapies.

Why it matters

T cell-based therapies depend on T cells responding to the right targets and ignoring the wrong ones. By defining how the signaling machinery inside T cells decides whether a molecule is a threat, this work could inform how therapeutic T cells are designed or tuned for treating human disease.
