How T cells' signaling machinery tells apart harmful and harmless molecules

Defining the Unique Properties of the Distinct Signaling Machinery Used by the TCR

['FUNDING_P01'] · UNIVERSITY OF CALIFORNIA, SAN FRANCISCO · NIH-11325012

Researchers are looking at how parts of T cells decide whether a bound molecule is harmless or dangerous so findings can help people with immune-related conditions.

What this research studies

This multi-team project at UCSF brings together structural biology, proteomics, biophysics, imaging and computer modeling to map how the T cell receptor (TCR) sends signals when it binds different peptides. Scientists will focus on the enzymes (kinases) and the signaling circuits that add and read phosphate tags to decide whether a bound peptide is self or an invader. They use high-resolution protein structure work, mass spectrometry, live-cell imaging, and computational analysis to observe these molecular events. Over four coordinated projects, teams aim to reveal the unique machinery that enables precise ligand discrimination.

Who could benefit from this research

Good fit: People with autoimmune diseases, organ transplant recipients, or patients considering T cell therapies are most likely to benefit from advances informed by this research.

Not a fit: Patients with conditions unrelated to T cells or immune signaling, such as many isolated orthopedic injuries or non-immune metabolic disorders, are unlikely to receive direct benefit from this project.

Why it matters

Potential benefit: If successful, this work could point to new ways to prevent autoimmune attacks or improve T cell–based therapies for cancer and other diseases.

How similar studies have performed: Previous research has clarified many elements of TCR signaling, but this integrated, multi-disciplinary program applies newer proteomics and imaging approaches to answer remaining, unresolved questions.
