synthetic suppressor T cells
Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
Synthetic suppressor T cells are a customizable platform to potentially treat autoimmune diseases, organ rejection, and CAR T cell toxicities with spatial precision.
Usefulness & Problems

Published Workflows
Engineering synthetic suppressor T cells that execute locally targeted immunoprotective programs.
2024Objective: Engineer conventional CD4+ T cells to execute antigen-triggered, locally targeted immunoprotective programs that suppress immune attack without systemic suppression.
Why it works: The workflow couples local antigen recognition through synNotch receptors to production of suppressive payloads, then screens a diverse library to identify programs that most strongly suppress cytotoxic T cell attack while preserving local rather than systemic action.

Stages
- 1.Engineering conventional CD4+ T cells with synNotch-controlled suppressive programs(library_build)
This stage creates the engineered suppressor-cell candidates needed for downstream screening of different suppression programs.
Selection: Construction of engineered CD4+ T cells in which synNotch receptors drive antigen-triggered anti-inflammatory payload production.
- 2.Screening a diverse library of suppression programs(broad_screen)
This stage identifies which suppressive payload programs most effectively inhibit cytotoxic T cell attack.
Selection: Strength of suppression of cytotoxic T cell attack.
- 3.Application testing of bespoke regulatory programs in tissue-protection settings(confirmatory_validation)
This stage confirms that top suppressor programs translate from screening hits into functional tissue protection in application-relevant models.
Selection: Ability of engineered suppressor T cells to protect tissues from immune attack without systemic suppression.
