Published Workflows
Objective: Improve CAR-T cell engineering by using advanced screening methods that better predict CAR-T function and in vivo therapeutic performance than affinity-only in vitro screening.
Why it works: The review states that affinity-only in vitro screening often fails to predict T cell function and in vivo performance, whereas advanced cell-based platforms, direct CAR activation readouts, and primary-T-cell library screening provide more functionally informative and physiologically relevant data.

Stages
- 1.Affinity-focused in vitro CAR screening(broad_screen)
This is described as the prevailing current screening approach used to assess CAR candidates.
Selection: antigen binding affinity in vitro
- 2.Reporter cell line-based cell screening(broad_screen)
Advanced cell-based screening platforms were developed to overcome the limitations of affinity-only in vitro screening.
Selection: detection of antigen binding properties or CAR-T cell activation markers in reporter cell lines
- 3.FRET-based direct CAR activation assessment(functional_characterization)
The review emphasizes this system because it directly assesses CAR activation upon antigen binding and offers speed and scalability advantages for predicting functionality.
Selection: direct assessment of CAR activation upon antigen binding using a FRET-based immunological synapse biosensor
- 4.Primary T-cell CAR library screening(secondary_characterization)
The review states that direct screening in primary T cells provides more physiologically relevant data.
Selection: screening CAR libraries directly in primary T cells

cofactor dependency: cofactor requirement unknownencoding mode: genetically encodedimplementation constraint: context specific validationoperating role: sensor
The platform requires a FRET-based immunological synapse biosensor setup. The abstract does not specify additional hardware, constructs, or assay reagents.; requires a FRET-based immunological synapse biosensor platform
Independent follow-up evidence is still limited. Validation breadth across biological contexts is still narrow. Independent reuse still looks limited, so the evidence base may be fragile. No canonical validation observations are stored yet, so context-specific performance remains under-specified.
