The abstract indicates that clinical Treg approaches involved ex vivo-expanded Tregs, implying cell isolation and expansion before use.; requires ex vivo expansion for the clinical Treg approach described in the abstract
The abstract does not show that dosing, manufacturing, antigen specificity, and long-term safety have been fully resolved.; further research is needed to optimize dosing and manufacture; long-term safety concerns remain
