| Περίληψη: | CAR T-cell therapy has delivered durable remissions in several hematologic cancers, yet activity in solid tumors and extension to immune-mediated diseases remain constrained by recurring failure modes: imperfect antigen specificity, inadequate trafficking, progressive dysfunction under chronic stimulation, and toxic inflammatory syndromes. Early reports of CAR-based immune "resets" in refractory autoimmune disease amplify both promise and stakes, because acceptable risk is lower than in cancer and "on-target" effects may still be clinically unacceptable if they create long-term immunodeficiency. This review treats CAR T optimization as multi-layer reprogramming across genetic circuitry, epigenetic state, metabolism, and the tissue microenvironment. We argue that many celebrated single-layer upgrades (stronger signaling, checkpoint deletion, constitutive cytokine armoring) often trade one failure mode for another. Instead, the most credible path to simultaneously improving efficacy and safety is disciplined, failure-mode-driven design: (i) programmable antigen logic and titratable activation to reduce off-tissue damage; (ii) epigenetic programming that preserves renewable functional states without removing essential restraints; (iii) metabolic rewiring evaluated under physiologic stress conditions; and (iv) microenvironment-aware strategies that prioritize access and local control over brute-force potency.
