Receptor engineering strategies, including switch/inverted and orthogonal designs, restrict cytokine signaling to CAR-T cells, thereby enhancing both specificity and safety. Beyond CAR-T engineering, external cell-based 'cytokine factories' and immune-cytokines further underscore the versatility of localized cytokine delivery strategies.
