Rewiring STAT signaling from the cell surface with Trikine immunotherapeutics

GSE316257 Mus musculus Expression profiling by high throughput sequencing 6 samples Submitted 2026/01/25 Platform GPL34290
Summary
Cytokines dimerize two receptor chains to activate Janus kinases and STAT transcription factors that regulate immune cells but have therapeutic liabilities. We engineered “Trikines” to compel cis formation of three-chain cytokine receptor complexes at the cell surface that induce bespoke STAT transcriptional signaling programs optimized for therapeutic efficacy. Designed Trikines co-activated pSTAT5 and pSTAT3 signatures distinct from any natural cytokines, by assembling trimeric combinations of Interleukin-2 (IL-2), Interleukin-10 (IL-10), and Interleukin-21 (IL-21) receptors. An IL-2-based-Trikine restrained terminal differentiation of T cells, promoted stemness, and enhanced durability of tumor control without toxicity. Unexpectedly, an IL-10-based Trikine induced immune infiltration into poorly immunogenic tumors, showing striking efficacy in small cell lung cancer and pancreatic cancer models. Trikines obviate the need for cell engineering to customize STAT signatures for immunotherapy
