Custom design and engineering of cytokine constructs (muteins, switch receptors, orthogonal pairs) tailored to client-specific cell therapeutic platforms (CAR-T, TIL, NK) and target solid/liquid tumor indications.
Creative Biolabs provides custom-designed genetic and protein modifications that overcome the major hurdles in advanced cell therapy research, namely low in vivo persistence and off-target toxicity. We provide fully characterized cytokine constructs, optimized cell transduction protocols, and comprehensive pre-clinical data packages. Clients gain assets with enhanced tumor-specific efficacy, maximized cellular persistence via stemness maintenance, and significantly de-risked safety profiles through highly selective or inducible signaling pathways, accelerating their path toward translational success.
Cytokine Engineering is the strategic modification of native cytokines or their receptors to achieve targeted, potent, and safe signaling exclusively at the tumor site for research purposes. This approach is validated by numerous cited literature summaries showing that augmenting T-cell signal 3 by transgenic cytokine expression or engineered receptors significantly improves in vivo anti-tumor activity and cell persistence.

Custom design and engineering of cytokine constructs (muteins, switch receptors, orthogonal pairs) tailored to client-specific cell therapeutic platforms (CAR-T, TIL, NK) and target solid/liquid tumor indications.
Implementation of advanced genetic safety circuits (e.g., NFAT-responsive promoter) for inducible, tumor-conditional cytokine expression (e.g., IL-12), offering best-in-class safety profiles and minimizing systemic toxicity.
Optimization for long-term cell persistence through membrane-bound IL-15 formats, ensuring engineered T-cells maintain the critical stem cell-like memory phenotype required for sustained in vivo efficacy and lasting remission.
This service encompasses the design of "armored" cells that are self-sufficient. We genetically modify your ACT product (CAR-T, TIL, etc.) to intrinsically express or secrete engineered cytokines.
Learn More →Focuses on engineering locus mutations (muteins) to eliminate undesirable binding to IL-2Rα (CD25), thereby preventing the activation and proliferation of regulatory T cells (Tregs) while strongly activating effector T cells.
Learn More →We engineer both the cytokine (the ligand) and a component of its receptor (e.g., IL-2Rβ) so that the ortho-cytokine only recognizes and activates the ortho-receptor expressed on your research cells.

|---|---|
| Precision and Safety | Our expertise in cytokine muteins eliminates binding to toxic, low-affinity receptor subunits, drastically lowering systemic toxicity profiles. |
| TME Overcome | We specialize in chimeric cytokine receptors that convert immunosuppressive signals (e.g., IL-4 or TGF-β) prevalent in solid tumors into beneficial proliferative signals (e.g., IL-7 signaling), turning the TME against itself. |
| Safety Control | For high-potency molecules like IL-12, we employ NFAT-responsive promoter gene circuits to ensure expression is strictly conditional upon tumor engagement, preventing systemic toxicity. |

A: Safety is prioritized through the deployment of Inducible Expression systems, such as the NFAT-responsive promoter. This genetic circuit strictly correlates IL-12 production with T-cell activation status, ensuring cytokine secretion is localized and dependent upon tumor antigen engagement. This targeted action dramatically reduces the risk of systemic inflammation relative to constitutive expression.
A: Affirmative. Our advanced chimeric cytokine receptors are specifically engineered for this purpose. These receptors bind to inhibitory TME signals (e.g., IL-4 or TGF-β) but convert the signal into a pro-proliferative Signal 3 (e.g., IL-7 signaling). This mechanism effectively repurposes the tumor's defensive response.
