Cytokine-based NK cell engineering for cancer immunotherapy

Area of Science:

• Immunology
• Cancer Biology
• Cell Therapy

Background:

• Natural killer (NK) cells are vital innate immune cells for antiviral and antitumor responses.
• NK cells are increasingly important in cancer immunotherapy, with cytokines regulating their function.
• Cytokines are key for NK cell development, survival, proliferation, and effector functions.

Purpose of the Study:

• To review recent advancements in cytokine-driven NK cell engineering for immunotherapy.
• To outline cytokines regulating NK cell biology, signaling pathways, and functions.
• To examine cytokine-based engineering strategies, particularly IL-15 applications.

Main Methods:

• Literature review of cytokine-driven NK cell engineering strategies.
• Analysis of cytokine signaling pathways impacting NK cell proliferation, activation, and cytotoxicity.
• Examination of IL-15-based engineering formats (secreted, membrane-bound, fusion).

Main Results:

• Cytokines critically regulate NK cell biology and effector functions.
• IL-15 is a key cytokine for NK cell expansion, maintenance, and persistence.
• Various IL-15 formats (secreted, mbIL-15, fusion) enhance NK cell therapeutic potential.

Conclusions:

• Cytokine-driven NK cell engineering holds significant promise for cancer immunotherapy.
• Optimizing cytokine signaling and expression systems can improve therapeutic efficacy.
• Future research may lead to programmable NK cell therapies beyond empirical expansion.
