Cytokines are proteins that regulate immunity and cellular functions. This review summarizes their properties and ongoing clinical trials investigating their use as cancer immunotherapies.
Area of Science:
- Immunology
- Oncology
- Molecular Biology
Background:
- Cancer immunotherapies have advanced significantly over the last two decades.
- Approaches include specific therapies (monoclonal antibodies, vaccines, cell-based) and less selective methods (adjuvants, immunomodulatory cytokines).
- Cytokines are pleiotropic proteins crucial for innate and adaptive immunity, regulating diverse cellular functions via specific receptors and signaling pathways.
Purpose of the Study:
- To summarize the biological properties of cytokines.
- To discuss the progress of ongoing clinical studies evaluating cytokines in cancer treatment.
Main Methods:
- Review of biological properties of cytokines.
- Summary of ongoing clinical trials on cytokine-based cancer immunotherapies.
Main Results:
- Cytokines exhibit pleiotropic effects, influencing cell proliferation, differentiation, inflammation, and cell death.
- Cytokine networks involve complex self-amplificatory or self-inhibitory signaling cascades.
- Ongoing clinical studies are evaluating the safety and efficacy of cytokines as immunomodulatory agents against cancer.
Conclusions:
- Cytokines play a central role in immune regulation and have potential as cancer therapeutics.
- Further clinical evaluation is necessary to determine the optimal use of cytokines in cancer treatment.
