A Multidisciplinary Golden Track for NSFC Funding
Knowledge Insight: DPP‑4 Research — A Multidisciplinary Golden Track for NSFC Funding
Published by ANT BIO PTE. LTD.
1. Core Concepts
Dipeptidyl peptidase‑4 (DPP‑4, also known as CD26) is a multifunctional serine protease that acts as a molecular switch at the intersection of metabolism, immunity, neurobiology, and oncology. Beyond its canonical role in glucose homeostasis, DPP‑4 cleaves a wide spectrum of substrates to modulate immune responses, gut–brain communication, and tumor progression, making it a high‑impact topic for National Natural Science Foundation of China (NSFC) applications.
2. Research Frontiers
DPP‑4 has evolved far beyond a diabetes drug target to become a central hub in modern biomedical research:
- Immune regulation and inflammatory disease
- Gut–brain–metabolism crosstalk
- Context‑dependent tumor suppression or promotion
- Substrate‑selective inhibition and non‑enzymatic signaling
- Biomarker development and precision intervention strategies

3. Research Significance
DPP‑4 integrates metabolic, immune, neural, and oncogenic pathways, offering transformative opportunities for NSFC‑funded innovation:
- Uncovers novel mechanisms of complex disease pathogenesis
- Enables development of safer, more selective therapeutics
- Bridges basic research and clinical translation
- Supports interdisciplinary collaboration across biochemistry, immunology, neuroscience, and oncology

4. Key Mechanisms & Application Directions
4.1 DPP‑4 as a Dual Immune Regulator
DPP‑4/CD26 modulates T‑cell activation, chemokine activity, and immune tolerance. It can either enhance anti‑tumor/anti‑infective immunity or promote immunosuppression, depending on cellular context and substrate processing.
NSFC Focus: Subset‑specific functions, substrate selectivity, and tissue‑targeted immune modulation.
4.2 DPP‑4 in the Gut–Brain–Metabolism Axis
DPP‑4 governs gut hormone (GLP‑1/GIP) stability and cleaves neuropeptides, linking peripheral metabolism to brain function, mood, and cognition.
NSFC Focus: Cell‑specific knockout models, microbiota crosstalk, and metabolic‑neurological comorbidity mechanisms.
4.3 Context‑Dependent Roles in Cancer
DPP‑4 exhibits paradoxical functions: it can suppress invasion or drive EMT, metastasis, and immune escape in a tumor‑ and stage‑specific manner.
NSFC Focus: Context‑dependent signaling, substrate profiling, and combination immunotherapy strategies.
4.4 Next‑Generation Intervention Strategies
- Substrate‑selective and allosteric modulators
- Non‑enzymatic protein–interaction inhibitors
- Tissue‑specific delivery systems
- Soluble DPP‑4 (sDPP‑4) as a clinical biomarker
NSFC Focus: Structural biology, chemical biology, nanomedicine, and clinical big data integration.
