Background
dipeptidyl peptldase Ⅳ (DPP4) is a biological molecule commonly studied in immunology research. It is commonly used as a molecular readout in mechanistic and biomarker-focused studies.
UniProt: P14740
Biological context
Researchers often monitor dipeptidyl peptldase Ⅳ in serum, plasma, and tissue homogenates to better understand themes such as innate and adaptive immune responses, cytokine signaling networks, and host–pathogen interactions. In many model systems, measured levels can shift with physiology, experimental perturbation, or disease-associated changes, making careful biological interpretation important.
Interpreting changes in measured levels
Depending on sample matrix and study design, increases or decreases in dipeptidyl peptldase Ⅳ may reflect differences in expression, secretion, turnover, or compartmentalization rather than a single mechanism. Interpretation is typically strengthened by evaluating related molecules (for example, cytokines, chemokines, acute-phase proteins, and immune-cell activation markers) and by keeping pre-analytical variables consistent across groups.
Nomenclature
In publications and databases, dipeptidyl peptldase Ⅳ may also appear under names such as Dpp4 and Cd26. When comparing studies, confirm that the reported analyte refers to the same molecule and species context.
Why ELISA data are widely used
ELISA is a common approach for quantitative measurement of proteins and biomarkers in complex samples, enabling comparisons across experimental groups and time points. When integrating results with other readouts, consider species biology, sample type, and the broader pathway context that dipeptidyl peptldase Ⅳ participates in.
