DPPIV/CD26 plays an important role in many biological and pathological processes. It functions as T cell-activating molecule (THAM). It serves as a cofactor for entry of HIV in CD4+ cells. It binds adenosine deaminase, the deficiency of which causes severe combined immunodeficiency disease in humans. It cleaves chemokines such as stromal-cell-derived factor 1 alpha and macrophage-derived chemokine. It degrades peptide hormones such as glucagon. It truncates procalcitonin, a marker for systemic bacterial infections with elevated levels detected in patients with thermal injury, sepsis and severe infection, and in children with bacterial meningitis.

Expression of different markers in the eight human colon cancer cell lines analyzed. (A) Western blot analysis of EpCAM, LGR5, CD26, E-cadherin and vimentin expression in total cell extracts from the eight cell lines (20 μg of protein in each line). Data shown are representative of three experiments. (B) E-cadherin and EpCAM expression analysis by immunofluorescence in HT-29 and Caco-2 cells. (C) CD44 and CD26 expression analysis by immunofluorescence in HT-29 and Caco-2 cells. (D) LGR5 expression analysis by immunofluorescence in DLD-1 and Caco-2 cells. Nuclei were stained with DAPI.

Detection of Human DPPIV/CD26 by Immunocytochemistry/ Immunofluorescence
Comparison of histone modifier sets between two hepatic cell cultures.(A) Differentiation scheme of hESC towards Hepatocyte-like cells (Hep-like). (B) Hep-like cells were generated from hESC and stained with antibodies specific for DPP4 and albumin. Nuclei were stained with the DNA dye H-33342 (blue). Scale bars: 100 µm. (C) RT-qPCR data from three independent experiments for hepatic (ALB, CYP3A, CYP7A1, DPP4, HNF4, MET) and neuronal (TH, DCX, TUBB3) markers. Relative gene expression was calculated using hESC as a calibrator and a set of three reference genes (HPRT, RPL13A, GAPDH). (D) Transcript levels of epigenetic modifiers were measured by RT-qPCR in human liver (huHep), Hep-like islets (Hep-like) and embryonic stem cells (hESC). Data for huHep and Hep-like are indicated as relative change compared to hESC (as reference cell). For comparative display, a scatter plot was constructed so that differentially expressed genes that show pos. association (between Hep-like and huHep) are found in red fields, and those that differed in the sense of regulation fall into blue fields. Values of >10 were set to 10. For quadrant count ratio analysis (QCR) only expression values >2 or <−2 were included. (E) The data measured in D were plotted as heat map, sorted according to rel. huHep expression levels. Transcripts that were >2-fold higher expressed in tissue than in hESC are marked in red, >2-fold lower expression is marked in blue. The color scale ranges from a fold regulation of −20 (dark blue) to +20 (dark red). Measures of variance and p-values are indicated in the supplemental material, genes not regulated significantly (vs. hESC) are displayed as “n.s.”.
