13. this study shows that CD26 expression is down-regulated on CD8(+) T cells in patients with Hashimoto's thyroiditis

14. Several isoforms of DPP-IV and FAP are present in glioblastoma tissue. The absence of alkaline isoforms of both enzymes in glioma cell lines however suggests that isoforms from other, most likely stromal, cell types contribute to the overall pattern seen in glioblastoma tissues.

15. Data suggest that dipeptidyl peptidase 4 (DPPIV) gene polymorphism influences disease susceptibility and acute pancreatitis (AP) severity.

16. High levels of DPP4a are independently associated with an increased rate of no-reflow events.

17. DPP-4 activity and GLP-1total levels were higher in patients with microvascular complications associated with T2DM. Contrary to expectations, no negative correlation was seen between GLP-1 and DDP-4 levels. This result suggests the possible inefficacy of DDP-4 activity as a marker to predict in vivo degradation of endogenous GLP-1.

18. The study showed that DPP-4 inhibitor use does not modify the risk of bone fracture compared with placebo or other anti-diabetic medications in patients with type 2 diabetes.

19. A close connection between SerpinB3 and DPPPIV has been identified, but further studies are required to better understand the mechanism by which these proteins communicate and exert metabolic effects in hepatocellular carcinoma.

20. There is a U-shaped association of serum DPP-IV with mortality in chronic heart failure patients.

Cow (Bovine) Dipeptidyl-Peptidase 4 (DPP4) interaction partners

1. Results describe a proline-rich cytokine from neurosecretory granules that represents a new natural substrate for Dipeptidyl Peptidase IV (DPPIV).

2. This and other dipeptidyl peptidases can be isolated from bovine testes.

3. Data demonstrate that dipeptidyl peptidase II can form a complex with adenosine deaminase, but with one order of magnitude higher dissociation constant than that of DPPIV.

Pig (Porcine) Dipeptidyl-Peptidase 4 (DPP4) interaction partners

1. This study shows that porcine DPP-IV is generally inhibited with greater potency by protein-derived peptides than is the human enzyme

2. DPP-IV from porcine kidney cortex was characterized.

3. Neutral endopeptidase 24.11 and DPP-IV is superior to DPP-IV inhibition alone in preserving intact GLP-1, which implies possibility that the combination has therapeutic potential.

4. Results describe the distribution of dipeptidyl peptidase IV-like activity enzymes in porcine tissue sections by RT-PCR.

Mouse (Murine) Dipeptidyl-Peptidase 4 (DPP4) interaction partners

1. These data indicate that DPP-4 is modulated in a tissue specific manner and is dependent on physiological conditions such as hyperglycaemia and insulin resistance, suggesting a significant role in disorders such as diabetes.

2. DPP4 activity when compared to healthy controls. Analysis of Dpp4-Liv-Tg mice revealed elevated systemic DPP4 activity and diminished active GLP-1 levels.

3. hepatocyte DPP4 promotes visceral adipose tissue inflammation and insulin resistance in obesity, and targeting this pathway may have metabolic benefits that are distinct from those observed with oral DPP4 inhibitors

5. Chronic stress accelerates DPP4-mediated GLP-1 degradation and alters plasma adiponectin, accelerating vascular senescence and impairing ischemia-induced neovascularization.

6. p53 limits ferroptosis of colorectal cancer cells by blocking DPP4 activity.

7. DPP4 can regulate chronic stress-induced hematopoietic stemc cell activation and inflammatory cell production via an Adrbeta3/CXCL12-dependent mechanism that is mediated by the GLP-1/GLP-1R axis.

8. DPPIV-knockout mice showed attenuation of scratching in psoriatic pruritus disease model.

9. Actions of several substrate chemokines might be potentiated by downregulation of DPP-4, synergistically with upregulation of chemokines and their receptors in adipose tissues of obese mice.

10. Inhibition of DPP-4 activity by linagliptin reverses Western diet-induced diastolic dysfunction, possibly by targeting TRAF3IP2 expression and its downstream inflammatory signaling.

11. DPP4 is pro-fibrotic in Carbon tetrachloride-induced liver fibrosis.

20. the data show that glucose-induced expression of Dpp4 in the liver is facilitated by demethylation of the Dpp4 gene early in life. This might contribute to early deteriorations in hepatic function, which in turn result in metabolic disease such as hepatosteatosis later in life.
