Chronic Kidney Disease is associated with an increase of Intimal Dendritic cells in a comparative autopsy study

Background: Chronic Kidney Disease (CKD) and inflammation are risk factors for atherosclerotic vascular disease (ASVD). In inflammatory conditions, Nuclear Factor-kappa B (NF-kappa B) is frequently activated and it has been detected in human ASVD. In this work, we investigated if the degree of inflammation and of NF-kappa B activation were increased in the aorta of patients with CKD. Methods: This is a case-control pilot study performed on 30 abdominal aorta samples from 10 human autopsies. Cases were patients with CKD and controls patients with normal glomerular filtration rate (eGFR). Infiltrating mononuclear cells (S100(+), CD3(+), CD40(+), CD40L(+)) and activation of NF-kappa B were identified by immunohistochemistry. Findings: The number of cells in the intima which showed activated nuclear NF-.B correlated with severity of ASVD lesions (r = 0.56, p = 0.003), with numbers of CD3(+) lymphocytes in adventitia (r = 0.50, p = 0.008), with numbers of CD40(+) cells in the intima (r = 0.59, p = 0.002) or in the adventitia (r = 0.45, p = 0.02), and with numbers of CD40L(+) cells in the intima (r = 0.51, p = 0.011). Increased numbers of S100(+) Intimal Dendritic cells (IDCs) were associated with ASVD (p = 0.03) and CKD (p = 0.01). Conclusions: Number of CD3(+) cells, of CD40(+) cells, of CD40L(+) cells and the degree of NF-kappa B activation were increased in ASVD lesions suggesting a role for the adaptive T cell in the development of ASVD lesions. IDCs were associated both with ASVD and CKD suggesting a role of these cells in the pathogenesis of ASVD in CKD

High expression of ecto-nucleotidases CD39 and CD73 in human endometrial tumors

One of the strategies used by tumors to evade immunosurveillance is the accumulation of extracellular adenosine, which has immunosupressive and tumor promoting effects. The study of the mechanisms leading to adenosine formation at the tumor interstitium are therefore of great interest in oncology. The dominant pathway generating extracellular adenosine in tumors is the dephosphorylation of ATP by ecto-nucleotidases. Two of these enzymes acting sequentially, CD39 and CD73, efficiently hydrolyze extracellular ATP to adenosine. They have been found to play a crucial role in a variety of tumors, but there were no data concerning endometrial cancer, the most frequent of the invasive tumors of the female genital tract. The aim of the present work is to study the expression of CD39 and CD73 in human endometrial cancer. We have analyzed protein and gene expression, as well as enzyme activity, in type I endometrioid adenocarcinomas and type II serous adenocarcinomas and their nonpathological endometrial counterparts. High levels of both enzymes were found in tumor samples, with significantly increased expression of CD39 in type II serous tumors, which also coincided with the higher tumor grade. Our results reinforce the involvement of the adenosinergic system in cancer, emphasizing the relevance of ecto-nucleotidases as emerging therapeutic targets in oncology
