Abstract
Therapies using NK cells (NKc) expanded/activated ex vivo or stimulated in vivo with new immunostimulatory agents offer alternative opportunities for patients with recurrent/refractory tumors, but relevant biomarkers to guide the selection of patients are required for optimum results. Overall survival of 249 solid cancer patients was evaluated in relation to the genetics and/or the expression on peripheral blood NKcs of inhibitory and activating killer-cell immunoglobulin-like receptors (iKIR and aKIR, respectively), HLA class I ligands, CD226 (also known as DNAM-1), and NKG2A. Compared with patients with higher expression, patients with low expression of CD226 on total NKcs showed shorter mean overall survival (60.7 vs. 98.0 months, P < 0.001), which was further reduced in presence of telomeric aKIRs (KIR2DS1-DS5 and/or KIR3DS1, 31.6 vs. 96.8 months, P < 0.001). KIR2DL2/S2+, KIR3DL1+, KIR2DL1+, and KIR2DL3+ NKc subsets in the presence of their cognate ligands primarily contributed to shortening patients' overall survival by increasing the sensitivity to CD226 downmodulation in aKIR-rich telomeric genotypes. In patients with high tumor burden who died during the follow-up period, aKIR-rich telomeric genotypes were associated with: (i) specific downmodulation of CD226 on educated NKcs but not on CD8+ T cells or uneducated NKcs, (ii) lower expression of CD226 and higher expression of NKG2A on aKIR+ NKcs, and (iii) lower numbers of total CD56dim NKcs. The reduced expression of CD226 on NKcs with aKIR-rich genotypes may be a biomarker indicative of NKc hyporesponsiveness in patients that could benefit from new NKc immune-stimulatory therapies.

Abstract
Natural killer cell (NKc)-based therapies offer promising outcomes in patients with tumors, but they could improve with appropriate selection of donors and optimization of methods to expand NKcs in vitro Education through licensing interactions of inhibitory killer cell immunoglobulin-like receptors (iKIR) and NKG2A with their cognate HLA class-I ligands optimizes NKc functional competence. This work has evaluated the role of licensing interactions in NKc differentiation and the survival of cancer patients. We have analyzed KIR and KIR-ligand genes, and the expression of activating (CD16 and DNAM-1/CD226) and inhibitory (NKG2A and iKIRs) receptors on peripheral blood NKcs in 621 healthy controls and 249 solid cancer patients (80 melanoma, 80 bladder, and 89 ovarian). Licensing interactions upregulated the expression of activating CD226, reduced that of iKIR receptors, and shifted the CD226/iKIR receptor ratio on NKc membranes to activating receptors. A high tumor burden decreased CD226 expression, reduced the ratio of CD226/iKIR, and negatively affected patient survival. The progression-free survival (38.1 vs. 67.0 months, P < 0.002) and overall survival (56.3 vs. 99.6 months, P < 0.00001) were significantly shorter in patients with lower expression of CD226 on NKcs. Hence, transformed cells can downmodulate these licensing-driven receptor rearrangements as a specific mechanism to escape NKc immune surveillance. Our results suggest the importance of the CD226/iKIR receptor ratio of NKcs induced by licensing interactions as critical determinants for solid cancer immune surveillance, and may provide predictive biomarkers for patient survival that may also improve the selection of donors for NKc immunotherapy.

Abstract
Background Multiple renal arteries in kidney grafts have been associated with an increased rate of vascular and urologic complications. Our objective is to compare the outcome of transplanted patients who receive a single pedicle kidney with those who receive a multiple arterial graft. Objectives To find our the differences in the outcome and complications in patients undergoing kidney transplantation with one single artery or with multiple arteries. Patients and Methods We analyzed 147 kidney transplantations, (all performed in our hospital over a 3 year period). population divided into two groups: group A for those who presented with only one renal artery, or group B for those with more than one renal artery. Homogeneous vascular reconstructions and implantation rules were applied in all patients. We compared the rates of renal failure between the two groups, urinary and vascular complications, patient and graft survivals and the levels of creatinine clearance during the first year of post-transplantation. Results No significant differences were found between the two groups regarding to the values analyzed. Conclusions As many other authors, we do believe that the presence of multiple renal arteries in kidney grafts should not be considered as a predictive factor of transplantation failure.
