Intrahepatic and peripheral blood phenotypes of natural killer and T cells: differential surface expression of killer cell immunoglobulin-like receptors
(Wiley Blackwell Publishing, Inc, 2018-06)
Deep characterization of the frequencies, phenotypes and functionalities of liver and peripheral blood natural killer (NK), natural killer T (NKT) and T cells from healthy individuals is an essential step to further interpret ...
The clinical features of patients with chronic hepatitis C virus infections are associated with killer cell immunoglobulin-like receptor genes and their expression on the surface of natural killer cells
(Frontiers Media S.A., 2018-01)
Killer cell immunoglobulin-like receptor (KIR) genes are known to play a role in the acute phase of hepatitis C virus (HCV) infection. The present study investigated their roles in chronic HCV (CHCV) infection by analyzing ...
Production of a novel killer toxin from Saccharomyces eubayanus using agro-industrial waste and its application against wine spoilage yeasts
(Springer, 2019-01)
The juicing industry generates large amounts of waste that mostly lack commercial value and, in the absence of waste treatment policies, produces environmental pollution. Also, microbiological spoilage is a major concern ...
Characterization of the killer toxin KTCf20 from wickerhamomyces anomalus, a potential biocontrol agent against wine spoilage yeasts
(Elsevier, 2018-06)
Wickerhamomyces anomalus Cf20 secretes the killer toxin KTCf20 that inhibits several wine spoilage yeasts of the species Pichia guilliermondii, P. membranifaciens, Brettanomyces bruxellensis and Dekkera anomala. KTCf20 ...
Spontaneous and cytokine induced natural killer cytotoxicity in patients with Cushing´s disease
(Lippincott Williams, 2003-11)
Patients with endogenous hypercortisolism are prone to develop infectious diseases. In this study, we investigated the spontaneous and in vitro response to interleukin-2 (LAK) or interferon -a (IFN-a NK) natural killer ...
Impairment in natural killer cells editing of immature dendritic cells by infection with a virulent Trypanosoma cruzi population
(Karger, 2013-05)
Early interactions between natural killer (NK) and dendritic cells (DC) shape the immune response at the frontier of innate and adaptive immunity. Activated NK cells participate in maturation or deletion of DCs that remain ...
Purification and characterization of Saccharomyces eubayanus killer toxin: Biocontrol effectiveness against wine spoilage yeasts
(Elsevier B.V., 2020-10)
Microbiological contamination by spoilage yeasts species are frequent during winemaking, and biological control using antagonistic yeasts is considered a more beneficial alternative to conventional synthetic antimicrobials. ...
Increased frequencies of activating natural killer receptors are associated with liver injury in individuals who do not eliminate hepatitis C virus
(Wiley Blackwell Publishing, Inc, 2007-12)
This study was designed to investigate the role of KIR genes in the outcome of HCV infection. In patients who cleared the virus (HCV RNA-) we found a decrease of 2DL2 (p=0.04), and 2DS2 (p=0.014) accompanied by an increase ...
Interleukin (IL)-23 stimulates IFN-γ secretion by CD56bright natural killer cells and enhances IL-18-driven dendritic cells activation
(Frontiers Research Foundation, 2018-01)
Interleukin (IL)-23 is a member of the IL-12 family of cytokines that, as the other members of this family, is secreted by monocytes, macrophages, and dendritic cells (DC) upon recognition of bacterial, viral, and fungal ...
KIR receptors and HLA-C in the maintenance of pregnancy
(Wiley Blackwell Publishing, Inc, 2007-12)
The present study demonstrated that patients who have recurrent spontaneous abortions (RSA) presented a decreased number of killer immunoglobulin-like inhibitory receptors (KIR), in particular KIR2DL2. The KIR AA genotype ...
