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 ...
Impairment in natural killer cells editing of immature dendritic cells by infection with a virulent Trypanosoma cruzi population
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 ...
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 ...
Altered Glycosylation Contributes to Placental Dysfunction Upon Early Disruption of the NK Cell-DC Dynamics
(Frontiers Media, 2020-07)
Immune cells [e. g., dendritic cells (DC) and natural killer (NK) cells] are critical players during the pre-placentation stage for successful mammalian pregnancy. Proper placental and fetal development relies on balanced ...
The tumor antigen N-glycolyl-GM3 is a human CD1d ligand capable of mediating B cell and natural killer T cell interaction
The expression of N-glycolyl-monosialodihexosyl-ganglioside (NGcGM3) in humans is restricted to cancer cells; therefore, it is a tumor antigen. There are measurable quantities of circulating anti-NGcGM3 antibodies (aNGcGM3 ...
Primary immunodeficiencies unravel the role of IL-2/CD25/STAT5b in human natural killer cell maturation
(Frontiers Media S.A., 2018-06-22)
Natural killer (NK) cells play a pivotal role during immunity against viruses and circumstantial evidence also indicates that they can protect the host against developing tumors. Peripheral blood NK cells comprise ...
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 ...
Regulatory functions of NK cells during infections and cancer
(Federation of American Societies for Experimental Biology, 2021-01)
After recognition, NK cells can kill susceptible target cells through perforin-dependent mechanisms or by inducing death receptor-mediated apoptosis, and they can also secrete cytokines that are pivotal for immunomodulation. ...
