NKG2A, a New Kid on the Immune Checkpoint Block [PDF]
One of the major breakthroughs of cancer immunotherapy has come from blocking immune checkpoint molecules on tumor-reactive T cells. Now, two studies examine targeting of a novel immune checkpoint, NKG2A, that can be expressed on both NK cells and on CD8+ T cells, either combined with a tumor-targeting antibody or with a tumor-specific vaccine.

Decrease of peripheral and intestinal NKG2A-positive T cells in patients with ulcerative colitis. [PDF]
To investigate the role of inhibitory natural killer receptors (iNKRs) in inflammatory bowel disease (IBD), we analyzed the expression of NKG2A, one of the iNKRs, on T cells in a mouse colitis model and human IBD.

TCR Specificity Dictates CD94/NKG2A Expression by Human CTL [PDF]
Activating and inhibitory CD94/NKG2 receptors regulate CTL responses by altering TCR signaling, thus modifying antigen activation thresholds set during thymic selection. To determine whether their expression was linked to TCR specificity, we examined the TCR repertoire of oligoclonal CTL expansions found in human blood and tissues.

Cell Therapy Using Anti-NKG2A Pretreated Natural Killer Cells in Patients with Hepatocellular Carcinoma [PDF]
Purpose: The activities and functions of natural killer (NK) cells are regulated by a limited repertoire of activating and inhibitory receptors. Thus, we provided a study of inhibition of the NKG2A using monoclonal antibodies (mAbs), and as a primary ...

Antiviral treatment alters the frequency of activating and inhibitory receptor-expressing natural killer cells in chronic Hepatitis B virus infected patients [PDF]
Natural killer (NK) cells play a critical role in innate antiviral immunity, but little is known about the impact of antiviral therapy on the frequency of NK cell subsets.

NKG2A Inhibits Invariant NKT Cell Activation in Hepatic Injury [PDF]
Abstract Activation of invariant NKT (iNKT) cells in the liver is generally regarded as the critical step for Con A-induced hepatitis, and the role of NK cell receptors for iNKT cell activation is still controversial. In this study we show that blockade of the NKG2A-mediated inhibitory signal with antagonistic anti-NKG2A/C/E mAb (20d5 ...

Expression analysis of HLA-E and NKG2A and NKG2C receptors points at a role for natural killer function in ankylosing spondylitis [PDF]
Background. Ankylosing Spondylitis (AS) is a complex chronic inflammatory disease strongly associated with the majority of HLA-B27 alleles. HLA-E are non-classical MHC class I molecules that specifically interact with the natural killer receptors NKG2A ...

Increased NKG2A+CD8+ T-cell exhaustion in patients with adenomyosis
Immune dysregulation has long been proposed to be associated with adenomyosis, but the underlying mediators and mechanisms remain largely unexplored. Here, we used flow cytometry to investigate the alterations in immune cell subsets in adenomyotic uteri and analyze the phenotype and function of abnormal immune cells.

Natural killer (NK) cell-based immunotherapy is a promising therapy for cancer patients. Inhibitory killer immunoglobulin-like receptors (KIRs) and NKG2A are required for NK cell licensing, but can also inhibit NK cell effector function.

Expression of CD226 is associated to but not required for NK cell education [PDF]
DNAX accessory molecule-1 (DNAM-1, also known as CD226) is an activating receptor expressed on subsets of natural killer (NK) and T cells, interacts with its ligands CD155 or CD112, and has co-varied expression with inhibitory receptors. Since inhibitory
