KIR gene content in amerindians indicates influence of demographic factors. [PDF]

open access: yesPLoS ONE, 2013
Although the KIR gene content polymorphism has been studied worldwide, only a few isolated or Amerindian populations have been analyzed. This extremely diverse gene family codifies receptors that are expressed mainly in NK cells and bind HLA class I ...

Phosphotyrosines in the killer cell inhibitory receptor motif of NKB1 are required for negative signaling and for association with protein tyrosine phosphatase 1C. [PDF]

open access: yes, 1996
NKB1 is one member of a growing family of killer cell inhibitory receptors (KIR). It is expressed on natural killer (NK) cells and T cells, and has been shown to inhibit cytolytic functions of these cells upon interacting with its ligand, HLA-B (Bw4). We

Reprogramming Antitumor Immunity: NK Cell Strategies to Navigate the Immunosuppressive Tumor Microenvironment

open access: yesAdvanced Science, EarlyView.
ABSTRACT Tumor immune escape is a major barrier to durable cancer immunotherapy, as advanced malignancies create a tumor microenvironment (TME) that preferentially exhausts and disables T cell responses. While most approved cell therapies are T cell‐based, this limitation motivates the exploration of an alternative effector cell platform.

The Size of Activating and Inhibitory Killer Ig-like Receptor Nanoclusters Is Controlled by the Transmembrane Sequence and Affects Signaling

open access: yesCell Reports, 2016
Super-resolution microscopy has revealed that immune cell receptors are organized in nanoscale clusters at cell surfaces and immune synapses. However, mechanisms and functions for this nanoscale organization remain unclear. Here, we used super-resolution

Deciphering the killer-cell immunoglobulin-like receptor system at super-resolution for natural killer and T-cell biology. [PDF]

open access: yes, 2016
Killer-cell immunoglobulin-like receptors (KIRs) are components of two fundamental biological systems essential for human health and survival. First, they contribute to host immune responses, both innate and adaptive, through their expression by natural ...

Mature T‐cell leukemia/lymphoma with an NK‐like immunophenotype: A report of 7 cases

open access: yesCytometry Part B: Clinical Cytometry, EarlyView.
Abstract Distinguishing T‐cell from NK‐cell neoplasms can occasionally be challenging, as neoplastic T cells can lose T‐cell markers such as surface CD3 (sCD3) and CD5 while acquiring NK‐cell markers such as CD16, CD56, and CD94. In this study, we present a series of 7 mature T‐cell lymphoma/leukemia cases with NK‐like immunophenotypes to clarify ...

Donor and host coexpressing KIR ligands promote NK education after allogeneic hematopoietic stem cell transplantation

open access: yesBlood Advances, 2019
: The rate and extent of natural killer (NK)–cell education after hematopoietic cell transplantation correlates with leukemia control. To study the effect of donor and host HLA on NK-cell reconstitution, single killer-cell immunoglobulin-like receptor ...

Low CD4+ T cell counts among African HIV-1 infected subjects with group B KIR haplotypes in the absence of specific inhibitory KIR ligands. [PDF]

open access: yesPLoS ONE, 2011
Natural killer (NK) cells are regulated by interactions between polymorphic killer immunoglobulin-like receptors (KIR) and human leukocyte antigens (HLA).

Evidence that neuronal G-protein-gated inwardly rectifying K+ channels are activated by Gβγ subunits and function as heteromultimers [PDF]

open access: yes, 1995
Guanine nucleotide-binding proteins (G proteins) activate K+ conductances in cardiac atrial cells to slow heart rate and in neurons to decrease excitability. cDNAs encoding three isoforms of a G-protein-coupled, inwardly rectifying K+ channel (GIRK) have

Altered distribution of mucosal NK cells during HIV infection. [PDF]

open access: yes, 2012
The human gut mucosa is a major site of human immunodeficiency virus (HIV) infection and infection-associated pathogenesis. Increasing evidence shows that natural killer (NK) cells have an important role in control of HIV infection, but the mechanism(s ...
