Baseline and dynamic expression of activating NK cell receptors in the control of chronic viral infections: the paradigm of HIV-1 and HCV.

open access: yesFrontiers in Immunology, 2014
Natural Killer cell function is regulated by a balance between activating and inhibitory receptors expressed on their surface. .A relevant effort has focused so far on the study of KIR carriage/expression setting the basis for NK cell education and self ...

Higher expression of activating receptors on cytotoxic NK cells is associated with early control on HIV-1 C multiplication

open access: yesFrontiers in Immunology, 2014
Natural killer (NK) cells may be important in modulating HIV replication in early course of HIV infection. The effector function of NK cells is finely tuned by a balance between signals delivered by activating and inhibitory receptors.

Protease Activated Receptors and Arthritis [PDF]

open access: yesInternational Journal of Molecular Sciences, 2021
The catabolic and destructive activity of serine proteases in arthritic joints is well known; however, these enzymes can also signal pain and inflammation in joints. For example, thrombin, trypsin, tryptase, and neutrophil elastase cleave the extracellular N-terminus of a family of G protein-coupled receptors and the remaining tethered ligand sequence ...

The early days of NK cells: An example of how a phenomenon led to detection of a novel immune receptor system

open access: yesFrontiers in Immunology, 2014
In this review I summarize some of the early research on NK cell biology and function that led to the discovery of a totally new receptor system for polymorphic MHC class I molecules.

The modulation of the cell cycle: a sentinel to alert the NK cells of dangers

open access: yesFrontiers in Immunology, 2013
Natural killer (NK) cells are an essential component of innate immunity that provides a rapid response to detect stressed, infected, or transformed target cells. This system is controlled by a balance of inhibitory and activating signals transmitted by a

Inhibitory Receptor Crosslinking Quantitatively Dampens Calcium Flux Induced by Activating Receptor Triggering in NK Cells

open access: yesFrontiers in Immunology, 2019
Natural killer (NK) cell function is regulated by a balance between activating and inhibitory receptors, but the details of this receptor interplay are not extensively understood.

Human NK Cells and Herpesviruses: Mechanisms of Recognition, Response and Adaptation

open access: yesFrontiers in Microbiology, 2019
NK cells contribute to early defenses against viruses through their inborn abilities that include sensing of PAMPs and inflammatory signals such as cytokines or chemokines, recognition, and killing of infected cells through activating surface receptors ...

Evolution of visual guanylyl cyclases and their activating proteins with respect to clade and species-specific visual system adaptation

open access: yesFrontiers in Molecular Neuroscience, 2023
Membrane guanylyl cyclase receptors are important regulators of local cGMP production, critically influencing cell growth and differentiation as well as ion transport, blood pressure and calcium feedback of vertebrate phototransduction.

Expression of ligands for activating natural killer cell receptors on cell lines commonly used to assess natural killer cell function

open access: yesBMC Immunology, 2019
Background Natural killer cell responses to virally-infected or transformed cells depend on the integration of signals received through inhibitory and activating natural killer cell receptors.

Research Progress on NK Cell Receptors and Their Signaling Pathways

open access: yesMediators of Inflammation, 2020
Natural killer cells (NK cells) play an important role in innate immunity. NK cells recognize self and nonself depending on the balance of activating receptors and inhibitory receptors. After binding to their ligands, NK cell receptors trigger subsequent
