Natural killer (NK) cells are innate lymphocytes that lack antigen-specific rearranged receptors, a hallmark of adaptive lymphocytes. In some people infected with human cytomegalovirus (HCMV), an NK cell subset expressing the activating receptor NKG2C undergoes clonal-like expansion that partially resembles anti-viral adaptive responses. However, the viral ligand that drives the activation and differentiation of adaptive NKG2C+ NK cells has remained unclear. Here we found that adaptive NKG2C…

Cytomegalovirus Infection Drives Avidity Selection of Natural Killer Cells.

Biology and Clinical Relevance of HCMV-Associated Adaptive NK Cells

The expansion of adaptive NK cells in vivo has been documented in various viral infections, while the frequency of adaptiveNK cells among peripheral blood mononuclear cells correlates with improved prognosis of monoclonal Ab treatment against leukemia.

Natural killer cell specificity for viral infections

The numerous modes for the specific recognition of viral antigens and peptides by NK cells and the implications of this for the composition of the NK cell repertoire as well as for the the selection of viral variants are discussed.

NK Cell-Mediated Recall Responses: Memory-Like, Adaptive, or Antigen-Specific?

These exciting findings not only support the idea of NK cells with adaptive features, but define a novel field of harnessing memory NK cell subsets for therapeutic strategies.

Phenotypic and Functional Characteristics of a Novel Influenza Virus Hemagglutinin-Specific Memory NK Cell

A novel hemagglutinin (HA)-specific NKp46+ NKG2A+ NK cell subset induced by influenza A virus infection bridges innate and adaptive immune memory response and promotes the homeostasis of local environment during recall response.

NK Cell Memory to Cytomegalovirus: Implications for Vaccine Development

Current understanding of NK cell memory to viral infection with a focus on the response to cytomegaloviruses is discussed with particular emphasis on how a strategy that can harness the innate immune system and NK cells could be crucial for the development of a vaccine against this high-priority pathogen.

Impact of CMV Infection on Natural Killer Cell Clonal Repertoire in CMV-Naïve Rhesus Macaques

It is suggested that RhCMV is not the sole driver of clonal expansion and peripheral maintenance of mature NK cells; however, infection of macaques with this herpesvirus does result in selective expansion and persistence of specific NK cell clones, providing further information relevant to adaptive NK cells and the development of NK cell therapies.

Human CD8+ T-Cell Populations That Express Natural Killer Receptors

The current knowledge of various CD8+ T- cell populations expressing NK receptors is reviewed to pave the way for delineating the landscape and identifying the various roles of these T-cell populations.

The Direct Influence of Cytomegalovirus Lysate on the Natural Killer Cell Receptor Repertoire.

CMV may drive a direct influence on NK cell receptor repertoire, including the expansion of NK cells expressing NKG2C receptor, which is needed for further studies.

Expansion of a unique CD57+NKG2Chi natural killer cell subset during acute human cytomegalovirus infection

The preferential expansion of a unique subset of NK cells coexpressing the activating CD94–NKG2C receptor and CD57 in CMV+ donors is demonstrated and it is proposed that CD57 might provide a marker of “memory” NK cells that have been expanded in response to infection.

NK cell responses to cytomegalovirus infection lead to stable imprints in the human KIR repertoire and involve activating KIRs.

The results provide new insight into the diversity of KIR repertoire and its adaptation to virus infection, suggesting a role for both activating and inhibitory KIRs in immunity to CMV infection.

Cytomegalovirus infection drives adaptive epigenetic diversification of NK cells with altered signaling and effector function.

Expansion of CD94/NKG2C+ NK cells in response to human cytomegalovirus-infected fibroblasts.

The data support that the interaction of CD94/NKG2C with HCMV-infected fibroblasts, concomitant to the inhibition of human leukocyte antigen (HLA) class I expression, promotes an outgrowth of CD 94/NKg2C(+) NK cells.

Cytomegalovirus-Infected Primary Endothelial Cells Trigger NKG2C+ Natural Killer Cells

A cell-dependent modulation of HLA-E expression by CMV infection is demonstrated by comparing HLA expression patterns in CMV-infected EC, fibroblasts and MDDC, and it is demonstrated that NKG2C+ NK cell degranulation was significantly triggered byCMV- Infected EC regardless of the nature of the Hla-E allele product.

IL-12-producing monocytes and HLA-E control HCMV-driven NKG2C+ NK cell expansion.

Together, the results reveal that IL-12, CD14(+) cells, and the CD94/NKG2C/HLA-E axis are critical for the expansion of NKG 2C(+) NK cells in response to HCMV infection.

Cytomegalovirus reactivation after allogeneic transplantation promotes a lasting increase in educated NKG2C+ natural killer cells with potent function.

The kinetics of the NK-cell response to CMV reactivation in human recipients after hematopoietic cell transplantation is characterized to support the emerging concept that CMV-induced innate memory-cell populations may contribute to malignant disease relapse protection and infectious disease control long after transplantation.

CMV drives clonal expansion of NKG2C+ NK cells expressing self‐specific KIRs in chronic hepatitis patients

It is shown that HCMV seropositivity was associated with a profound expansion of NKG2C+CD56dim NK cells in patients with chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) infection, shedding new light on how the human NK‐cell compartment adjusts to HCMv infection.

UL40-mediated NK evasion during productive infection with human cytomegalovirus

It is demonstrated that HCMV encodes a mechanism of evasion specifically targeted against a proportion of CD94+ NK cells and show that this system functions during a productive infection.
