Natural Killer Cell Responses during Human ?-Herpesvirus Infections

نویسندگان

چکیده

Herpesviruses are main sculptors of natural killer (NK) cell repertoires. While the ?-herpesvirus human cytomegalovirus (CMV) drives accumulation adaptive NKG2C-positive NK cells, ?-herpesvirus Epstein–Barr virus (EBV) expands early differentiated NKG2A-positive cells. cells support immunity by antibody-dependent cellular cytotoxicity, seem to preferentially target lytic EBV replicating B The importance this restriction replication during pathogenesis will be discussed. Furthermore, modification EBV-driven expansion coinfections, including other Kaposi sarcoma-associated herpesvirus (KSHV), summarized.

Natural killer cells in herpesvirus infections

Natural killer (NK) cells are potent innate cytotoxic lymphocytes for the destruction of infected and transformed cells. Although they were originally considered to be ready-made assassins after their hematopoietic development, it has recently become clear that their activity is regulated by mechanisms such as repertoire composition, licensing, priming, and adaptive memory-like differentiation....

Natural killer cell responses to infections in early life.

Natural killer (NK) cells are an important component of innate immune responses to infectious diseases. They mediate protection by being able to rapidly lyse infected cells and produce cytokines (primarily interferon-γ) that shape innate and adaptive immune responses. This review summarizes current knowledge on the phenotype and functional abilities of NK cells from healthy newborns/infants and...

Natural killer cell functional defects in pediatric patients with severe and recurrent herpesvirus infections.

Natural killer (NK) cells play a critical role in the host defense against herpesviruses. Although herpesviruses are ubiquitous in human populations, only a minority of people experience severe recurrent infections. We hypothesize that uncharacterized NK cell functional deficits predispose individuals to more significant or frequent herpesvirus infections and reactivations. To investigate this ...

The Interplay between Natural Killer Cells and Human Herpesvirus-6

Human Herpesvirus 6 (HHV-6) is a set of two closely related herpes viruses known as HHV-6A and HHV-6B. Both are lymphotropic viruses that establish latency in the host. The ability to evade the immune responses of effector cells is likely a major factor contributing to the development of a persistent HHV-6A/B (collectively termed HHV-6) infection. Natural killer (NK) cells are lymphocytes that,...

Natural killer cell responses to viral infection.

Natural killer (NK) cells, as part of the innate immune system, play a key role in host defense against viral infections. Recent advances have indicated that NK cell activation and function are regulated by the interplay between inhibitory and activating signals. Thus, a better understanding of mechanisms responsible for NK cell activation and function in the control of viral infections will he...
