Natural killer cell receptor signaling.
Natural killer (NK) cell immune responses are regulated by a balance of activating and inhibitory signals transmitted by cell surface receptors. Immunoreceptor tyrosine-based inhibition motifs in the cytoplasmic domains of inhibitory NK receptors recruit tyrosine or lipid phosphatases, which modulate the activation signals transmitted by receptors linked to the Syk and ZAP70 tyrosine kinases an...
متن کاملPrimary cutaneous blastic natural killer cell lymphoma.
Sir, Blastic natural killer-cell lymphoma, also called “agranular CD4+ CD56+ haematodermic neoplasm” is an uncommon type of tumour, which is included in the new World Health Organization (WHO) classification as a malignancy derived from natural killer (NK) cells. It is very aggressive, affecting many organs, and skin involvement is highly characteristic. Several origins have been proposed, but ...
متن کاملNatural killer cell deficiency.
Natural killer (NK) cells are part of the innate immune defense against infection and cancer and are especially useful in combating certain viral pathogens. The utility of NK cells in human health has been underscored by a growing number of persons who are deficient in NK cells and/or their functions. This can be in the context of a broader genetically defined congenital immunodeficiency, of wh...
متن کاملNatural killer cell neoplasms.
Lymphoid neoplasms that are derived from natural killer (NK) cells are uncommon but distinct clinicopathologic disease entities. Three types have been recognized and categorized in the latest World Health Organization classification: extranodal NK cell lymphoma, nasal-type; aggressive NK cell leukemia; and blastic NK cell lymphoma. All NK tumor cells express the NK cell marker CD56, but they la...
متن کاملHyperthermia Increases Natural Killer Cell Cytotoxicity against SW-872 Liposarcoma Cell Line
Background: Although there is convincing data in support of the effectiveness of hyperthermia in tumor therapy, the molecular mechanisms underlying the clinical effects of hyperthermia are still poorly understood. Objective: To investigate natural killer (NK) cell cytotoxicity against heat-treated SW-872 and HeLa tumor cell lines. Methods: NKG2D ligands and HLA class I transcription were examin...
