Investigation of the KIR-status of patients with head and neck squamous-cell carcinoma in bloodserum
Introduction The activation of natural killer cells (NK) by their KIR (killer cell immunoglobulin-like receptor) is a potent defense system tumor cells. In this thesis we want to investigate the profile 16 inhibiting and activating KIRs in bloodserum patients with head neck squamous-cell carcinoma (HNSCC). Furthermore, calculate correlation between KIR-status overall survival (OS) HNSCC-patients.
Natural killer cells are the key components in tumor immunity and defects in function are necessary for tumor immune escape. Emerging studies on tumor cell-derived exosomes have shown the biological significance in tumor microenvironment, but the underlying role of exosomes in regulating natural killer cells functions in clear cell renal cell carcinoma patients remains unknown. Firstly, we prec...
Background: Non-Hodgkin lymphoma (NHL) involvement of the uterus is rare. Histologically, the majority of previously reported cases of NHL involving the female genital tract have been aggressive B-cell lymphomas, while natural killer (NK)/T-cell lymphoma involving the uterus is extremely rare. Case presentation: We report a case of primary cervical extranasal NK/T-cell lymphoma in a 36-year-old...
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...
Recent major antibody deals involve immune checkpoint inhibitors, antibody–drug conjugates and natural killer cell engagers for cancer.
In normal human peripheral blood, cutaneous lymphocyte antigen is expressed by memory T cells, suggesting a specific tissue-homing population of T cells. In this study it is demonstrated that 6% of CD56 + natural killer cells in peripheral blood also express cutaneous lymphocyte antigen (CLA). It was also detected that most of the tumor cells in primary cutaneous nasal-type natural killer cell ...
In vitro irradiation with long wavelength ultraviolet light (UV-A), in clinically relevant dosages, of a natural killer cell line containing cell preparations from 17 control subjects reduced natural killer cell cytotoxicity with the cell line K562 as target. The spontaneous function of natural killer cells from 12 patients with systemic lupus erythematosus (SLE) correlated inversely with the o...
Women with chronic hypertension are at increased risk of maternal and fetal morbidity and mortality. We have previously characterized the stroke-prone spontaneously hypertensive rat (SHRSP) as a model of deficient uterine artery function and adverse pregnancy outcome compared with the control Wistar-Kyoto. The activation of the immune system plays a role in hypertension and adverse pregnancy ou...
Invariant natural killer T cells have a distinct developmental pathway from conventional αβ T cells. Here we demonstrate that the transcriptional repressor NKAP is required for invariant natural killer T cell but not conventional T cell development. In CD4-cre NKAP conditional knockout mice, invariant natural killer T cell development is blocked at the double-positive stage. This cell-intrinsic...
Pre-eclampsia, fetal growth restriction and stillbirth are major pregnancy disorders throughout the world. The underlying pathogenesis of these diseases is defective placentation characterized by inadequate invasion of extravillous placental trophoblast cells into the uterine arteries. How trophoblast invasion is controlled remains an unanswered question but is influenced by maternal uterine im...
