The incidence of obesity, as a major health problem, has increased significantly over the past decades. This condition is associated with an increased risk of cancers, type 2 diabetes, and cardiovascular diseases. The current study aimed to investigate the effects of inflammation and changes of adipose tissue-resident immune cells on increasing the risk of cancer in obese individuals. In obesit...
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 ...
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.
Background: Pregnancy is a phenomenon that antigens of semi allogenic fetus are in direct contact with mother's immune system. Immune dysregulation can cause fetus rejection by mother's immune system responses. Human leukocyte antigen-G1, as an immunotolerant molecule has a major role to induce tolerance during pregnancy by suppression of natural killer cells through inhibitor receptors on thes...
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: uterine natural killer (unk) cells are the most abundant leukocytes in pre-implantation endometrium and early pregnancy deciduas in humans and rodents. they are associated with structural changes in maternal spiral arteries but regulation of their re-cruitment and activation is incompletely understood. the major subpopulation of unk cells in humans expresses cd56, the neural cell ad...
Tumor cells, like most other release exosomes called tumor-derived (TEX) and are vital for intercellular communication. TEX membrane-bound extracellular vesicles (EVs), containing unique cargo reminiscent of the parent tumor cells possess immunomodulatory functions. carries factors that directly promote immunosuppression in microenvironment indirectly attract immunosuppressive T-regulatory (Tre...
Background: Uterine natural killer (uNK) cells are the most abundant leukocytes in pre-implantation endometrium and early pregnancy deciduas in humans and rodents. They are associated with structural changes in maternal spiral arteries but regulation of their re-cruitment and activation is incompletely understood. The major subpopulation of uNK cells in humans expresses CD56, the neural cell ad...
background: pregnancy is one of the changer agents for defensive cells, however it is unknown the effect of the ethanolic extract of the salvia officinalis on the uterine natural killer cells population in the pregnant mice that needs to be investigated. objective: the aim of this study was to determine the effect of the ethanolic extract of the salvia officinalis on the uterine natural killer ...
