Chemoattraction of human blood T lymphocytes by interleukin-15

The Influence of Perforin Expression on the Sensitivity of LAK/NK Killing Against Various Tumor Target Cells

Background: Perforin is known to be important in cytolytic activity mediated by natural killer (NK) cells.   Objective: To study the relationship between the efficiency of NK and lymphokine-activated killer (LAK) cells activity, and the expression of perforin and HLA class I molecules.   Methods: LAK cells were generated by in vitro culturing of human peripheral blood lymphocytes (PBLs) in the ...

Increased Response of Human T-Lymphocytes by Dendritic Cells Pulsed with HPV16E7 and Pleurotus sajor-caju-β-glucan (PBG)

Effects of 35 Hz, 2 mT Magnetic Field on Peripheral Blood Lymphocytes of Human In Vitro and Rat In Vivo

In this research we have studied the effects of extremely low frequency magnetic field on the peripheral blood lymphocytes chromosomes of human in vitro and rat in vivo. By this means, we used 60 blood samples of 10 men as well as 40 rats. Of 60 human blood samples ,40 samples (in two group of 20) were selected as test groups and placed into the 2 mT and 35 Hz magnetic field. The blood samples,...

Up-regulation of inhibitory natural killer receptors CD94/NKG2A with suppressed intracellular perforin expression of tumor-infiltrating CD8+ T lymphocytes in human cervical carcinoma.

Inhibitory signals that govern the cytolytic functions of CD8(+) T lymphocytes have been linked to the expression of natural killer cell receptors (NKRs) on CTLs. There is limited knowledge about the induction of inhibitory NKR (iNKR) expression in vivo. Up-regulation of iNKRs has been linked to the modulation of the virus- and/or tumor-specific immune responses in animal models. In the present...

Effects of social stress on pain behavior, immune cells and serum concentrations of TNF-α, Interleukin-1 and Interleukin-6 in female mice

Introduction: Based on human studies, inequality and social injustice have adverse effects on the individual and community health. In this study, the effects of food intake inequality and social status changes on pain perception and immunological factors were investigated in Balb/C mice. Methods: The present study was conducted by implementing different social stresses including food depriva...
