The murine cytomegalovirus m02 gene family encodes putative type I membrane glycoproteins named m02 through m16. A subset of these genes were fused to an epitope tag and cloned into an expression vector. In transfected and murine cytomegalovirus-infected cells, m02, m04, m05, m06, m07, m09, m10, and m12 localized to cytoplasmic structures near the nucleus, whereas m08 and m13 localized to a fil...

Nearly 100 chemicals, chiefly purincs and pyrimidines and a few antibiotics, have been tested for their ability to interfere with the killing action of Paramecia and to produce sensitives from killer animals, presumably through inactivation of kappa. Kappa, a cytoplasmic factor in certain stocks of Parumecium uureliu, dependent upon, but not initiated by, the dominant allele of the killer gene,...

BACKGROUND The number of type 2 helper CD4+ T cells is increased in the airways of persons with asthma. Whether the majority of these cells are class II major-histocompatibility-complex-restricted cells or are among the recently identified CD1d-restricted invariant natural killer T cells is a matter of controversy. We studied the frequency of invariant natural killer T cells in the airways of s...

This study aimed to investigate ferroptosis-related molecular subtypes and their potential value in gastric adenocarcinoma (GAC). Gene expression associated clinical phenotype data were downloaded from TCGA database. Unsupervised clustering was performed identify suitable subtypes, followed by a correlation analysis of factors. set variation analysis, immune infiltration, differentially express...

In Neurospora crassa, pairing of homologous DNA segments is monitored during meiotic prophase I. Any genes not paired with a homolog, as well as any paired homologs of that gene, are silenced during the sexual phase by a mechanism known as meiotic silencing by unpaired DNA (MSUD). Two genes required for MSUD have been described previously: sad-1 (suppressor of ascus dominance), encoding an RNA-...

Lymphocytes from parental strain DA rats can induce potent killer cell responses to atypical antigen systems in F1 Lewis (L)/DA and DA/L recipients. Here, we describe an antigen system, H, present on homozygous parental target cells, but not on F1 cells. This antigen system is unusual in several respects: it does not involve class I RT1A gene products usually used by killer cell responses in th...

The combination of radiotherapy and immunotherapy has shown great promise in eradicating tumors. For example, 125I radioactive particle implantation and cytokine-induced killer cell therapies have demonstrated efficacy in treating hepatocellular carcinoma. However, the mechanism of this combination therapy remains unknown. In this study, we utilized cytokine-induced killer cells obtained from h...

interferon gamma (ifn-g) is a cytokine produced by activated t lymphocytes and natural killer cells. it plays an important role in innate and adaptive immunity. ifn-g gene is polymorphic and its haplotype has been associated with resistance to nematode infestations which are the most important parasites of domestic sheep worldwide. to evaluate ifn-g polymorphism in iranian shaul sheep populatio...

background: infertility is an increasing medical and social problem. in vitro fertilization (ivf) has become a common and accessible treatment for a wide variety of indications that have variable outcomes. natural killer (nk) cells have been identified as relevant immunological factors involved in reproductive success or failure. objective: the aim of this study was to compare the percentage of...

Background: HLA-G, as a tolerogenic molecule, expressed in cytotrophoblast cells and playing an important role in the suppression of the immune response in maternal decidua. Today Interaction of the extracellular domains of HLA-G protein with cell receptors of immune system, including CD8, LILRB1, LILRB2 and killer cell immunoglobulin-like receptor KIR2DL4, was well known. Materials and Methods...
