background: apoptosis is a process that plays an important role during early stage of implantation. the aim of this study was to investigate the incidence of apoptosis in mice endometrium after ovarian stimulation at implantation period. methods: nmri female mice were divided into two groups: 1) control group, which were rendered pseudopregnant by vaginal stimulation and 2) experimental group, ...
schizophrenia (scz) is a complex disorder with no clarified etiology or biological diagnosis. symptoms of schizophrenia including positive, negative and cognitive deficits.the neurodegenrative and neurodevelopmental hypothesis are main views about the pathophysiology of schizophrenia. neuregulin 1 is one of four proteins in the neuregulin family that act on the egfr family of receptors. nrg1 ...

objective(s): streptococcus pyogenes produces extracellular hyaluronidase enzyme. this enzyme is directly associated with the spread of the organism during infection. the objective of the present study was to clone and express the nucleotide sequence of the enzyme which is involved in hyaluronidase enzymatic activity. materials and methods: the enzymatic region of hyaluronidase gene was detecte...
antimicrobial peptide brevinin-2r induces the secretion of a pro-inflammatory cytokine in hepg2 cells
introduction: antimicrobial peptides as the body's defense strategy play an important role in resistance against infection of microorganism. these peptides are able to modulate the immune and inflammatory processes through the production of defensive molecules. therefore, the modulatory effects of brevinin-2r, an antimicrobial peptide extracted from the skin of the frog (rana ridibunda), w...
Mast cells (MCs), recognized as tissue-resident cells of hematopoietic origin, are involved in cellular and pathological manifestations of allergic disorders including atopic dermatitis. IL-33, a member of the IL-1 cytokine family, activates Th2-type immune responses, and promotes the degranulation and maturation of MCs. However, it is uncertain whether IL-33 treatment induces mature mast cells...
ژن tlr4 بر روی کروموزوم 17 قرار گرفته و دارای 3 اگزون و 2 اینترون است. این ژن باعث سنتز پروتئینی با تعداد843 اسید آمینه می شود که تنظیم و شروع کننده یپاسخ های ایمنی به هنگام آلودگی با باکتری های گرم منفی است. هدف از این مطالعه تجزیه و تحلیل ساختاری ژن tlr4 و ارتباط آن با صفات ایمنی در دو سویه بومی و تجاری بود. برخی از صفات ایمنی مثل میزان عیار پادتن های تولید شده علیه srbc (عیار پادتن کل، ta؛ ع...
background: ovarian tissue cryopreservation is an alternative strategy to preserve the fertility of women predicted to undergo premature ovarian failure. this study was designed to evaluate the expression of folliculogenesis-related genes, including factor in the germline alpha (figla), growth differentiation factor-9 (gdf-9), follicle-stimulating hormone receptor (fshr), and kit ligand after v...
MHC class II (MHCII) deficiency or bare lymphocyte syndrome (BLS) is a severe immunodeficiency characterized by deficient T helper (Th)-cell-dependent immunity. The disease is caused by defects of the MHCII promoter complex resulting in low or absent MHCII expression. We demonstrate in a murine model of MHCII deficiency (RFX5- or CIITA-deficient mice) that residual MHCII expression by professio...
Expression of class II transactivator (CIITA), the transcriptional regulator that controls all class II expression, is controlled in cell lines in vitro by three promoters: the dendritic cell promoter PI, the B cell promoter PIII, and the interferon-gamma (IFN-gamma)-inducible promoter, PIV. The authors examined the promoter usage in vivo in mouse kidney in the basal state and in response to IF...
