The effects of the human and bovine LSF (derived from sera) as well as their purified fractions were studied on murine lymphocytes reactions indicated by blast transformation (BT) assay, mixed lymphocyte culture (MLC) and IgG synthesis. The results indicated that bovine lipid suppressor factor (LSF) has significant immunosuppressive activity on lymphocytes proliferation both in BT and MLC ...
Background: Protozoa are unicellular eukaryotes. A type of intestinal protozoan pathogens is the cause of infection and serious injuries in human with or without clinical symptoms. It seems that parasitic infections as a stressor factor can affect on stress system activity and immune system function and sensitivity. The major purpose of this paper was to evaluate serum cortisol level and the ge...
The effect of purified glycosphingolipids from Leishmania (Leishmania) amazonensis on human lymphoproliferation, on expression of human lymphocyte and monocyte markers (CD3, CD4, CD8, CD14, CD19, and CD45), and on lymphocyte protein kinase C activity was analyzed.
backgrounds: seminoma is frequently observed in human and canine testes especially in cryptorchids. canine and human seminomas are typically associated with leukocytic infiltration. objectives: we aimed to identify the type of lymphocytes that infiltrate to seminomas. methods: tumor infiltrating lymphocytes were evaluated by immunohistological techniques in 5 dogs with diffuse seminoma. routine...
Structural, functional and immunological similarities between the ninth component of complement (C9) and the lymphocyte pore-forming protein (PFP, perforin) have recently been described (8-10). PFP is shown here to be immunologically related to all other components of the membrane attack complex (MAC) of human complement, namely, C5b-6, C7, C8, and C9. Polyclonal antibodies raised against purif...
Introduction: Medicinal plants, such as flaxseeds play an important role in the health of individuals and communities. Regarding the phytochemical properties of flaxseed, this study aimed to investigate the hydroalcoholic effects of this plant on the genetic toxicity of cyclophosphamide in peripheral blood lymphocytes. Materials & Methods: The flaxseed extract was initially prepared by macer...
Equine immunoglobulin was detected along the glomerular basement membrane of three human homograft recipients who had been treated with equine anti-lymphocyte globulin. Anti-lymphocyte globulins, given these patients, were obtained by immunization of horses with lymphocytes from human spleens and/or lymph nodes and contained glomerular basement membrane-reactive antibodies. Quantitative paired-...
The capacity of retinoic acid to modulate human T-lymphocyte and B-lymphocyte activation by mitogens was examined. T-lymphocyte proliferation stimulated by 12-O-tetradecanoylphorbol-13-acetate (TPA) or phytohemagglutinin was enhanced by 5 nM to 5 microM retinoic acid in a dose-dependent manner with a 65 +/- 35% (SD) increase (n = 6, P less than 0.01) in TPA-stimulated proliferation induced by 5...
