BACKGROUND AND AIMS There is growing evidence of the effects of immunosuppressive agents on "immune targets" in renal transplantation. Immunological monitoring could indirectly measure the suppressive effect of these drugs and guide early preventive interventions in transplant recipients. Due to the selective antiproliferative effect of mycophenolate mofetil (MMF) on lymphocytes, our goal was t...

The relationship between tumour load and immunity in gastrointestinal cancer has been studied by sequential comparison in patients whose tumour has been removed and those whose tumour was found to be inoperable. Total lymphocyte count, absolute and percentage T- and B-lymphocyte counts, effect of papain on E-rosetting cell levels, and inhibitory effect of cancer sera on E-rosette formation by n...

A marked suppression of the thymusderived (T)-lymphocyte response to concanavalin A has been demonstrated in vitro during renal infection. Suppression of the T-lymphocyte response in vitro was seen as early as 2 h after the induction of renal infection, but maximum suppression was found 24-72 h later. A population of suppressor cells in the splenic lymphocyte population, generated during the ho...

Background: Low vitamin D has been linked to enhance inflammatory markers in various pathological conditions. We aimed to evaluate the urinary tract infection (UTI)-associated hematological and inflammatory markers mediated by low serum levels of 25-hydroxyvitamin D [25(OH)D]. Methods: Vitamin D level, hematological indices (Neutrophil-to-lymphocyte ratio [NLR], Monocyte-to-lymphocyte ratio [M...

Adoptive immunotherapy with donor lymphocyte infusions (DLI) is an effective treatment for relapsed chronic myeloid leukemia (CML) after allogeneic stem cell transplantation. To identify the effector and target cell populations responsible for the elimination of the leukemic cells in vivo we developed an assay to measure the frequency of T lymphocyte precursor cells capable of suppressing leuke...

INTRODUCTION Gene therapy could prevent bleeding in hemophilia. However, antibodies could inhibit coagulation, while cytotoxic T lymphocytes could destroy modified cells. The immaturity of the newborn immune system might prevent these immune responses from occurring after neonatal gene therapy. MATERIALS AND METHODS Newborn dogs, cats, or mice were injected intravenously with a retroviral vec...

Objective: Hematological parameters including neutrophil–lymphocyte ratio (NLR), platelet–lymphocyte (PLR), and monocyte–lymphocyte (MLR) have been demonstrated as new predictors of prognosis activity in various diseases. In this study, we aimed to investigate the associations NLR, PLR MLR with disease severity patients anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitis (AAV). &#...

The present studies were designed to examine the effects of ribavirin (1-beta-D-ribofuranosyl-1,2,4-triazole-3-carboxamide), a broad-spectrum antiviral agent, on the generation of murine antibody responses in vitro. Whereas primary and secondary sheep erythrocyte-specific, plaque-forming cell responses by normal murine spleen cells were enhanced by low concentrations of ribavirin (1 microgram p...

In response to a given stimulus, usually a number of cytokines are secreted simultaneously by the immune system. Whether these cytokines are meant to function as a single agent or in combination with others is not understood. Tumor necrosis factor (TNF) has been shown to exhibit antiproliferative effects against a wide variety of tumor cell lines in vitro. In the present report, we investigated...
