We have recently shown that the use of allogeneic granulocyte colony-stimulating factor (G-CSF)-mobilized peripheral blood hematopoietic stem cell transplantation (PBHSCT), as compared with bone marrow transplantation (BMT), is associated with increased titers of antibodies (Abs) directed against red blood cell ABO antigens. To further evaluate the influence of a G-CSF-mobilized PBHSCT graft on...
PAR proteins play roles in the establishment and maintenance of polarity in many different cell types in metazoans. In C. elegans, polarity established in the one-cell embryo determines the anteroposterior axis of the developing animal and is essential to set the identities of the early blastomeres. PAR-1 and PAR-2 colocalize at the posterior cortex of the embryo. PAR-3, PAR-6 and PKC-3 (aPKC) ...
BACKGROUND Histocompatibility testing (HT) which includes donor-recipient human leukocyte antigen (HLA) matching, cross-match testing (XMT) and anti-HLA antibody searching are crucial examinations in solid organ transplantation aiming to avoid the hyperacute graft rejection and also to predict the immunological outcome of the graft. AIMS The aim of this study was to analyse the tissue typing ...
Abstract In artificial multi-agent systems, the ability to learn collaborative policies is predicated upon agents’ communication skills: they must be able encode information received from environment and how share it with other agents as required by task at hand. We present a deep reinforcement learning approach, Connectivity Driven Communication (CDC), that facilitates emergence of behaviour o...
Two patients with Hodgkin's disease in remission and one chronic lymphatic leukemia patient with extraordinarily high anti-Epstein-Barr virus (EBV) (viral capsid antigen) antibody titers (greater than 10,000) were selected to study a spectrum of cell-mediated immune responses, including natural killer, interferon-boosted killer, antibody-dependent lymphocytotoxicity, and T-cell-mediated reactio...
A diminished chemotactic response was observed with the neutrophils of a patient with the Chediak-Higashi syndrome, who was not in the accelerated phase of the disease. An abnormally low release of myeloperoxidase from these cells during phagocytosis was also noted; this resulted in a decreased iodination capacity and probably also caused the defect in the intracellular killing of bacteria by t...
Finding factors that control complement (C) components deposition on bacterial cells is the way to explain the sophisticated mechanism of bacteraemia. Lipopolysaccharide (LPS, endotoxin) is a surface antigen found in the cell walls of Gram-negative bacteria, such as Salmonella [1]. LPS action on the human body is often considered in the context of sepsis, which is characterized by an excessive ...
Cdc25 phosphatases are key positive cell cycle regulators that coordinate cell divisions with growth and morphogenesis in many organisms. Intriguingly in C. elegans, two cdc-25.1(gf) mutations induce tissue-specific and temporally restricted hyperplasia in the embryonic intestinal lineage, despite stabilization of the mutant CDC-25.1 protein in every blastomere. We investigated the molecular ba...
