Abstract: Chronic inflammatory states lead to T cell exhaustion, characterized by reduced T cell proliferation and activity. Immune checkpoint inhibitors (ICPI) reactivate T cells to restore the immune system’s natural defenses against foreign antigens. The widespread use of these agents in the treatment of m [...]

Abstract: The privileged liver by its immunological status is described as a tolerogenic organ. However, these alone do not explain the installation of a tolerance after single or combined liver transplantation (kidney, heart, pancreas, intestine). Other factors appear to be involved in the identification of [...]

Abstract: Background: Cardiac allograft vasculopathy (CAV) remains a major obstacle to long-term heart allograft survival. A number of studies show that immune mechanisms involved in CAV. Using non-invasive cellular MRI (CMRI) to explore indicators of CAV lesions and characterize its development could provi [...]

Abstract: Background: Estradiol 17-beta (E2) enhances the function and survival of pancreatic beta-cells but its clinical use has been questioned due to concerns regarding oncogenic potential and feminizing effects in males. The G-protein coupled estrogen receptor (GPER), expressed in pancreatic islets, exhib [...]

Abstract: Hematopoietic stem cell transplant (HSCT) recipients are at an increased risk of bacterial, viral, fungal and parasitic infections. Past exposures to infections, the degree of immunosuppression, prolonged neutropenia and presence of graft versus host disease (GVHD) are some of the factors which make [...]

Abstract: Background: The application of hematopoietic cell transplantation for induction of immune tolerance has been limited by toxicities associated with conditioning regimens and to graft-versus-host disease (GVHD). Decades of animal studies have culminated into sufficient control of these two problems, m [...]

Abstract: Background - T follicular helper (Tfh) and regulatory (Tfr) cells are key players in the formation of long-lived antibody responses. Their circulating counterparts, cTfh and cTfr, are often used as biomarkers because longitudinal sampling of secondary lymphoid tissues is unfeasible in clinical studi [...]

Abstract: Background: Cell encapsulation technology is most likely the ultimate solution for autologous cell therapy based clinical approaches. A key issue when developing a functional encapsulated construct, is to consider not only the nature of the capsule but also how the cells should be incorporated into [...]

Abstract: Purpose: to estimate the survival of patients in a heart transplantation waiting list (HTxWL) at V.A.Almazov NMRC from 2010 to 2017 and to define risk factors for death among these patients. Materials and methods: A single-centre retrospective study of 151 patients with advanced chronic heart failur [...]

Abstract: Hematopoietic cell transplantation is frequently complicated by infectious disease-related complications, especially pneumonia. Candida and enterococci are often overlooked as pulmonary pathogens with some clinicians firmly believing that these organisms never cause pneumonia. Here, we present a ser [...]
