Acquisition of T cell responses during primary CMV infection in lung transplant recipients (LTRs) appear critical for host defense and allograft durability, with increased mortality in donor+/recipient- (D+R-) individuals. In 15 D+R- LTRs studied, acute primary CMV infection was characterized by viremia in the presence or absence of pneumonitis, with viral loads higher in the lung airways/allog...
Cytomegalovirus (CMV) is a major threat in patients undergoing allogeneic bone marrow transplantation. The adoptive transfer of CMV-specific cytotoxic T lymphocytes (CTLs) expanded from the blood of CMV-seropositive donors has been shown to effectively control CMV infection. However, the requirement for safe and effective antigen-presenting cells (APCs) for each patient precludes broad applicab...
Thirty renal transplant recipients, after transplantation, were tested weekly with the following assays: cytomegalovirus (CMV) antigenemia (pp65 Ag), plasma qualitative Amplicor CMV (P-AMP), plasma and peripheral blood leukocyte quantitative Amplicor CMV monitor (P- and PBL-CMM), peripheral blood leukocyte (PBL) quantitative Quantiplex bDNA CMV, version 2.0 (bDNA), and whole-blood Nuclisens pp6...
Alzheimer's disease (AD) has been associated with increased local inflammation in the affected brain regions, and in some studies also with elevated levels of proinflammatory cytokines in peripheral blood. Cytomegalovirus (CMV) is known to promote a more effector-oriented phenotype in the T-cell compartment, increasing with age. The aim of this study was to investigate the inflammatory response...
We compared the CMV Brite Turbo Kit (BT) and the Digene Hybrid Capture CMV DNA (version 2.0) assay (HC2) in the quantitation of pp65 antigenemia and cytomegalovirus (CMV) DNA levels in immunosuppressed renal transplant recipients. Of 123 blood specimens collected from 24 renal transplant recipients, BT and HC2 assays detected 35 and 39 positive samples, respectively. The overall concordance rat...
BACKGROUND In healthy, HIV seronegative, CMV seropositive adults, a large proportion of T cells are CMV-specific. High-level CMV-specific T cell responses are associated with accelerated immunologic aging ("immunosenesence") in the elderly population. The impact of untreated and treated HIV infection on the frequency of these cells remains undefined. METHODOLOGY/PRINCIPAL FINDINGS We measured...
Lactobacilli have been shown to promote health functions. In this study, we analyzed the mechanism by which four different strains of probiotics affected innate immunity, such as regulation of ROS, cytokines, phagocytosis, bactericidal activity, signaling by NF-κB pp65, and TLR2 activation. The production of ROS was dependent on the concentration and species of Lactobacillus. The results obtain...
Gliomas are the most common primary central nervous system (CNS) neoplasms in humans. Human cytomegalovirus (HCMV) has been described to be associated with gliomas, though the exact mechanisms of HCMV in oncogenesis are unclear. In this study, the investigation of detecting HCMV in the tumor tissues and peripheral blood of patients with newly diagnosed gliomas were performed to enrich medical k...
Previous studies showed that human cytomegalovirus (HCMV) is associated with atherosclerosis. However, local vascular atherosclerosis related HCMV infection and protein expression remain unclear. This study aimed to assess the relationship between HCMV infection and atherosclerosis. Formalin-fixed, paraffin-embedded peripheral artery specimens were obtained from 15 patients with atherosclerosis...
