African swine fever virus (ASFV) produces a fatal acute hemorrhagic fever in domesticated pigs that potentially is a worldwide economic threat. Using an expressed sequence tag (EST) library-based antisense method of random gene inactivation and a phenotypic screen for limitation of ASFV replication

Cell death is an early and common event in the pathogenesis associated with the abnormal development induced by a variety of teratogens. Previously, we showed that the cell death induced in day 9 mouse embryos by three teratogens, hyperthermia (HS), 4-hydroperoxycyclophosphamide (4-CP), and sodium

Classical swine fever virus (CSFV) causes severe disease in pigs associated with leukopenia, haemorrhage and fever. We show that CSFV infection protects endothelial cells from apoptosis induced by the dsRNA mimic, pIpC, but not from other apoptotic stimuli, FasL or staurosporine. CSFV infection

Pathogenesis of viral haemorrhagic fevers is associated with alteration of vascular barrier function and haemorrhage. To date, the specific mechanism behind this is unknown. Programmed cell death and regulation of apoptosis in response to viral infection is an important factor for host or virus

The open reading frame EP153R of African swine fever virus (ASFV) encodes a nonessential protein that has been involved in the hemadsorption process induced in virus-infected cells. By the use of a virus deletion mutant lacking the EP153R gene, we have detected, in several virus-sensitive cells,

African swine fever virus (ASFV) A224L is a member of the inhibitor of apoptosis protein (IAP) family. We have investigated the antiapoptotic function of the viral IAP both in stably transfected cells and in ASFV-infected cells. A224L was able to substantially inhibit caspase activity and cell death

Rift Valley fever virus (RVFV) is a member of the genus Phlebovirus within the family Bunyaviridae. It can cause severe epidemics among ruminants and fever, myalgia, a hemorrhagic syndrome, and/or encephalitis in humans. The RVFV M segment encodes the NSm and 78-kDa proteins and two major envelope

Cell death is a common and reproducible feature of the development of many mammalian tissues/organs. Two well-known examples of programmed cell death (PCD) are the cell deaths associated with fusion of the neural folds and removal of interdigital mesenchymal cells during digit formation. Like normal

L-selectin mediates lymphocyte extravasation into lymphoid tissues through binding to sialomucin-like receptors on the surface of high endothelial venules (HEV). This study examines the biochemical basis and regulation of interactions between L-selectin, an integral transmembrane protein, and the

A major problem in autologous stem cell transplantation is the occurrence of relapse by residual neoplastic cells from the graft. The selective toxicity of hyperthermia toward malignant hematopoietic progenitors compared with normal bone marrow cells has been utilized in purging protocols. The

BACKGROUND Using vital dyes, we have previously shown that while hyperthermia (HS), 4-hydroperoxycyclophosphamide (4CP), and staurosporine (ST) induce cell death within specific tissues (e.g., neuroepithelium) of day 9 mouse embryos, cells of the heart are resistant to the cell death-inducing

BACKGROUND Previous work has shown that teratogens such as hyperthermia (HS), 4-hydroperoxycyclophosphamide (4CP), and staurosporine (ST) induce cell death in day 9 mouse embryos by activating the mitochondrial apoptotic pathway. Key to the activation of this pathway is the activation of a caspase

Cell therapy for Duchenne muscular dystrophy and other muscle diseases is limited by a massive early cell death following injections. In this study, we explored the potential benefit of heme oxygenase-1 (HO-1) expression in the survival of porcine myogenic precursor cells (MPCs) transplanted in pig

Previously we showed that teratogen-induced cell death in mouse embryos is apoptotic in nature, i.e., involves the release of cytochrome c from mitochondria and the subsequent activation of caspase-3, cleavage of poly (ADP-ribose) polymerase (PARP), and internucleosomal DNA fragmentation. Herein we

We used quantitative multiparameter flow cytometric assays to simultaneously detect viable, apoptotic, and necrotic human peripheral blood mononuclear cells (PBMC) and immunophenotyped lymphocyte subsets within the PBMC. Apoptosis was induced by a spectrum of treatments, including camptothecin,
