The water soluble ruthenium-p-cymene complexes Ru(eta(6)-p-cymene)X-2 (X = Cl, Br, I or NCS), [Ru(eta(6)-p-cymene)X-2(pta)] (X=Cl, Br, I, or NCS; pta=1,3,5-triaza-7-phosphatricyclo[3.3.1.1]decane) and the tetraruthenium cluster [H4Ru4(eta(6)-p-benzene ...
Double-stranded RNA-dependent protein kinase (PKR) has been implicated in interferon (IFN) induction, antiviral response and tumor suppression. We have generated mice devoid of functional PKR (Pkr%). Although the mice are physically normal and the inductio ...
TRIM5alpha is a restriction factor that limits infection of human cells by so-called N- but not B- or NB-tropic strains of murine leukemia virus (MLV). Here, we performed a mutation-based functional analysis of TRIM5alpha-mediated MLV restriction. Our resu ...
Viral replication usually requires that innate intracellular lines of defence be overcome, a task usually accomplished by specialized viral gene products. The virion infectivity factor (Vif) protein of human immunodeficiency virus (HIV) is required during ...
The human and simian immunodeficiency viruses (HIV and SIV, respectively) are members of the lentiviridae subgroup of retroviruses that cause a progressive failure of the host immunological functions culminating in the clinical collapse known as AIDS, or a ...
A framework for the construction of stable spectral methods on arbitrary domains with unstructured grids is presented. Although most of the developments are of a general nature, an emphasis is placed on schemes for the solution of partial differential equa ...
The CD28 costimulatory pathway is critical to T cell activation. Blockade of the interaction of CD28 with its ligands CD80 and CD86 using CTLA4-Ig has been proposed as a therapy for a number of immune-based disorders. We have used a murine model of influen ...
The lymphokine IFN-gamma is a pleiotropic immunomodulator and possesses intrinsic antiviral activity. We studied its significance in the development of antiviral immune responses by using IFN-gamma receptor-deficient (IFN-gamma R-/-) mice. After inoculatio ...
Papillomaviruses are believed to play an important role in the development of genital carcinoma. Herpes simplex virus (HSV) has been proposed as a cofactor. Here we show that HSV-1 interferes with the expression of human papillomavirus (HPV-18) genes in He ...
The genomes of human viruses herpes simplex 1 (HSV1) and varicella zoster (VZV), although similar in biology, largely concordant in gene order, and identical in many amino acid segments, differ widely in their genomic G + C (abbreviated S) content, which i ...
