Vesicular stomatitis virus (VSV) elicited cytotoxic thymus-derived lymphocytes (CTLs) in mice of the BALB/c and three congenic strains (BALB.b, BALB.k, BALB.HTG). CTL lysis of VSV-infected fibroblasts from the four strains was restricted by the target cells' major histocompatibility complex (H-2). Target cells were also infected with two(More)
Synthetic phospholipid vesicles (liposomes) containing the purified glycoprotein (G) of vesicular stomatitis virus (VSV) and solubilized membrane proteins from cells of the appropriate H-2 haplotype elicited H-2-restricted cytotoxic T lymphocytes (CTL) that lysed VSV-infected target cells. The CTL were elicited by intact liposomes, not by released(More)
The acyl group composition of the phospholipids from normal chick embryo fibroblasts and from cells transformed by Rous sarcoma virus was determined by gas-liquid chromatography. Rous-transformed cells had less arachidonate (20:4) and more oleate (18:1) in membrane lipids than normal, growing cells. Normal density-inhibited cells had the lowest ratio of(More)
With the use of monospecific rabbit anti-G protein and mouse monoclonal anti-H-2Kk, we have analyzed the spatial relationship of the serologically defined H-2Kk antigens and the major surface glycoprotein (G protein) of vesicular stomatitis virus (VSV) to those antigens recognized by B10.A (k, d) anti-VSV cytotoxic T lymphocytes (CTLs). The ability of(More)
Vesicular stomatitis virus (VSV) infection of beige (bg/bg) mice induced levels of natural killer cytolytic activity comparable to that of uninfected normal bg/+ controls, but considerably less than natural killer activity in VSV-infected bg/+ mice. In contrast, VSV-infected bg/bg and bg/+ mice had essentially equivalent amounts of anti-VSV cytotoxic(More)
We have investigated the minimal molecular requirements for elicitation of anti-Sendai virus cytotoxic T lymphocytes (CTL), and the minimal molecular requirements for the recognition and lysis processes associated with anti-Sendai virus CTL-target cell interactions. This report demonstrates a) that the hemagglutinin-neuraminidase and/or fusion glycoproteins(More)
During each transplantation passage of a line of mouse myeloma tumor MOPC-315 through syngeneic (BALB/c) hosts, the tumor cells lose reactivity with cytotoxic thymus-derived lymphocytes directed against products of the BALB/c major histocompatibility complex (H-2d) and regain reactivity on transfer to fresh hosts. In contrast to this cyclical change, the(More)
A newly developed experimental model system was used to determine in vitro transformation-specific parameters which correlate with tumorigenicity. The data suggested that clonal herpes simplex virus type 2-transformed syngeneic rat embryo cells with intermediate, transformed rat embryo fibroblasts (t-REF-G-1) or high, rat fibrosarcoma tumorigenic potential(More)
