The antiherpesvirus activity and cytotoxicity of sangivamycin

Current Eye Research, 1987
Sangivamycin, 4-amino-5-carboxamido-7-(beta-D-ribofuranosyl)-pyrrolo[2,3-d]-pyrimidine is a structural analog of adenosine belonging to a group of nucleosides classified as pyrrolopyrimidines. Sangivamycin, an adenosine deaminase resistant analog, was found to inhibit the replication of three strains of herpes simplex virus type 1 (HSV-1) by 50% (ED50)

Cytotoxic Activity Methods

2023
Natural products have formed the basis of traditional medicine systems throughout human history. Today, drug discovery studies from natural origins continue rapidly and efficiently with modern methods. Among the many activities, cytotoxic activity is related to the behaviour of test material on cell viability and cellular growth.

Cytotoxic activities of fish leucocytes

Fish & Shellfish Immunology, 2006
Like mammalian leucocytes, white blood cells of fish are able to kill altered (e.g. virus-infected) and foreign (allogeneic or xenogeneic) cells. The existence of natural killer (NK)-like and specific cytotoxic cells in fish was first shown using allogeneic and xenogeneic effector/target cell systems.

Targeting and Activation of Cytotoxic Lymphocytes

2015
Des anticorps heteroconjugues ont permis d'etudier et de moduler la specificite des cellules cytotoxiques in vivo et in vitro. Il faut determiner quel anticorps bispecifique sera capable in vivo de «cibler» certaines cellules cytotoxiques qui pourront avoir des applications ...

Cytotoxic activity of Staphylococcus hyicus

Veterinary Microbiology, 1991
Culture supernatants from a number of Staphylococcus hyicus strains caused toxic effects to both murine fibroblast and porcine keratinocyte cells in culture. The extent of cytotoxicity was shown to differ between strains and may provide an indication of strain virulence. Purification of cytotoxic activity produced by S.

Specific tumoricidal activity of cytotoxic macrophages and cytotoxic lymphocytes

Cancer Immunology, Immunotherapy, 1986
The antitumor potency and specificity of syngeneic immune peritoneal exudate cells were tested. Groups of DBA/2 mice were immunized against syngeneic SL2 tumor cells. Then 6 days after the last immunization the antitumor potency, and the specificity of the immunization reaction was tested by injecting groups of the immunized mice with 10(3) to 5 X 10(7)

Cytotoxic Activity of Lymphocytes

The Journal of Immunology, 1978
Abstract To detect the cellular origins of α-lymphotoxin (α-LT), we cultured various subpopulations of human blood lymphocytes separated by erythrocyte-rosetting techniques with various mitogens. T cell-enriched subpopulations responded to PHA by increased 3H-thymidine uptake into DNA and large amounts of α-LT production.

Cytotoxic Activity of Lymphocytes

The Journal of Immunology, 1972
Abstract Antibody to human lymphotoxin was elicited in rabbits immunized with partially purified supernatants of human spleen cells stimulated by phytohemagglutinin; Anti-LT activity, assayed by neutralizing soluble LT toxicity to indicator mouse L cells, is confined to the immunoglobulin fraction of the serum; it cannot be removed by ...
