Requirement of Thymus (t) Lymphocytes for Resistance to Listeriosis
نویسندگان
چکیده
Spleen cells of mice infected with Listeria monocytogenes were adoptively transferred to normal mice. Such lymphocytes conferred resistance to a lethal challenge with Listeria. Hyperimmunization of the donor reduces the number of cells necessary to transfer effective immunity. Such spleen cells if treated with anti-theta serum do not transfer resistance to Listeria. Hence, thymus (T) lymphocytes are involved in the resistance to infection with the facultative intracellular bacteria L. monocytogenes.

Impaired Production of Mediator T Cells as a Basis for the Decreased Resistance of Senescent Mice to Listeriosis* BY PARSOTTAM J. PATEL
There is evidence that aging of mammals is accompanied by a profound decrease in an individual's capacity to resist infections caused by microbial pathogens (1-6). It is generally inferred that decreased resistance in aged mammals is a reflection of their waning immunocompetence. This notion derives support from the findings that are primarily concerned with age-related changes in the antibody ...
متن کاملP124: Listeriosis in Central Nervous System
Listeriosis is one of the CNS inflammatory diseases which is happened majority in the form of sporadic. Listeriosis is ingested with the food. Infection occurrence in an exposed person depends on the number of organisms ingested, the virulence of the organisms strain and the individual condition. It is known that Listeriosis has decisive importance as an infection which the cellular immunodefen...
متن کاملRelationship of antimicrobial cellular immunity to delayed hypersensitivity in Listeriosis.
The relationship of antimicrobial cellular immunity to delayed hypersensitivity (DH) was studied in mice antigenically stimulated by living Listeria monocytogenes confined to diffusion chambers in peritoneal cavities or by subcutaneous inoculation of sublethal doses of the organism. Mice showed DH reactions when tested 6 days after inoculation, and reactions were positive for at least 90 days i...
متن کاملRole of T-lymphocytes in production of antibody to antigens of Rickettsia tsutsugamushi and other Rickettsia species.
The requirement of thymus-dependent lymphocytes for antibody production to Rickettsia tsutsugamushi, Rickettsia akari, Rickettsia conorii, and Rickettsia typhi was investigated by comparing antibody production in athymic (nu/nu) or thymus-bearing BALB/c mice. Athymic BALB/c mice produced antibody after infection with R. akari, R. conorii, and R. typhi as measured by indirect fluorescent antibod...
متن کاملControl of natural killer cell-mediated innate resistance against the intracellular pathogen Listeria monocytogenes by gamma/delta T lymphocytes.
Listeria monocytogenes is an intracellular bacterium which causes an acute infectious disease in mice. Initial host resistance depends on innate immunity mediated primarily by natural killer (NK) cells followed by specific alpha/beta T cells, which are central to acquired specific immunity. Gamma/delta T lymphocytes seem to provide a link between the innate and the specific immune response. All...
