چکیده

We have tested the hypothesis that entenc bacteria are necessary for formation of intestinal adenomas in C57BU6-Apc@'@I+mouse. Germ-free mice developed 2-fold fewer adenomas than conventional controls in the medial small intestine (7.3 versus 14.9; P < 0.003), but there were no significant differences in the rest of the intestinal tract. We conclude that microbial status does not strongly alter the adenoma phenotype in this mouse model of familial adenomatous polyposis. In parallel, we have found that CS7BL/6-ApcMt―/+ mice mutated at the beige locus, which controls natural killer activity, are also unaltered in adenoma multiplicity.

Intestinal neoplasia in the ApcMin mouse: independence from the microbial and natural killer (beige locus) status.

We have tested the hypothesis that enteric bacteria are necessary for formation of intestinal adenomas in C57BL/6-ApcMin/+ mouse. Germ-free mice developed 2-fold fewer adenomas than conventional controls in the medial small intestine (7.3 versus 14.9; P < 0.003), but there were no significant differences in the rest of the intestinal tract. We conclude that microbial status does not strongly al...

Positional Relationship between Natural Killer Cells and Distribution of Sympathetic Nerves in Decidualized Mouse Uterus

Background: Uterine natural killer (uNK) cells are the most abundant leukocytes in pre-implantation endometrium and early pregnancy deciduas in humans and rodents. They are associated with structural changes in maternal spiral arteries but regulation of their re-cruitment and activation is incompletely understood. The major subpopulation of uNK cells in humans expresses CD56, the neural cell ad...

Heterogeneity of natural killer cells in the mouse

Mice were treated with the bone-seeking isotope, 89Sr, cyclophosphamide, and short-term lethal irradiation in vivo, and murine spleen cells are treated with anti-Nk-1.2 plus complement (C) in vitro. Fresh spleen cell suspensions from the above groups and from beige and neonatal mice were subsequently tested for natural killer (NK) cell activity against a panel of lymphoid and nonlymphoid tumor ...

Natural killer cell activity and macrophage-dependent inhibition of growth or killing of Mycobacterium avium complex in a mouse model.

Natural killer (NK) cells from spleens of normal and Mycobacterium avium complex (MAC)-infected C57 black mice (C57 BL/6 bg/+) were examined for their capacity to activate splenic and peritoneal macrophages from beige mice to inhibit or kill intracellular MAC. Peritoneal and splenic macrophages from beige mice were exposed in vitro to NK cells obtained from MAC-infected and uninfected black mic...

Relationship between rejection of several syngeneic tumors and retrovirus production by 5-bromodeoxyuridine-grown melanoma cells: lack of protection in natural killer-deficient beige mice.

Bromodeoxyuridine-grown B16 melanoma cells (C3471) immunize mice against not only the parent melanoma but also two other C57BL/6 tumors: a mammary adenocarcinoma and a methylcholanthrene-induced sarcoma. We have shown that the endogenous retrovirus induced in C3471 cells by bromodeoxyuridine can persistently infect feral mouse (SC1) cells and that they then become as efficient as C3471 cells in...
