A Cellular Basis of Immunity in Experimental Brucella Infection
Brucella suis, Brucella abortus, and Brucella melitensis were shown by microscopic and cultural procedures to multiply extensively within normal rat, mouse, and guinea pig monocytes maintained in vitro in cell cultures for 3 days. Intracellular growth of brucellae had no observable toxic effects on most monocytes, although many of the cells became completely engorged with brucellae within 3 day...
متن کاملCellular immunity after oral administration with V. cholerae.
The mechanisms of oral vaccination have not been clarified yet. In this study, the mechanisms that prevent infection by oral vaccination with Vivrio cholerae (V. cholerae) were investigated. Mice were orally vaccinated with the whole cells, or IF 30 of V. cholerae. The splenic cells or Peyer's patches (PP) cells of these mice were removed and their in vitro antibacterial activity against V. cho...

was later verified principally by others. One may note his theories of the relationship of viruses to cancer as an example: Viruses may cause cancer by making cells unresponsive to normal control mechanisms, or possibly, by transducing abnormal genes from one cell to another or, perhaps, the so-called cancer viruses may actually be abnormal genetic material derived from the first host. The pref...
متن کاملCellular basis of mechanotransduction.
Physical forces, such as those due to gravity, are fundamental regulators of tissue development. To influence morphogenesis, mechanical forces must alter growth and function. Yet little is known about how cells convert mechanical signals into a chemical response. This presentation attempts to place the potential molecular mediators of mechanotransduction within the context of the structural com...
متن کاملExtract and leaf powder effect of Artemisia annua on performance, cellular and humoral immunity in broilers
The effects of methanolic extract and leaf powder of Artemisia annua were studied on performance, cellular and humoral immunity in 240 Cobb broiler chicks in a completely randomized design. Control group did not receive any treatment. The chicks in the second and third groups were fed with feed which contained 2000 and 4000 ppm plant extract in diet and in the groups 4, 5 and 6 chicks received ...
