background: the aim of this study was to investigate the effects of leishmania major infection on the induction of oxidative stress in skin and lung of female mice. methods: balb/c mice were randomly divided into the control and experi-mental groups. the experimental groups were subcutaneously infected with in-oculums promastigotes of l. major . the animals were sacrificed at 20, 40, 60, 90 and...

background: leishmaniasis is a worldwide disease prevalent in tropical and sub tropical coun­tries. many attempts have been made and different strategies have been approached to develop a potent vaccine against leishmania . dna immunisation is a method, which is shown to be effec­tive in leishmania vaccination. leishmania soluble antigen (sla) has also recently been used leishmania vaccination....

Susceptibility of BALB/c mice to Leishmania major depends on the early production of IL-4 by CD4(+) T cells which react to the parasite LACK antigen. Here, we show that LACK-specific cells are rapidly recruited to the site of infection and favor the early dissemination of L. major to the internal organs.

A sensitive biological assay has been developed for studying the frequency of virus induction from mouse cells containing poorly infectious endogenous C-type viruses. A low spontaneous frequency of virus activation of one but not a second endogenous virus of BALB/c cells has been demonstrated. The resistance of BALB/c cells to superinfection by the more inducible virus appears to be absolute, w...

Evaluation of Anticancer Effect Ginger (Zingiber officinale) and Garlic (Allium sativum) Extracts on Breast Cancer in BALB/c Mice

Successful intrauterine hematopoietic cell transplantation (IUT) for congenital hemoglobinopathies is hampered by maternal alloresponsiveness. We investigate these interactions in semi-allogenic murine IUT. E14 fetuses (B6 females × BALB/c males) were each treated with 5E+6 (B6) or paternal (BALB/c) bone marrow cells and serially monitored chimerism (>1% engraftment), trafficked immune cells, r...

In contrast to intact BALB/c mice, BALB/c mice rendered deficient in Vbeta4+ CD4+ T cells develop a Th1 response to infection with Leishmania major and are resistant. Vbeta4-deficient BALB/c mice are unable to generate the early IL-4 transcription occurring in Vbeta4 Valpha8 CD4+ T cells of BALB/c mice within 1 day of infection. Here we demonstrate that treatment of Vbeta4-deficient BALB/c mice...

Spleen cells from BALB/c and C57BL/6 mice were tested for their reactivity against reciprocal hybrid tissues ((BALB/c x C57BL/6) F(1) and (C57BL/6 x BALB/c) F(1)) in three assay systems: the mixed lymphocyte reaction (MLR); the Simonsen spleen-weight graft-vs.-host (GVH) assay; and a GVH mortality assay. It was shown that both F(1)'s serve as equally effective stimulators of parental cells in t...
