AB  - Our previous research showed a higher reactivity of DA (compared to AO rats) to antigens that cause skin and lung inflammatory reactions. In order to examine the effect of strains on the immune responses of other regions, the effect of oral (in drinking water, 30 days) intake of cadmium, a known food and water contaminant, on the intestinal immune response of AO and DA rats was analyzed. Despite similar amounts of cadmium deposited in the intestines of both strains, the reduction in Lactobacillus (important for maintaining immune homeostasis in the intestine) and tissue damage (histologically and according to the marker of tissue necrosis, HMGB-1) was more pronounced in DA rats.Changes, including the activity of antioxidant defense enzymes (superoxide dismutase and catalase), increased concentrations of IFN-γ and IL-17, and no changes in IL-10, which were detected in intestinal homogenates only in DA strains, indicate a more intense intestinal inflammatory reaction. compared to AO strain. The same concentrations of cadmium detected in the main draining (mesenteric) lymph nodes (MLC) led to the induction of mRNA for metal-binding redox proteins (metallothioneins, MT) only in DA rats. The presence of a proinflammatory cytokine response (protein products and mRNA) of MLC cells, detected predominantly in DA strains, indicates a more pronounced induction of cells that produce these cytokines.Increased cell proliferation and oxidative activity of MLC cells, as well as the number of CD68 +, NKG2D + and CD11b + cells only in DA rats, with a differential change in IL-10 (decrease in DA, increase in AO) emphasizes the inflammatory character of MLC rat microenvironment of this strain. The absence of similar changes in the spleen (at the same tissue load of cadmium as MLC) indicates the influence of damaged intestinal tissue on the activity of regional lymph nodes, and the more intense response of MLC DA soy reflects greater efforts to prevent systemic immune response to changes in intestinal homeostasis.

AB  - The impact of genetic background on effects of acute i.p. cadmium administration (0.5 mg/kg and 1 mg/kg) on basic immune activity of spleen and lungs was examined in two rat strains, Albino Oxford (AO) and Dark Agouti (DA), known to react differently to chemicals. More pronounced inhibition of Concanavalin A (ConA)-induced and Interleukin (IL)-2 stimulated spleen cell proliferation as well as higher levels of nitric oxide (known to decrease cell's proliferative ability) in DA rats at 1 mg/kg, along with greater inhibition of ConA-induced Interferon (IFN-γ)-production by total and mononuclear (MNC) spleen cells and IL-17 production by spleen MNC in DA vs. AO rats at this dose show greater susceptibility of this strain to Cd effects on spleen cells response. More pronounced infiltration of neutrophils/CD11b+ cells to lungs of DA rats treated with 1 mg/kg of Cd and decreased IL-17 lung cell responses noted solely in DA rats speaks in favor of their higher susceptibility to this metal. However, lack of strain disparity in lung cells IFN-γ responses show that there are regional differences as well. Novel data from this study depict complexity of the influence of genetic background on the effects of cadmium on host immune reactivity.

AB  - Influence of genetic background on toxicity of oral cadmium (Cd) administration (30 days, in drinking
water; 5 ppm and 50 ppm of cadmium) was examined in Albino Oxford (AO) and Dark Agouti (DA) rats.
Similar cadmium deposition was noted in gut and draining mesenteric lymph nodes (MLN) of both
strains but intensity and/or the pattern of responses to cadmium in these tissues differ. Less intense
intestinal damage and leukocyte infiltration was observed in gut of cadmium-exposed AO rats. While
gut-associated lymph node cells of DA rats responded to cadmium with an increase of cell proliferation,
oxidative activity, IFN-g, IL-17 production and expression, no changes of these activities of MLN cells of
cadmium-treated AO rats were observed. Spleen, which accumulated cadmium comparable to MLN,
responded to metal by drop in cell viability and by reduced responsiveness of proliferation and cytokine
production to stimulation in DA rats solely, which suggest tissue dependence of cadmium effects. More
pronounced cadmium effects on MLN and spleen cells of DA rats (which accumulated similar cadmium
doses as AO rats), showed greater susceptibility of this strain to cadmium. The results presented, for the
first time, depict the influence of genetic background to effects of oral cadmium administration.

AB  - Introduction: Toxic metal cadmium (Cd) is important food and drinking water contaminant. The majority of ingested cadmium retained in the gastrointestinal tract (GIT) mucosa
which allocates GIT as its main target. Mechanisms of induction of intestinal inflammatory response are largely unknown.
Materials and Methods: Effect of subchronic (30 days) oral (in water) cadmium administration (5 ppm and 50 ppm) was examined in Dark Agouti (DA) and Albino Oxford (AO) rats.
Beside intestinal immune response, activity of draining mesenteric lymph node (MLN) cells, central place for induction of intestinal immune tolerance and local protective responses,
was evaluated.
Results: In both rat strains cadmium consumption resulted in reduction of bacteria (Lactobacillus strain), intestinal tissue damage, modulated antioxidant enzymes activity and
inflammation [increased proinflammatory cytokine (TNF, IL-1β, IFN-γ, IL-17) content in DA rats; increased TNF and IL-10 content in AO rats] in duodenal homogenates. Accumulation
of cadmium in MLN was followed by stress response [elevation of MLN glutathione and metallothionein mRNA levels] only in DA rats. Stimulation of both adaptive (proliferation, Th1
and Th17 cytokine response) and innate immune activities (NKG2D+, CD68+ cells, selected oxidative activities, IL-1β) in MLN was observed, more pronounced in DA compared to AO
rats.
Conclusions: Oral intake of cadmium resulted in intestinal damage, inflammation, and induction of proinflammatory milleu and innate effector cell activities in MLN. Cadmiuminduced proinflammatory responses in DA rats but discrete immune responses of AO rats imply strain-dependent effects of oral cadmium administration.

AB  - Conflicting data exist concerning cadmium
effects on immune system depending on the
experimental model, exposure or tissue/activity
examined. In this study immunotoxicity of acute
intraperitoneal and oral cadmium
administration was investigated in rats. The
use of the inflammation-prone inbred Dark
Agouti (DA) and less reactive Albino Oxford
(AO) rats showed differential (immune activityrelated and/or strain-related) effects of
cadmium (1 mg of Cd/kg, i.p.) on spleen
immune responses. A decrease in ConAinduced proliferation (related to altered spleen
cells responsiveness to IL-2) and of IFN-γ
(independently of IL-4 and IL-10) was more
pronounced in DA rats. Increased innate
immunity splenocyte activity (granulocyte
CD11b+ cells, iNOS mRNA and NO
production, myeloperoxidase MPO activity, IL1β mRNA and IL-1β protein product levels)
were observed in both strains (some of them
more pronounced in DA rats), while a decrease
in respiratory burst (dihydrorhodamine/DHR
oxidation) was similar. 30-day oral intake of 5
ppm and 50 ppm of cadmium by DA rats
resulted in reduction of some probiotic bacteria,
villous damage and intestinal inflammation
[(increased levels of High Mobility Group
Box1/HMGB1, antioxidant enzyme (superoxide
dismutase/SOD and catalase/CAT) activity and
proinflammatory cytokine (TNF, IL-1β, IFN-γ,
IL-17) in gut homogenates]. Stimulation of both
adaptive (increased cellularity, proliferation,
IFN-γ and IL-17cytokine responses) as well as
innate immune activity (increases in numbers
of NK cells and M1-like macrophages,
oxidative cell activities, IL-1β) of gut draining
(mesenteric) lymph nodes was associated with
decreased or unchanged antiinflammatory
cytokine (IL-10) cell response. Differential
(immunosuppressive and immunostimulatory)
effects noted in the same tissue (spleen)
should be taken into account when exploring
immunotoxicity of this metal. Stimulation of gut
immune responses imply dietary cadmium as
health risk factor.
