Pro Inflammatory Cytokines

Inflammatory mediators have an important role in the pathogenesis of periodontal disease. One of the leading mediators of the initiation of the pathological process is interleukin-1 (IL-1) – an endogenous pyrogen, a lymphocyte-activating factor. Numerous pro-inflammatory effects of interleukin-1β (IL-1β) occur in synergy with tumor necrosis factor alpha (TNF-α) and interleukin-6 (IL-6), effects on hematopoiesis, participates in nonspecific anti-infective defense.The objective of the study is to determine levels of interleukin-6 and tumor necrosis factor alpha (TNF-α) in patients with hypertension II stage and generalized periodontitis of the II degree depending on the treatment method.There were examined 30 patients with hypertension of the II stage and with generalized periodontitis of the II degree. Patients’ age ranged from 35 to 54 years. These patients were divided into two groups. The control group included 10 patients without general somatic pathology and with healthy periodontitis of the same age. The result of the analysis of tumor necrosis factor alpha (TNF-α) in patients in the first group before the treatment was 10.69±2.33 pg/ml. After the treatment this indicator was 6.97±1.57 pg/ml (p>0.1) in patients of the first group.In patients of the second group the tumor necrosis factor alpha (TNF-α) was 9.49±2.2 pg/ml; after the treatment according to the offered scheme this figure decreased up to 2.77±0.9 pg/ml (p<0.01). The level of tumor necrosis factor alpha (TNF-α) in the control group was 1.5±0.77 pg/ml.Interleukin-6 was 9.91±2.04 pg/ml before the treatment in the first group. After the treatment according to the standard scheme, the level of interleukin-6 was 6.33±0.97 pg/ml (p>0.1). In the second group, before the treatment the level of  interleukin-6 was 9.65±2.41 pg/ml; after the treatment according to the offered scheme it was 2.62±0.5 pg/ml (p<0.01). In the control group the interleukin-6 level was 2.24±0.51 pg/ml.Analyzing the obtained results after the treatment in both groups we can conclude: after the treatment of generalized periodontitis of the II degree in patients with hypertension of the II stage, indices of pro-inflammatory cytokines decreased and ranged in normal limits; in patients from the second group (who received the offered scheme of treatment -including medicines) indexes of pro-inflammatory cytokines were significantly lower than in patients with the standard treatment scheme; the proposed scheme of treatment is more effective for treatment patients with generalized periodontitis of the II degree and hypertension of the II stage.

BACKGROUND: Macrophages have been widely used for in vitro studies. Despite different types and doses of stimulatory agents that have been tested, there is no consensus for the method. AIM: This study was aimed to determine a sufficient dose of lipopolysaccharide (LPS) to stimulate inflammatory response in macrophages. METHODS: Whole blood was collected from four donors after written informed consent. The monocytes were isolated from peripheral blood mononuclear cells and stimulated with macrophage colony-stimulating factor, LPS, and Interferon-gamma for 6 days until differentiated into macrophages. The production of Tumor necrosis factor-alpha (TNF-α) and Interleukin-6 (IL-6) were quantified after 24-h further stimulation with 100 ng/mL and 2 μg/mL of LPS. RESULTS: Both doses increased TNF-α _production compare to their controls, but not statistically different (p > 0.05). There were also no differences in IL-6 production between treatments, 56.55 ± 32.30 pg/mL and 70.96 ± 65.08 pg/mL, respectively. CONCLUSION: A dose of 100 ng/mL of LPS was sufficient to stimulate inflammatory response in human monocyte-derived macrophages. A 24-h duration of macrophage stimulation was sufficient to observed the production TNF-α.

ABSTRACT During a Streptococcus pyogenes infection in interleukin-6 (IL-6)-deficient mice, there is elevation of serum tumor necrosis factor alpha (TNF-α) levels, muscular necrosis, and death compared with infection of C57BL/6 mice. Anti-TNF-α monoclonal antibody treatment decreased mortality and muscular necrosis in the infected IL-6-deficient mice. These results suggest that IL-6 plays a crucial protective role via suppression of TNF-α production in S. pyogenes infection.

Abstract The aim of this study was to determine the effects of L-carnitine and magnesium on the levels of tissue malondialdehyde, 8-hydroxy-2’-deoxyguanosine, and cytokines (tumor necrosis factor alpha, interleukin-6) in streptozotocin-induced experimental diabetes in rats. Eighty male Wistar albino rats (200-250 g) were divided into 8 groups with 10 rats in each group. The groups received the following treatments: Control group; 2 ml distilled water (by gavage); Group 2: 50 mg/kg (b.w.) i.p. streptozotocin; Group 3: 125 mg/kg (b.w.) magnesium; Group 4: 300 mg/kg (b.w.) L-carnitine; Group 5: 125 mg/kg (b.w.) magnesium +300 mg/kg (b.w.) L-carnitine; Group 6: 50 mg/kg (b.w.) streptozotocin +125 mg/kg (b.w.) magnesium; Group 7: 50 mg/kg (b.w.) streptozotocin +300 mg/kg (b.w.) L-carnitine and Group 8: 50 mg/kg (b.w.) streptozotocin +125 mg/ kg (b.w.) magnesium+300 mg/kg (b.w.) L-carnitine administered for 4 weeks. Liver and kidney malondialdehyde, 8-hydroxy-2’-deoxyguanosine, tumor necrosis factor alpha and interleukin-6 levels did not change in the magnesium, L-carnitine, and magnesium + L-carnitine groups compared to the control. The highest levels of malondialdehyde, 8-hydroxy-2’-deoxyguanosine, tumor necrosis factor alpha and interleukin-6 were determined only in the group with diabetes (Group 2). Lipid peroxidation, DNA damage, and cytokine levels were significantly reduced in diabetic animals with the administration of magnesium and L-carnitine separately or in combination. Based on the obtained results it can be concluded that magnesium and L-carnitine may have antidiabetic effects, especially in combination.

Mason, M., Cuadra, E. J., Elsasser, T. H., Lopez, J. and Yoonsung, J. 2013. Evaluating the interaction between progesterone, tumor necrosis factor-alpha and cortisol on early loss of transferred embryo in beef cows. Can. J. Anim. Sci. 93: 217–225. Fifty-eight non-lactating cows previously synchronized for estrus were assigned to two treatments to assess the effects of progesterone supplementation and its correlation with tumor necrosis factor-α (TNF-α) and cortisol on the survival of the transferred embryos. On day 7 after exhibiting estrus (day 0), cows in both groups received embryos. In contrast with the control group, animals in the CIDR-group had a controlled internal drug release (CIDR) additionally inserted. Blood samples for progesterone, TNF-α and cortisol analysis were taken immediately before insertion and removal of CIDRs and 7 d after insertion. Progesterone did not differ between the control and the CIDR animals at any day of the study; however, it significantly increased at 7 and 14 d after insertion of the embryos in the control animals, compared with the levels observed in that same experimental group at the time of the transfer. Regardless of the treatment, all pregnant cows experienced a significant increase in progesterone from day 0 to day 7. Progesterone on day 0 was correlated to itself (r=0.46) on day 14 and to TNF-α (r=−0.37) on day 0 in pregnant animals; TNF-α on day 7 was significantly higher in pregnant cows compared with non-pregnant and correlated between day 0 and day 14. These results suggest that high levels of progesterone during the first 14 d after the transfer are indicative of the survival of transferred embryos. Additionally, these data also indicate that the decrease in TNF-α concentration on day 7 after the transfer of embryos may be associated with the low concentrations of progesterone observed in the non-pregnant animals.
