    Opis:
    Objective: To determine transforming growth factor (TGF) β1, interleukin (IL) 4, and IL-10 concentrations in human milk and to assess the relationship between allergic disorders in mothers and the content of the interleukins in their milk. Material and methods: Thirty allergic and 46 healthy mothers were included in the study. Colostrum was collected 2-3 days after delivery. Cytokine concentrations were determined with commercial enzyme-linked immunosorbent systems. Results: TGF-β1was found in milk from 23 women in the control group (53.49%) and 11 in the allergy group (37.93%). When TGF-β1 was present, the median concentration was higher in the allergy group than in the control (61.5 and 30.4 pg/mL, respectively; P < 0.004). IL-10 was present in the colostrum of all the women and the median IL-10 concentration did not differ between the allergy (50.5 pg/mL) and control (51.5 pg/mL) groups. The probability of occurrence of a positive IL-4 value in the allergy group was greater than in the control group (chi-squared [df=1] = 2.60, P < 0.053). Median IL-4 level did not differ significantly between the two groups (0.5 and 0.5 pg/mL respectively). Conclusions: TGF-β1 was detected less often in the colostrum of allergic mothers than in that of mothers without allergy (but the difference was not statistically significant). IL-4 was found more often in the colostrum of allergic mothers than nonallergic ones. The allergy status did not correlate with IL-10 concentration.

    Opis:
    Growth arrest and DNA damage-inducible (GADD) 45 proteins are regulators of cell death and survival. The proinflammatory cytokine IL-1β strongly increases the level of the transcript encoding GADD45α in rat insulin-producing INS-1E cells. The activation of Gadd45α gene is clearly dependent on JNK and NF-κB activation and the synthesis of the secondary mediator nitric oxide (NO). Interestingly, the observed twelve-fold increase in the GADD45α-coding transcript level is not followed by increased expression of GADD45α at the protein level. An analysis of IL-1β toxicity in INS-1E cells overexpressing GADD45α revealed no correlation between the GADD45α protein level and the sensitivity to IL-1β toxicity. These findings suggest that the potential engagement of GADD45α in IL-1β toxicity towards beta cells is limited to the effects induced by the basal expression level of this protein.

    Opis:
    This work was carried out to investigate the role of Glutathione S-Transferase M1 (GSTM1) null genotype frequency in prognosis of β-thalassemia, and to detect the correlation between GSTM1 null genotype and appearance of cardiac complications in β-thalassemia. Materials and Methods. The studied groups in the present work were divided to three groups (group I: 20 healthy subjects, group II: 56 β-thalassemic patients and group III: 16 β-thalassemic patients with cardiac complications were taken from group II). The measurement of human high sensitive C-reactive protein (hs-CRP) was performed using nephelometry. GSTM1 genotype was detected by Polymerase Chain Reaction (PCR) and cardiac complications were determined by using Echocardiography. Results. A statistically significant increase in hs-CRP and interleukin-6 (IL-6) levels was found in β-thalassemic patients with cardiac complications compared to normal subjects. Results showed no relation between GSTM1 null genotype frequency neither with β-thalassemia nor with cardiac complications appearance, where the interaction between GSTM1 null genotype in β-thalassemic patients with cardiac complications and healthy subjects were insignificant compared to subjects with GSTM1 non-null genotype. Conclusions. GSTM1 null genotype frequency has no role in β-thalassemia or cardiac complications appearance.

    juvenile idiopathic arthritis
    Opis:
    Background: Juvenile idiopathic arthritis (JIA) is a chronic, heterogenous inflammatory disease of unclear pathogenesis. JIA is hypothesized to be linked to a defective immune regulation. Anti-inflammatory cytokines belong to the best known regulatory factors. T-regulatory cells are a crucial cellular component of immune tolerance. One of their functions is synthesis of interleukin 10 (IL-10) and transforming growth factor beta1 (TGF-β1). The aim of this study was to determine the proportion of T-regulatory cells (CD4+CD25highFOXP3+) in peripheral blood, and serum levels of TGF-β1 and IL-10 in patients with JIA. Methods: The study included 25 patients with newly diagnosed JIA: oligoarthritis (n=17) and polyarthritis (n=8). The control group was comprised of 17 healthy children. CD4+CD25highFOXP3+ T cells in peripheral blood were quantified by means of three-color flow cytometry. Serum concentrations of TGF-β1 and IL-10 were estimated with ELISA. Results: The proportion of peripheral CD4+CD25highFOXP3+ cells in patients with JIA was significantly higher than in the controls (p=0.04). The two groups did not differ significantly in terms of their TGF-β1 and IL-10 concentrations. Conclusions: At the time of diagnosis, children with JIA presented with an elevated proportion of T-regulatory cells (CD4+CD25highFOXP3+) in peripheral blood. Anti-inflammatory cytokines, IL-10 and TGF-β1, are not upregulated in the serum of patients with JIA, and therefore should not be considered as biomarkers of this condition.

    Opis:
    Interleukin 1 (IL-1) and interleukin 6 (IL-6) are typical examples of multfunctonal pro-infammatory cytokines involved in the regulaton of the immune response, hematopoiesis, and infammaton. Both peripheral and intraventricular administraton of these cytokines causes acute phase symptoms, e.g. fever, actvaton of the hypothalamic-pituitary-adrenal axis and psychological depression. The amygdala belongs to the structures of the limbic system involved in the regulaton of the immune response. Increased actvity of immune system may lead to changes in the role of amygdala, medial prefrontal cortex, anterior cingulate cortex or insula. The aim of the study was to present the mutual interactons between the amygdala and pro-infammatory cytokines such as interleukin-1β (IL-1 beta) and interleukin 6 (IL-6). Most of the data included in this review comes from animal studies.
