The cytokines IFN-γ, interleukin IL-1β, and TNF-α each up regulate the expression of major histocompatibility complex (MHC) and are therefore considered as inflammatory markers. The present study aimed to measure the serum levels of IFN-γ, interleukin IL-1β, and TNF-α in mice after induction of diabetes with streptozotocin and to correlate their levels to lipid and glycaemic profiles. The study included 40 Swiss Albino mice (20 males and 20 females), half of each male and female groups were made diabetic by intraperitoneal injection of streptozotocin. After 48 hours, the serum levels of INF-γ, IL1-β as well as TNF-α were measured with ELISA and their levels were correlated to lipid and glycaemic profiles. The levels of the cytokines, IFN-γ, IL1-β and TNF-α were measured and correlated to lipid profile, blood glucose and insulin. The serum levels of the three studied cytokines, IFN-γ, IL 1-β and TNF-α were statistically significantly higher among diabetic mice compared to the control group. Diabetic male mice (M-STZ mice) group showed significantly higher lipid profile compared to the control group (M-control). Cholesterol level was significantly higher among female control (F-control) compared to the M-control group. Cholesterol level was significantly higher among diabetic female mice (F-STZ mice) compared to the F-Control group. Regarding IFN-γ, IL 1-β and TNF-α levels, there were significant linear correlations with the glycemic profile (Glucose, insulin) reflected as positive correlation with blood glucose level and negative correlation with insulin level.

Type 1 diabetes is a chronic autoimmune disease of beta cells in the islets of Langerhans, which are responsible for making insulin. Even with insulin therapy, inflammatory complications will develop in the long term. The present study examines changes in serum levels of interleukin (IL)-6, IL-17, IL-10, tumor necrosis factor (TNF)-α, interferon (IFN)-γ, C-peptide, Insulin as well as fasting blood sugar (FBS) in control, diabetic and diabetic treated with curcumin groups. Thirty inbred C57BL /6 mice were randomly divided into three groups of 10 mice: group A consisted of healthy mice receiving citrate buffer, group B included a group of diabetic mice, and group C was a group of diabetic mice treated with curcumin. The cytokine levels were measured in the supernatant of stimulated splenocytes using enzyme -linked immunosorbent assay (ELISA). Radioimmunoassay was used to measure insulin and c-peptide levels. The FBS was measured by an automatic glucometer device. The levels of IL-6, IL-17, and IFN-γ, as well as FBS, was significantly decreased in the treated group with curcumin compared to the diabetic group mice (p<0.05). TNF-α levels were also low, but the difference was not significant. IL-10, plasma C-peptide, and insulin significantly increased in the supernatant of stimulated splenocytes of treated diabetic group than in the diabetic group (p<0/05). According to the results, this study supports the anti-diabetic and anti-inflammatory effects of curcumin; however, more studies are needed to investigate theeffects of curcumin and the dose-response relationship in this disease.

Multiple sclerosis (MS) is the most common neurological disease that happens at a young age. MS is an inflammatory disease; associated with the demyelination of the central nervous system. Therefore, some inflammatory factors are effective in the mechanism and progression of the disease. Melatonin, as a multi-effect substance including anti-inflammatory effects, can reduce symptoms of MS in patients with a change in their inflammatory factors level. In this study, 50 MS patients who were referred to the MS Society of Markazi Province were randomly selected. All patients were treated with routine MS treatment (interferon) and were divided into control (25 placebo recipients) and treatment (25 recipients of 3 mg melatonin per day for 24 weeks) groups. Anthropometric data of patients including height, weight, and age were determined. Blood samples were collected after fasting in order to determine serum levels of interleukin 1 beta (IL-1β) and tumor necrosis factor-alpha (TNF-α). Then, samples were immediately centrifuged for serum separation and sera were transferred to a freezer at -80°C and serum levels of these factors were determined; using ELISA kit. The results of this study showed that there was no significant difference between the control and treatment groups in terms of serum levels of TNF-α. However, the level of IL-1β was significantly reduced in the treatment group compared to the control group, indicating that melatonin decreases this inflammatory substance. Our findings suggest a valuable strategy in the treatment of patients who suffer from MS

Abstract Purpose Cyclophosphamide is an alkylating agent with nephrotoxicity that constraints its clinical application. Berberine is an isoquinoline derivative alkaloid with biological functions like antioxidant and anti-inflammatory. The current research intended to examine the nephroprotective impacts of berberine against cyclophosphamide-stimulated nephrotoxicity. Methods Forty animal subjects were randomly separated into five categories of control (Group I). Cyclophosphamide (200 mg/kg, i.p., on 7th day) (Group II), and groups III and IV that received berberine 50 and 100 mg/kg orally for seven days and a single injection of cyclophosphamide on 7th day. Group V as berberine (100 mg/kg, alone). On day 8, blood samples were drawn from the retro-orbital sinus to determine serum levels of blood urea nitrogen (BUN), creatinine (Cr), Neutrophil gelatinase-associated lipocalin (NGAL), and kidney injury molecule-1 (KIM-1) as biomarkers for kidney injury. Nitric oxide (NO), malondialdehyde (MDA) and glutathione (GSH) levels, catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx) activities as oxidative stress factors, tumor necrosis factor- α (TNF-α) and interleukin 1 beta (IL-1β) levels as inflammatory mediators were assessed in kidney tissue. Results The results of this study demonstrated that berberine was able to protect remarkably the kidney from CP-induced injury through decreasing the level of BUN, Cr, NGAL, KIM-1, NO, MDA TNF-α, IL-1β and increasing the level of GSH, CAT, SOD and GPx activities. Conclusion Berberine may be employed as a natural agent to prevent cyclophosphamide-induced nephrotoxicity through anti-oxidant and anti-inflammatory effects.

Abstract The exact mechanism of action of IVIg in the amelioration of immune thrombocytopenic purpura (ITP) is still unclear. Studies have suggested that IVIg may function through the regulation of cytokines, including interleukin-1 receptor antagonist (IL-1Ra), an inhibitor of phagocytosis. Using a mouse model relevant to ITP, we confirm an increase in mouse serum levels of IL-1Ra after exposure to IVIg, yet a recombinant IL-1Ra did not ameliorate thrombocytopenia. IVIg has also been shown to affect the expression of other regulatory cytokines. We have also recently established that IVIg specifically targets activating FcγRs on CD11c+ dendritic cells (DCs) as its primary mechanism of action in the amelioration of murine ITP. Herein, we show that IVIg functions therapeutically in mice lacking specific cytokines or their receptors that can potentially affect DC/macrophage function (IL-1 receptor, IL-4, IL-10, IL-12β, TNF-α, IFN-γ receptor, MIP-1α). This suggests that while IVIg may mediate the release of a variety of cytokines, the cytokines tested do not directly participate in the mechanism of IVIg action.

Although genetics plays an essential role in the pathogenesis of vitiligo, vitiligo pathogenesis is still unclear. Our aim was to investigate the role of IFN-γ expression and polymorphism in vitiligo susceptibility and whether intercellular adhesion molecule-1 (ICAM-1), tumor necrosis factor (TNF)-α, and TNF-β play a role in vitiligo pathogenesis as important inflammatory parameters. Eighty-five patients with vitiligo and 90 controls were investigated for IFN-γ gene expression by quantitative real-time PCR and genotyped for IFN-γ +874T/A (rs2430561) and IFN-γ +2109A/G (rs1861494) gene polymorphisms by sequence-specific primer (SSP)-PCR and PCR-restriction fragment length polymorphism (RFLP), respectively. Serum levels of inflammatory parameters were measured using ELISA. Frequencies of the +874 TT genotype and T allele were significantly higher in patients with active vitiligo than in stable patients (P = 0.01 and 0.03, respectively). Calculation of odds ratio suggested a 1.7-fold increased risk of vitiligo in individuals having the TA haplotype. We observed overexpression of IFN-γ mRNA with elevated serum levels of IFN-γ, ICAM-1, TNF-α, and TNF-β in patients with vitiligo when compared with the control group (P = 0.001, for all). In addition, these levels were elevated in patients with active vitiligo compared with stable patients with vitiligo (P = 0.008, 0.006, 0.01, 0.01, and 0.03, respectively), which suggests the involvement of these cytokines in disease activity. In conclusion, IFN-γ is a promising immunological marker in vitiligo pathogenesis.

Background: Curcumin demonstrated many pharmacological effects including antioxidants, anti-inflammation, eliminating free radicals, anti-tumor, lipid regulation, and anti-coagulation. Objective: This study aimed to assess and compare curcumin and nano-curcumin effects on lipid profile, oxidative stress, and inflammatory factors related to patients ‘heart. Method: This randomized, double-blind, placebo-controlled clinical trial was conducted on 90 patients undergoing coronary elective angioplasty which were randomly divided into 3 groups. The doses administered for 8 weeks were a 500 mg capsule of curcumin daily for the first group and an 80 mg capsule of nano-curcumin for the second group. However, the placebo group received capsules like curcumin. Lipid profile, oxidative stress factors, and inflammatory markers were measured at the baseline and end of the experiment. Results: Statistically significant changes were observed in the total cholesterol (TC), triacylglycerol (TG) and low-density lipoprotein cholesterol (LDL-C) in the intervention groups to the control group (p<0.05). Curcumin and nano-curcumin supplementation also improved significant changes in plasma levels of total antioxidant capacity (TAC), malondialdehyde (MDA), Superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), high-sensitivity C-reactive protein (hs-CRP), Interleukin 1 beta (IL-1β) and tumor necrosis factor-alpha (TNF-α) in comparison to the placebo (p<0.05). Furthermore, the nano-curcumin group compared to the curcumin group demonstrated significant changes (p<0.05) in TC, TG, SOD, MDA and TNF-α levels. Conclusion: The effects of curcumin on nano formula may be better for cardiac patients due to its high bioavailability.

Objective: Study the influence of doxycycline versus doxycycline with vitamin C drugs in the management of acne vulgaris on some immunological parameters which include ( IL-1β, IL-8, IFN-γ, TNF-α, and TLR2) and the following objectives were adapted: 1-Selection of population for the study ( control, patients) groups and follow up the patients after one month of treatment, the first group receive doxycycline and the second group receive doxycycline with vitamin C,2- Blood samples collection and separation of serums for immunological analysis, 3- Statistical analysis. Methods: This study is a randomized clinical trial carried out in clinical dermatology in Merjan Medical City in Babylon from September 2018 to March 2019. The number of subjects enrolled in the present study was 60; their age was between (14- 30 years), among whom 30 were acne patients, the remaining 30 subjects were apparently healthy individuals, and they were served as control. A dermatologist diagnosed a total of 30 acne patients to having moderate to severe acne and divided into two groups (15 patients in each group). Patients in the first group were treated with doxycycline (100mg) once daily after meal for 30 days, while in the second group patients were treated with doxycycline (100mg) capsule once daily after a meal in combination with vitamin C (500mg) chewable tablets once daily. After 1-month of therapy, the response was evaluated clinically and immunologically by measure the concentration of pro-inflammatory cytokines (IL-8, IL-1β, IFN-γ, TNF-α) and ( TLR-2 ) by using enzyme-linked immunosorbent assay (ELISA) and the results were compared to their levels before treatment and that in the control group. Results: Significant elevation in the serum levels ( p ≤ 0.001) of immunological parameter IL-8, IL-1β, IFN-γ, TNF-α, and TLR-2 among acne patients in comparison to the control. The clinical response in the first group was good, moderate and poor in 5 (33%), 7(47%) and 3(20%) respectively, while in the second group was good, moderate and poor in 7 (47%), 7(47%) and 1(6%) respectively, the immunological results showed that the serum levels to the (IL-1β, IL-8, IFN-γ, TNF-α) and (TLR-2 ) were more reduced in the second group compared to their levels in the first group. Conclusion: Significant elevation (p less than 0.001) in the serum levels of (IL-8, IL-1β, IFN-γ, TNF-α, and TLR-2) among moderate to severe acne patients in comparison to control group. Clinically the combination of doxycycline plus vitamin C was more efficient as therapeutically in comparison to doxycycline alone. Immunologically doxycycline plus vitamin C was more effective in reducing serum levels of (IL-8, IL-1β, IFN-γ, TNF-α, and TLR-2) in comparison to doxycycline alone.

Neuroinflammation has been implicated in the pathogenesis of West syndrome (WS). Inflammatory cytokines, including interleukin-1β(IL-1β), have been reported to be associated with epilepsy. However, the assessment of cytokine changes in humans is not always simple or deterministic. This study aimed to elucidate the immunological mechanism of WS. We examined the intracellular cytokine profiles of peripheral blood cells collected from 13 patients with WS, using flow cytometry, and measured their serum cytokine levels. These were compared with those of 10 age-matched controls. We found that the WS group had significantly higher percentages of inter IL-1β, interleukin-1 receptor antagonist (IL-1RA)-positive monocytes, and interferon gamma (IFN-γ) in their CD8+ T cells than the control group. Interestingly, the group with sequelae revealed significantly lower levels of intracellular IFN-γ and IL-6 in their CD8+ T and CD4+ T cells, respectively, than the group without sequelae. There was no correlation between the ratios of positive cells and the serum levels of a particular cytokine in the WS patients. These cytokines in the peripheral immune cells might be involved in the neuroinflammation of WS, even in the absence of infectious or immune disease. Overall, an immunological approach using flow cytometry analysis might be useful for immunological studies of epilepsy.

Objectives: To evaluate the frequency of non-alcoholic fatty liver disease, the retinol serum levels, lipid profile, and insulin resistance in overweight/obese children. To relate these biochemical variables with the risk of this disease in the population studied. Methods: The study was cross-sectional and prospective, with 46 overweight/obese school children (28 female, 18 male; mean age 8.6 years). The control group consisted of 45 children, paired by age and gender. Hepatic steatosis, evaluated by ultrasound, was classified as normal, mild, moderate, or severe. Also evaluated were serum retinol levels; thiobarbituric acid reactive substances; lipid profile; and fasting glucose and serum insulin levels, used for the calculation of the Homeostasis Model Assessment. Results: Hepatic ultrasound alterations were found in 56.5% and 48,9% of the overweight/obese and control group children, respectively. Presence of obesity was associated with high levels of triglycerides (OR = 4.6; P = 0.002). In the studied children, the risk of steatosis was related to a trend to a higher percentage of retinol inadequacy (OR = 2.8; p = 0.051); there was no association with thiobarbituric acid reactive substances, lipid profile, or insulin resistance. Conclusions: The high frequency of non-alcoholic fatty liver disease in both groups, evaluated by hepatic ultrasound, in low-socioeconomic level children, independent of nutritional condition and without significant association with insulin resistance, emphasizes that especially in developing countries, other risk factors such as micronutrient deficiencies (e.g. vitamin A) are involved.

Introduction: Tuberculosis (TB) and especially resistant forms of it have a substantial economic burden on the community health system for diagnosis and treatment each year. Thus, investigation of this field is a priority for the world health organization (WHO). Cytokines play important roles in the relationship between the immune system and tuberculosis. Genetic variations especially single nucleotide polymorphisms (SNPs) impact cytokine levels and function against TB. Material and Methods: In this research SNPs in IFN-γ (+874 T/A) and IL-10 (-592 A/C) genes, and the effects of these SNPs on cytokine levels in a total of 87 tuberculosis patients and 100 healthy controls (HCs) were studied. TB patients divided into two groups: 1) 67 drug-sensitive (DS-TB) and 2) 20 drug-resistant (DR-TB) according to drug sensitivity test using polymerase chain reaction (PCR). For the genotyping of two SNPs, the PCR-based method was used and IFN-γ and IL-10 levels were measured by ELISA in pulmonary tuberculosis (PTB) and control group. Results: In -592A/C SNP, only two genotypes (AA, AC) were observed and both genotypes showed statistically significant differences between DR-TB and HCs (p=0.011). IL-10 serum levels in PTB patients were higher than HCs (p=0.02). The serum levels of IFN-γ were significantly higher in DS-TB patients than that of the other two groups (p<0.001); however, no significant differences were observed for allele and genotype frequencies in IFN-γ +874. Conclusions: Our results suggest that the SNP at -592 position of IL-10 gene may be associated with the susceptibility to DR-TB. However, further investigation is necessary. Keywords: Polymorphism, IFN-γ, IL-10, tuberculosis, drug-resistant tuberculosis
