The Profile of Interferon-γ (IFN-γ) and Interleukin-10 (IL-10) in Pulmonary Tuberculosis Patients

Introduction: Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis and becomes the main health problems in the world and in Indonesia, as well. The microorganism itself is an intracellular pathogen. The control of tuberculosis infection depends on cell-mediated immunity involving activated macrophages, T cells, and cytokines. The balance and dynamic changes between Th1 cytokine and Th2 cytokine refl ect the immune response of host and infl uence the clinical manifestation of the disease.Objectives: This research was designed to study the profi le and interaction of IFN-γ (Th1 cytokine) and IL-10 (Th2 cytokine) of pulmonary tuberculosis (PTB) patients in endemic area.Methods: Peripheral blood mononuclear cells of 23 pulmonary TB patients and 16 healthy persons was cultured and stimulated by phytohaemagglutinin (PHA) to investigate the ability to secrete IFN-γ and IL-10.Result: The result showed that there was a decreased of IFN-γ response to PHA in PTB patients, suggesting the defi ciency of general immune capacity in PTB. In contrast, IFN-γ secreted by specifi c antigen was higher in PTB patients which minimal lung lesion was higher than moderate-far advanced. It is related to IFN-γ roles as immunomodulator in cellular immunity and immunoprotectant through stimulated antimicrobial capacity in macrophage. In fact, IL-10 response to PHA and M.tuberculosis antigen in PTB patients was lower than that of in healthy persons; moderate-far advanced lung lesion was the lowest. It was probably refl ecting their poor general conditions. Paired distribution between IFN-γ and IL-10 pointed out the leaning of negative interaction. It refl ected the existence of counterpart/cross regulation between IFN-γ(Th1 cytokine) and IL-10 (Th2 cytokine).Conclusion: In conclusion that specifi c immune response of PTB is related to the degree of lung lesion. This study also provides the balance of Th1 cytokine and Th2 cytokine in relation to TB.Key words: tuberculosis, immune response, IFN-γ, IL-10, lung lesio

The Red Fruit (Pandanus Conoideus Lam) Ethanol Extract Decreased the Nitric Oxide (NO) Levels of Plasmodium Berghei Infected Swiss Mice Malaria Model but not the Interferon Gamma (IFN-γ)

ABSTRACTIntroduction: The immunity against malaria infection was very complex, involving humoral immunity and cellular immunity.  One of the methods to improve body immune response was using antioxidant. Red fruit (Pandanus conoideus Lam) containing carotenoid and tocopherol that have antioxidants effects increase phagocytosis activity of macrophage and proliferation activity of lymphocyte as immune response againts parasite infection.Objectives: This study was intended to know the effect of red fruit (P. conoideus Lam) ethanol extract on IFN-γ and nitric oxide (NO) levels in Plasmodium berghei infected Swiss mice malaria model.Methods: This quasi experimental study used post test only control group design. Sixty eight-week aged male Swiss mice were devided into 6 groups. Group I was not given red fruit ethanol extracts neither infected by P.berghei, group II was given 260mg/kg/day of red fruit ethanol extracts, and it was not infected by P.berghei, groups III, IV and V were given red fruit ethanol extracts at 130, 260 and 520mg/kg/day respectively and infected by P.berghei. Group VI was not given the extract, however it was infected by P.berghei as control group. The red fruit ethanol extracts or the carrier was given for 28 days and the mice were infected by P.berghei in the beginning of week 3. On the day 3 and 9 after infection, 2 mL blood was taken from 3 mice of each group for serum isolation.Results: There was not any significant difference (p>0.05) mean of IFN-γ levels in all groups neither on day 3 nor day 9 after infection. The nitric oxide levels mean of mice group which have received red fruit extracts at 130 and 260mg/kg/day on the day 9 and  in mice group which have received red fruit extracts 260mg/kg/day on day 3 were lower than they were in control group without any extract (group VI). However, the nitric oxide levels mean of mice group which have received 520mg/kg/day did not show any significant difference (p>0.05) compared with control group.Conclusion: The red fruit (P. conoideus Lam) ethanol extract did not show any significant effect on the IFN-γ levels, however at doses of 130 and 260mg/kg/day it decreased the nitric oxide level of P. berghei infected Swiss mice malaria model significantly. Keywords: Pandanus conoideus Lam, Interferon gamma (INF-γ), Nitric oxide (NO),  Plasmodium berghei, and Malaria ModelKeywordsPandanus conoideus Lam, Interferon gamma (INF-γ), Nitric oxide (NO), Plasmodium berghei, and Malaria Mode

The Effects of Exercise on Spleen Fibrosis and Macrophage Number in D-Galactose-Induced Aging Rat Model

Background: Spleen plays a role in human immune system as well as in recycling and filtering blood. The aging spleen is associated with fibrosis and impaired immune system, increasing individual vulnerability to getting infections. Regular physical activity is essential to maintain and enhance body fitness, endurance, and immune system.Objective: This study aimed to investigate the effects of mild and moderate-intensity treadmill exercise on the aging spleen by examining fibrosis and the number of macrophages in d-Galactose-induced aging rat models.Methods: Twenty-four male Wistar rats were randomly divided into four groups: G1 (control group), G2 (d‐Galactose, no exercise), G3 (d‐Galactose, low-intensity exercise), and G4 (d‐Galactose, moderate-intensity exercise). d-Galactose was administered intraperitoneally on day 0 and treadmill exercise was given for four weeks following the modified Brown et al. (2007) protocol. Spleens were histologically processed and stained for picrosirius red and against CD68+ antibody. Percentage of fibrosis fraction area and macrophage cell count were obtained using ImageJ, and the data were analyzed statistically using SPSS software.Results: The aging spleen did not show any differences in weight, length, and width among groups (P > 0.05). The administration of d-Galactose in rats causes fibrosis and an increased number of macrophages. Low and moderate-intensity treadmill exercise could not lower the percentages of fibrosis fraction area. However, the moderate-intensity treadmill exercise was effective in lowering macrophage number.Conclusion: Moderate-intensity treadmill exercise was effective in lowering macrophage cell count in the aging rat spleen induced by d-Galactose

Practical tips to adopt active lifestyle for university students during pandemic life: a narrative review

The Covid-19 pandemic worsened the physical inactivity pandemic and also increased sedentary behavior across the population, including university students. While physical inactivity and sedentary behavior are detrimental to health and academic performance, there is an urgent need to help university students to adopt an active lifestyle during post-pandemic life. This narrative review discussed current physical activity (PA) and sedentary behavior recommendations, practical tips for adopting an active lifestyle by applying PA doses using the frequency, intensity, time, and type (FITT) principle, and behavioral strategies to adopt and maintain an active lifestyle. Finally, several considerations related to the PA-related musculoskeletal injury and cardiovascular events risks were also discussed with examples from interventions during the pandemic in university settings

Ultradeep Sequencing for Detection of Quasispecies Variants in the Major Hydrophilic Region of Hepatitis B Virus in Indonesian Patients

Quasispecies of hepatitis B virus (HBV) with variations in the major hydrophilic region (MHR) of the HBV surface antigen (HBsAg) can evolve during infection, allowing HBV to evade neutralizing antibodies. These escape variants may contribute to chronic infections. In this study, we looked for MHR variants in HBV quasispecies using ultradeep sequencing and evaluated the relationship between these variants and clinical manifestations in infected patients. We enrolled 30 Indonesian patients with hepatitis B infection (11 with chronic hepatitis and 19 with advanced liver disease). The most common subgenotype/subtype of HBV was B3/adw (97%). The HBsAg titer was lower in patients with advanced liver disease than that in patients with chronic hepatitis. The MHR variants were grouped based on the percentage of the viral population affected: major, ≥20% of the total population; intermediate, 5% to <20%; and minor, 1% to <5%. The rates of MHR variation that were present in the major and intermediate viral population were significantly greater in patients with advanced liver disease than those in chronic patients. The most frequent MHR variants related to immune evasion in the major and intermediate populations were P120Q/T, T123A, P127T, Q129H/R, M133L/T, and G145R. The major population of MHR variants causing impaired of HBsAg secretion (e.g., G119R, Q129R, T140I, and G145R) was detected only in advanced liver disease patients. This is the first study to use ultradeep sequencing for the detection of MHR variants of HBV quasispecies in Indonesian patients. We found that a greater number of MHR variations was related to disease severity and reduced likelihood of HBsAg titer

Antifibrotics and Antioxidants of Chlorogenic Acid Inhibits Toll- Like Receptors-4 as Liver Fibrotic Marker

Introduction: Chlorogenic Acid (CGA) is an antifibrotic and antioxidant for fibrotic tissues. These double &nbsp;roles be able to inhibit or fibrotic tissues chains because of internal and external issues. &nbsp;For example, virus, bacteria or other pathogens and also by drugs, alcohol, cigarettes, etc. as external factor that affect quality of body tissues. Toll-Like Receptor-4 (TLR-4) as a marker fibrotic tissues.&nbsp; It is a key for researcher could be find out by expression performance. The aim of this study is to reveal the CGA as a candidate of antifibrotic &amp; antioxidant in liver fibrosis that induced by CCL4. &nbsp; &nbsp;Methods: This is a pure experimental research with a simple experimental design or post-test only control group design. The total 29 mices of 2.5-month-old&nbsp;male Swiss mices with weigh 35-40 gram divided into 6 group:&nbsp;3 groups of controls&nbsp;(injected by natrium chloride, CGA, and CCL4)&nbsp;and 3 groups of treated (injected by CGA&nbsp;doses 42 mg/kg, 63 mg/kg or&nbsp;84 mg/kg).&nbsp; Liver organ was used to examine the expression of TLR-4 by rt-PCR. This research revealed that expression of TLR-4 lower than the CCL4 control group (respectively, p=0.042; p=0.005; p=0.006; and p=0.001). Higher dose of&nbsp;CGA showed greater ability as anti-fibrotic through inhibit the expression of&nbsp; TLR-4. Some research found the expression of TLR-4 has been decreased by treatment of Clorogenic Acid (CGA). Conclusion: To sum up, CGA has double roles to repair liver fibrotic tissues. The greater doses of CGA, the stronger inhibition of TLR-4 expression

Update on Non-Alcoholic Fatty Liver Disease-Associated Single Nucleotide Polymorphisms and Their Involvement in Liver Steatosis, Inflammation, and Fibrosis: A Narrative Review

Genetic factors are involved in the development,progression, and severity of non-alcoholic fatty liver disease (NAFLD). Polymorphisms in genes regulating liver functions may increase liver susceptibility to NAFLD. Therefore, we conducted this literature study to present recent findings on NAFLD-associated polymorphisms from published articles in PubMed from 2016 to 2021. From 69 selected research articles, 20 genes and 34 SNPs were reported to be associated with NAFLD. These mutated genes affect NAFLD by promoting liver steatosis (PNPLA3, MBOAT7, TM2SF6, PTPRD, FNDC5, IL-1B, PPARGC1A, UCP2, TCF7L2, SAMM50, IL-6, AGTR1, and NNMT), inflammation (PNPLA3, TNF-α, AGTR1, IL-17A, IL-1B, PTPRD, and GATAD2A), and fibrosis (IL-1B, PNPLA3, MBOAT7, TCF7L2, GATAD2A, IL-6, NNMT, UCP, AGTR1, and TM2SF6). The identification of these genetic factors helps to better understand the pathogenesis pathways of NAFLD
