Abstract

Background: Carbonic anhydrases (CAs) are metalloenzymes which catalyze the reversible hydration/dehydration reaction of CO2, in order to maintain the cell homeostasis. These enzymes are found in various tissues and involve in a number of different physiological processes, including ion transport, acid-base balance, bone formation, and gluconeogenesis. Objective: To examine the specific activity of CA and to observe the liver tissue respond to oxidative stress by measured the malondialdehyde (MDA) concentration, in rat liver tissue induced by chronic systemic hypoxia for 1, 3, 5, 7, and 14 days of hypoxia. Results: The study showed that the activity of CA induced by chronic systemic hypoxia significantly increasing at early exposure to the hypoxic condition, at day 1 and days 3 of hypoxia (0.281 and 0.262 nmol/mg protein/minute compared to control 0.155 nmol/mg protein/minute) (p<0.05). No statistical difference at treatments of hypoxia 5, 7, and 14 days. The concentration of MDA also increased significantly on day 3 of liver tissue hypoxia (0.013 nmol/mg compared to control 0.009 nmol/mg liver tissue) (p<0.05), and no statistical differences at day 1, 5, 7, and 14 days of hypoxia. Conclusion: There was damage of membrane cells affected by oxidative stress in the liver tissue of rats induced by chronic systemic hypoxia.

Abstract

Background: Preeclampsia is one of the factors causing the high maternal mortality rate. The risk of morbidity and mortality is higher in Early Onset Preeclampsia (EOPE). Failure of spiral artery remodeling can cause oxidative stress that can inhibit placental development and increase trophoblast apoptosis. Objective: This study aims to analyze the oxidative stress and apoptosis of EOPE placentas. Methods: This study is an observational study with a cross-sectional design. A total of 31 EOPE placentas and 31 normal term placentas were used to measure the concentration of malondialdehyde (MDA) and the relative mRNA expression of FOXO3 and CASP3 using the spectrophotometric and RT-qPCR methods. Results: There was no difference in MDA concentration (p = 0.580) and FOXO3 (p = 0.467) and CASP3 (p = 0.243) mRNA expression in the normal and EOPE groups. There was a strong positive correlation between FOXO3 and CASP3 mRNA expression in the normal (p= 0.0001; r = 0.938) and EOPE groups (p = 0.0001; r = 0.855). There was no correlation between MDA concentration to FOXO3 (p = 0.124; r = 0.282) and CASP3 (p = 0.569; r = 0.106) mRNA expression in normal placenta. There was positive correlation between MDA concentration to FOXO3 (p = 0.016; r = 0.429) and CASP3 mRNA expression in EOPE placenta (p = 0.028; r = 0.395). Conclusion: These results indicate that cell integrity is still maintained through the autophagy process and the level of apoptosis in the EOPE placenta is regulated by ROS through FOXO3.

Abstract

Asthma is a major health problem and one of the leading causes of death in the world. The prevalence of asthma in Indonesia is high, with a recurrence >50%. Allergic sensitization in asthma is mainly caused by house dust mite (HDM) allergens, both from the mite’s body and its contaminants (e.g., lipopolysaccharides). HDM allergens stimulate several pathways in the innate immune response based on the HDM allergen groups that sensitize them. The innate immune response to HDM allergen exposure occurs when pattern recognition receptors (PRRs) recognizes the allergen, thereby stimulating respiratory epithelial cells to release cytokines, namely, thymic stromal lymphopoietin (TSLP), interleukin-25 (IL -25), and IL-33. The release of IL-25 and IL-33 activates group 2 innate lymphoid cells (ILC2) to release Th2-type cytokines (i.e., IL-5 and IL-13), resulting in allergic airway inflammation via IgE secretion by B cells, recruitment of eosinophils, and respiratory tract remodeling. Dendritic cells induce an adaptive immune response through Th2 activation in the sensitization and effector phases. Other mediators that contributed to the innate immune response include C-C motif chemokine ligand 20 (CCL-20) and granulocyte-macrophage colony-stimulating factor (GM-CSF). A deeper understanding of the components and mechanisms involved in innate immunity against HDM allergens creates the potential to develop alternative therapeutic targets for allergic asthma treatment.Keywords: house dust mite allergens, innate immunity, allergic asthma, respiratory epithelium, inflammatory cytokines

Abstract

The gastrointestinal (GI) tract represents our most intimate contact with the external environment. The GI tract responsible for extracting the appropriate nutrients we need to thrive, maintaining an appropriate balance of helpful and harmful microbes, and acting as a conduit for waste removal. In essence, the extracellular matrix of gut mucosal biofilm is a complex network of microbes and their secretions, as well as the host's secretions and signals (mainly mucus/mucin). Mucin, bacterial polysaccharides, and protein combine to form a unique mucosal biofilm that serves as a home for a variety of commensal and pathogenic organisms in the host. Maintaining proper mucosal barrier function is vital for both GI and systemic health. The lumen of the gut contains numerous entities that should never reach the bloodstream or lymphatic system. The mucosal barrier's integrity is maintained by a single layer of tightly fitted columnar epithelial, and more than 70% of the immune system components are closely associated with the GI tract.

Abstract

Background: Maternal exposure to cigarette smoke during pregnancy and lactation might harmful for the fetus. The smoke contains many free radicals that could be eliminated by antioxidant. This study aimed to investigate the effect of Spirulina platensis ethanol extract as antioxidant against cigarette smoke exposure during pregnancy until lactation by assessing oxidative stress markers in neonatal brain tissues. Methods: The experimental study used 26 offspring divided into four groups: (C) = offspring of maternal control group; (Cg) = offspring of maternal exposed to cigarette smoke; (CgSp) = offspring of maternal given spirulina and exposed to cigarette smoke; and (Sp) = offspring of maternal given spirulina only group, during gestation and 9 days lactation (30 days). Each group consisted of 6 offspring obtained from 2 adult females mated with male Sprague-Dawley rats. The exposure of cigarette smoke was 4 burn cigarettes/day for 30 days. The dose of extract was 200 mg/kg BW. The offspring were sacrificed, and the brain tissues were taken for MDA, MnSOD activity, as well as catalase activity, carbonyl, and GSH. Results: There was no significant differences in MDA level between groups. The carbonyl, SOD, and catalase activity did not differ between the control and smoked group. Conclusion: Exposure of four burned cigarettes smoke per day during pregnancy, and 9 days of lactation did not trigger oxidative stress. However, the effect of Spirulina platensis administration on rat offspring brain could not be analyzed.

Abstract

Asthma is the most frequent noncommunicable disease and one of the leading causes of years lived with disability. Asthma has a severe impact on a patient's life, being able to disturb the activities of both children and adults. The morbidity and mortality of asthma may depend on the severity and progressiveness of the symptoms experienced by the patient. Different and complex pathomechanisms underline the pathology of asthma, in which the regulation of innate and adaptive immune responses plays a role. There is a complex interaction between immune cells including chemokines involved in the pathogenesis of asthma. Immune cell trafficking is orchestrated by a family of small proteins called chemokines. Leukocytes express cell-surface receptors that bind to chemokines and trigger transendothelial migration. This review article outlines the main role of chemokines in inflammatory reactions that occur in allergic asthma, based on the latest literature studies that have been published previously. The allergic reaction in asthma expresses various chemokines and their receptors. Chemokines including eotaxins (CCL11, CCL24, and CCL26), CCL2, CCL5, CCL17, and CCL22 regulate immune cells that under pathological conditions travel to the inflammatory site, mainly in the lung, to protect the body from pathogen invasion. Chemokines are released by a number of immune cells such as monocytes, dendritic cells, mast cells, and epithelial cells in the airway. The biological effects of chemokine production are enhanced by secreted cytokines when an allergic reaction occurs in asthma, such as IL-4, IL-5, and IL-13. Chemokines cause an accumulation of different inflammatory cells at the site of inflammation, which ultimately results in tissue damage to the airway. The inhibition of the reactions evoked by the interaction between chemokines and their receptors is considered a candidate for the development of potent therapeutic drugs for asthma in the future.

Abstract

Several studies have predicted the molecular interactions of the active ingredient of Spirulina platensis as an anti-inflammatory compound. However, these interaction studies did not review the modulation of the NF-κB activation pathway, which involves various factors. This study demonstrated the potential of the bioactive compounds of S. platensis for modulating immune function by reducing inflammation through the inhibition of the NF-κB activation pathway. Phycocyanobilin was predicted to have good potential for molecular docking with multisubunit IκB kinase (IKK)1/IKKA, IKK2/IKKB, NF-κB-inducing kinase, and the IκBα/NF-κB complex. Furthermore, β-carotene exhibited good potential for interactions with NF-κB essential modulator/IKK and the NF-κB complex, and α-glucan had the potential for interactions with COX-2. Therefore, supplementation with S. platensisand its bioactive compounds is expected to provide optimal benefits.

Abstract

Tuberculosis is caused by Mycobacterium tuberculosis infection. During M. tuberculosis infection, there is a decrease in the partial pressure of oxygen in the granuloma microenvironment, which causes the hypoxia-inducible factor (HIF) to become stable. HIF functions as a transcription factor that regulates the expression of genes crucial for metabolic adaptation in hypoxic conditions. Recent research suggests that HIF plays a vital role in infectious and inflammatory conditions. Several studies have demonstrated that HIF signaling can enhance macrophages antimicrobial activity and bactericidal effect against M. tuberculosis, such as increasing macrophage autophagy, enhancing the effects of rifampicin, inhibiting p38 MAPK signaling, enhancing the regulation of effector antimicrobial pathways mediated by human β defensin 2 (hBD2) and vitamin D receptor (VDR), redirecting energy metabolism to glycolysis, and producing various cytokines. All these responses ultimately result in the inhibition of intracellular M. tuberculosis growth. HIF has therapeutic implications, potentially being a new candidate for host-directed therapy as a complement to existing antituberculosis drugs. Understanding the role of HIF in macrophages during M. tuberculosis infection and comprehending the host-pathogen relationship with M. tuberculosis is advantageous for developing future therapies.Keywords: Mycobacterium tuberculosis, macrophages, hypoxia-inducible factor

Abstract

Pro- and anti-inflammatory mediators need to be released in a balanced way to maintain a healthy state as we age. One important regulatory element in the equilibrium of pro- and anti-inflammatory mediators is NF-κB. The purpose of this study was to examine how S. platensis affected the control of inflammatory mediators in young, healthy, emerging adults and adults in rats. In this investigation, 200 mg/kg BW of S. platensis extract was administered to six groups of male Wistar rats, ages 12, 18, and 24 weeks, along with a control group. In both the treatment and control groups, NF-κB p65 protein expression was lower at 24 weeks than it was at 12 and 18 weeks. TNF-α and COX-2 proteins were lower in the treatment group than in the control group. All age groups in the treatment group had higher levels of IL-10 protein than the control group. The quantity of NF-κB p65 was positively correlated with COX-2 and TNF-α. By raising the concentration of NF-κB p65, the ethanolic extract of S. platensis altered a mediator of cellular immunity. A decrease followed this in TNF-α and COX-2 and a rise in IL-10 in the rat spleen at different ages.
