The commensal bacterium Lactiplantibacillus plantarum is recognized for its ability to cause a state of innate immune memory in monocytes, characterized by the tolerogenic phenotype and lowered pro-inflammatory responses. This study provides an extensive re-examination of the transcriptomic dataset originating from human CD14 + monocytes primed with live or heat-killed L. plantarum (GSE159496). Using a computational approach, 1,954 differentially expressed gene calls that corresponded to 1,397 unique genes were obtained through three pairwise comparisons. In addition, several novel biological pathways that were not investigated in the original study were discovered. Priming with live L. plantarum resulted in a marked downregulation of the complement system (12.5% decrease in its module score, p < 0.001), indicating an important mechanism of immune evasion. Additionally, a significant alteration of the circadian rhythm pathway was revealed, indicating its connection to metabolic time management in sustaining long-term immune tolerance. Toll-like receptor (TLR) signaling was coordinately repressed, with 17 pathway genes—including the receptors TLR2 and TLR8—significantly downregulated in live primed cells (p.adjust = 3.0 × 10–6 ). Other significantly modulated novel pathways included a downregulation of glycosylation and post-translational modifications (−13.2%, p < 0.01) and an upregulation of amino acid sensing/mTOR signaling (+11%, p < 0.001) and xenobiotic detoxification (+12%, p < 0.01). These findings point to a multi-layered adaptive response where L. plantarum not only dampens canonical inflammatory signaling but also actively remodels cellular processes related to pathogen recognition, metabolic sensing, and stress responses. This reanalysis provides a more granular model of probiotic-induced immune memory.

The spread of novel coronavirus disease (COVID-19) has resulted in chaos around the globe. The infected cases are still increasing, with many countries still showing a trend of growing daily cases. To forecast the trend of active cases, a mathematical model, namely the SIR model was used, to visualize the spread of COVID-19. For this article, the forecast of the spread of the virus in Malaysia has been made, assuming that all Malaysian will eventually be susceptible. With no vaccine and antiviral drug currently developed, the visualization of how the peak of infection (namely flattening the curve) can be reduced to minimize the effect of COVID-19 disease. For Malaysians, let’s ensure to follow the rules and obey the SOP to lower the
Background: The aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor historically recognized for its role in the regulation of toxicity mediated by environmental chemicals. Recent research points to AhR's critical participation in male reproductive physiology, particularly in spermatogenesis, hormone signaling, and the maintenance of sperm quality. Both endogenous ligands (e.g., dietary and gut microbiota-derived metabolites) and exogenous pollutants (e.g., dioxins and benzo-α-pyrene) influence AhR-mediated pathways, making it a key link between environmental exposures and male fertility. Results: This review highlights AhR's influence on the male reproductive system, emphasizing the role of endogenous AhR ligands an
... Show MoreVitamin D receptor (VDR) is a nuclear transcription factor that controls gene expression. Its impaired expression was found to be related to different diseases. VDR also acts as a regulator of different pathways including differentiation, inflammation, calcium and phosphate absorption, etc. but there is no sufficient knowledge about the regulation of the gene itself. Therefore, a better understanding of the genetic and epigenetic factors regulating the VDR may facilitate the improvement of strategies for the prevention and treatment of diseases associated with dysregulation of VDR. In the present investigation, a set of databases and methods were used to identify putative functional elements in the VDR locus. Histone modifications, CpG I

It has been reported that the progression of CP causes shifting of the balance between bone formation and resorption toward osteoclastic resorption, and this will lead to the release of collagenous bone breakdown products into the local tissues and the systemic circulation. Cross-linked N-telopeptide of type I collagen (NTx) is the amino-terminal peptides of type I collagen which is released during the process of bone resorption. This study was conducted to determine the effects of nonsurgical periodontal therapy on serum level of NTx in type 2 diabetic patients

HBV and HCV are the major causes of chronic liver diseases throughout the world, and constitute a major global health risk. There is accumulated evidence that the imbalance of proinflammatory and anti-inflammatory cytokine production may play an important role in the pathogenesis of viral hepatic infections and may influence the clinical outcome and disease progression. This study was undertaken to analyze the circulating levels of Tumor Necrotic Factor (TNF-α) and Th2 cytokine IL-10 in patients infected with Hepatitis B and C virus. The study population consisted of 30 patients with chronic HBV, in addition to other 30 patients with chronic HCV infection were recruited on their first examination at the Al-Kindy General Hospital in Baghdad
... Show MoreChromium (Cr), a first-series transition metal with a standard atomic mass of approximately 52 g/mol, plays a sophisticated role as an essential trace element in human and animal physiology. Characterized by its diverse oxidation states most notably the highly stable Cr3+ this micronutrient functions primarily as a biochemical potentiator of insulin action. Through the activation of the low-molecular-weight chromium-binding substance, chromodulin, chromium amplifies insulin receptor tyrosine kinase activity, thereby facilitating efficient glucose uptake and the metabolism of carbohydrates, proteins, and lipids. Beyond glycemic control, chromium serves as a critical modulator of lipid profiles, stimulating lipase activity to reduce very low-
