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.

Background and Aim: The aryl hydrocarbon receptor (AhR) plays a pivotal role in spermatogenesis through its regulatory functions in redox balance and gene expression. This study aimed to investigate the effects of resveratrol (RES), a polyphenolic AhR modulator, and CH223191, a selective AhR antagonist, on male reproductive function in rats by assessing sperm quality, oxidative stress, testicular histopathology, and AhR gene expression. Materials and Methods: Forty adult male rats were randomly divided into four groups: (i) Control, (ii) dimethyl sulfoxide (vehicle), (iii) RES (100 mg/kg i.p., twice weekly), and (iv) AhR⁻ (CH223191, 10 mg/kg i.p., twice weekly), treated for 60 days. Post-treatment, sperm motility, survival, viabi
