Summary: Human guanylate-binding proteins (hGBPs) are associated with intracellular Mycobacterium tuberculosis (Mtb) and Listeria monocytogenes (Lm) through disruption of phagosomal membranes. The formation of puncta structures by hGBP1 is dependent on GTP-binding and isoprenylation and is required for endolysosomal integrity and repair.

Summary: This study aimed to determine the difference in survival and antimicrobial susceptibility of L. monocytogenes and other Listeria species under different food processing environment stressors. The results showed that L. monocytogenes strains were more tolerant to environmental stresses. Additionally, anaerobic incubation after exposure to stressors rendered Listeria species more resistant to antimicrobials. Different stressors induced an increase in the minimum inhibitory concentrations of certain antimicrobials. These findings have important implications for controlling Listeria species in the food industry.

Summary: Listeria monocytogenes is a foodborne pathogen that can survive in harsh food processing environments. The use of bacteriocins as a natural alternative to control this pathogen has been hindered by the emergence of resistant strains. This study compares the properties of susceptible and resistant strains, including growth, antibiotic susceptibility, cell morphology, virulence factor expression, and biofilm formation. The results contribute to the understanding of bacteriocin-resistance development in L. monocytogenes and its implications for the use of these peptides as biopreservatives.

Summary: Listeria monocytogenes is a dangerous foodborne pathogen that poses a significant threat to the food industry. A data analysis approach was used to study its stress response, virulence, and antimicrobial resistance by creating protein interaction networks. Key proteins were identified, including sigB, flaA, cheA, cheY, and lmo0693, which show high potential as targets for combating L. monocytogenes. These findings offer new directions for improving food preservation methods and developing treatments for L. monocytogenes.

Summary: In this study, the response of Listeria monocytogenes exposed to linalool was explored using iTRAQ-based quantitative proteomics analysis to uncover the mode of action and drug targets of linalool against LM. A total of 445 differentially expressed proteins were identified, with 31 significantly enriched gene ontology functional categories and 60 significantly enriched biological pathways. The analysis suggested that cell membranes, cell walls, nucleoids, and ribosomes might be the targets of linalool against LM.

Summary: According to the study, the nutrition status affects the adhesion ability and biofilm formation of Listeria monocytogenes. Nutrient deficiency can enhance the adhesion and biofilm formation of the bacteria, and also lead to changes in the expression of critical biofilm-associated genes. These findings are important for understanding the spread and control of Listeria in food processing.

Summary: Research shows that DegU plays a vital role in heat resistance in L. monocytogenes, sensing heat stress through autoregulation and upregulating the production of heat-shock proteins. DegU can also directly regulate the expression of specific operons, thus regulating heat resistance in L. monocytogenes.

Summary: The combination of lactate as an antimicrobial agent and high-pressure processing (HPP) as a lethal treatment is an effective strategy for controlling L. monocytogenes in cooked meat products. The molecular mechanisms underlying the protective effect of lactate involve promoting shifts in pathogen metabolism and membrane properties, enhancing resistance to HPP. This study provides insights into the adaptive responses of L. monocytogenes to lactate and HPP, contributing to the understanding of the piezo-protective effect of lactate.

Summary: This study aimed to conduct a meta-analysis of Listeria monocytogenes response to sanitizer treatments. The results showed that environmental factors such as sanitizer concentration, temperature, and treatment time affected the average log-reduction of L. monocytogenes. L. monocytogenes exhibited strong resistance to citric acid and sodium hypochlorite but had low resistance to electrolyzed water. The physical and chemical properties of the contaminated or inoculated matrix or surface also influenced the sanitizer effectiveness.

Summary: Listeria monocytogenes is a foodborne pathogen that can form biofilms on various surfaces and express different genes in biofilm and planktonic cells, which could affect its stress tolerance and virulence. This study investigated the expression of ten key stress response and/or virulence-related genes in three different strains of L. monocytogenes and found strain-dependent differential gene expression between biofilm and planktonic cells, suggesting the importance of considering strain variability in studies and eradication methods of pathogenic biofilms.

Summary: This study highlights the importance of base excision repair (BER) for Listeria monocytogenes virulence and survival during host colonization. By deleting specific DNA glycosylases and apurinic/apyrimidinic endonucleases, researchers found that certain mutants were attenuated in virulence in a mouse model and showed reduced colonization in the liver and spleen.

Summary: Researchers used metagenomics and transcriptomics to study microbial dynamics in a 15-year old bioreactor with benzene as the main carbon source. Their findings revealed that most members of the microbial community likely feed on metabolic leftovers or necromass, while only a few are capable of degrading benzene. These benzene degraders are essential for maintaining species richness and ecosystem stability within the community.

Summary: A computational approach using metabolic gene annotation was used to rapidly predict putative interactions between members of urinary tract infection microbial communities, revealing that Enteroccus spp. were most complemented in its metabolism by other community members. Experimental supplementation of predicted metabolites confirmed the increase in population density of UTI Enterococcus isolates. This method shows promise as a rapid in silico screening tool for predicting metabolic interactions in microbial communities.

Summary: This study found that high-risk human papillomavirus 16 infection is associated with activation of the mitogen activated protein kinase (MAPK)/ERK signaling pathway and induction of canonical autophagy. Additionally, the expression of dual-specificity phosphates 5 (DUSP5) is repressed by HPV16 E7. These findings suggest that DUSP5 may serve as a potential therapeutic target for cervical cancer.

Summary: This study demonstrates that c-di-GMP can stimulate immune responses and reduce MRSA infections by enhancing the secretion of antimicrobial peptides and chemokines. In a mouse skin wound infection model, pre-treatment with c-di-GMP significantly reduced bacterial colonization and promoted inflammatory cell infiltration, making it more difficult for MRSA to establish an infection.

Summary: This study comprehensively analyzed the cortex of vanishing white matter (VWM) patients using high-resolution mass spectrometry-based proteomics and immunohistochemistry. The findings revealed a large number of differentially expressed proteins in the VWM cortex, forming a major protein interaction network. Gene ontology analysis further indicated enrichment for cellular metabolism, particularly mitochondrial activity. Importantly, the study identified astrocytic involvement in the cortical pathology of VWM, with morphological changes and decreased complexity observed in VWM cortical astrocytes compared to control cells. These astrocytes were found to be immature and non-reactive. These insights into cortical involvement in VWM have significant implications for the development of therapeutic strategies.
