Summary: Macrophages deficient in PTPN2 promote a strong IL-22-driven immune response, leading to accelerated disease but faster clearance of Citrobacter rodentium infection. Deletion of PTPN2 in epithelial cells results in a failure to upregulate antimicrobial peptides and eliminate the infection. Macrophage-derived IL-22 plays a crucial role in the induction of protective immune responses in the intestinal epithelium.

Summary: The FADS mouse model, generated by specifically deleting Ikk2 in facial skin fibroblasts, exhibits similar ocular lesions to AKC in patients and can be used to examine the therapeutic effects of anti-AKC agents. Tear periostin, a novel biomarker for allergic conjunctival disease, is valuable for evaluating the efficacy of such treatments.

Summary: Mammalian carboxylesterase 1 (Ces1) enzymes play a vital role in metabolism, hydrolyzing numerous xenobiotics and endogenous lipids. This study identified a mouse strain lacking three Ces1 genes (Ces1c, Ces1d, and Ces1e), and demonstrated that this deficiency impaired drug and lipid metabolism, leading to altered body weight, inflammation, and lipid accumulation in adipose tissue and liver. These findings emphasize the importance of Ces1 enzymes in maintaining metabolic homeostasis and suggest their potential role in obesity-related chronic inflammation and metabolic diseases.

Summary: Systemic juvenile idiopathic arthritis (sJIA) is an immune disorder with increasing reports of lung involvement in patients. A mouse model for sJIA showed lung abnormalities distinct from those seen in patients, indicating the importance of monitoring lung disease during systemic inflammation. The model provides a tool to explore the underlying mechanisms of lung pathology in an autoinflammatory disease context.

Summary: The study showed that Citrus unshiu leaf extract has anti-inflammatory properties by inhibiting proinflammatory cytokines and chemokine secretion from macrophages. Oral administration of the extract also reduced proinflammatory cytokines levels and increased anti-inflammatory cytokine levels in a mouse model of systemic inflammation. Additionally, the extract decreased the secretion and gene expression of proinflammatory proteins in the liver and spleen of the model mice.

Summary: The study identified antimicrobial resistant bacteria in commercial poultry farms, including resistance to last-resort antibiotics. These resistant bacteria were found to be potentially transferable among different bacterial strains. The presence of multidrug resistant bacteria in both conventional cage and cage-free poultry indicates the need for further research to develop strategies for mitigation.

Summary: The study presents a tunable, stabilizer-free PLGA nanoparticle formulation capable of encapsulating DNA with exceptional stability and biocompatibility. Various PLGA formulations were tested for stability, with P4 exhibiting the highest stability under physiological conditions. The nanoparticles were found to be as stable as those made with toxic stabilizers like PVA, but significantly less cytotoxic.

Summary: Non-typhoidal Salmonella (NTS) is a major global health concern, particularly in areas affected by malnutrition and comorbidities like HIV and malaria. This study identified a unique NTS isolate named UGA14 that displayed novel plasmid, pseudogene and resistance features, as well as the ability to ferment both lactose and sucrose, highlighting the co-evolution of plasmid-mediated metabolic traits and cephalosporin resistance in NTS strains. The findings emphasize the importance of combined genomic and phenotypic approaches in detecting and characterizing atypical NTS isolates to inform efforts in controlling invasive and antimicrobial resistant NTS.

Summary: This study genetically engineered a lung cell line to create fluorescent reporters for signaling pathways and evaluated the effects of pathogenic and non-pathogenic bacteria on these pathways. The results showed that pathogenic bacteria induced more significant cell death and disruption of signaling compared to non-pathogenic bacteria. This study demonstrates the potential of using ERK-Fra1 signaling as a rapid and sensitive screening method for pathogenic bacteria.
