- Periodontitis (PD) and ulcerative colitis (UC) are two common chronic inflammatory diseases increasingly connected via the "oral-gut axis," yet their shared molecular mechanisms remain unclear. Oxidative stress, driven by excessive reactive oxygen species (ROS), represents a key pathogenic mechanism common to both PD and UC. In this study, we integrated transcriptomic datasets from patients with PD and UC to identify oxidative stress-related genes underlying their comorbidity. By combining weighted gene co-expression network analysis (WGCNA), machine learning, and single-cell RNA sequencing, we identified and validated a set of comorbidity-associated diagnostic biomarkers: CXCL1, XBP1, CD93, FYN, SELP, and CXCR4. These genes demonstrated high diagnostic accuracy across independent datasets, and gene set enrichment analysis (GSEA) revealed their involvement in inflammatory and immune-related pathways. Single-cell analysis further demonstrated endothelial-specific co-expression of SELP and CD93, highlighting their potential roles in intercellular communication and chronic inflammation. Moreover, molecular docking identified candidate therapeutic compounds with strong binding affinities for these targets. Collectively, our findings elucidate shared oxidative stress-driven mechanisms linking PD and UC and propose novel biomarkers and therapeutic targets for these interconnected diseases. - Source: PubMed

Wang LingxuGu QiuleDing XuTang ChunboWu Jin - B cell development relies on stringent checkpoints that ensure immune competence and eliminate autoreactive clones. Transitional B cells (B220CD93), which emerge from the bone marrow, migrate to the spleen and differentiate into follicular (FO) or marginal zone (MZ) B cells, a process governed by B cell receptor (BCR) signaling strength, metabolic fitness, and survival cues. Here, we identify Folliculin Interacting Protein 1 (Fnip1) as a key regulator of this developmental transition. Using conditional Fnip1-deficient mice (), loss of Fnip1 results in a developmental arrest at the transitional B220CD93 stage, severely limiting differentiation into FO and MZ B cells and leading to accumulation of a distinct enlarged CD19, RAG negative B cells. Fnip1 modulates BCR signaling thresholds and metabolic programming by regulating the AMPK/FLCN/TFEB and CD19/PI3K/Akt/mTORC1 pathways through restricting TFEB access to the nucleus. Using the MD4/mHEL/sHEL tolerance model, we show that Fnip1 is dispensable for negative selection but is essential for maintaining peripheral tolerance. Together, our findings define Fnip1 as a metabolic gatekeeper that integrates nutrient-sensing pathways with BCR signaling to orchestrate transitional B cell fate decisions, promote peripheral tolerance, and maintain immune homeostasis. - Source: PubMed

Park HeonCulbert RyanSakya DechenSilprasert Raynah RIritani Brian M - Chimeric antigen receptor (CAR) T cell therapy has transformed the treatment of B cell malignancies, but translation to acute myeloid leukemia (AML) has been hindered by on-target, off-tumor (OTOT) toxicity. In particular, endothelial cell (EC)-specific toxicity has limited clinical translation of promising leukemia stem cell-enriched targets such as CD93. Innovative strategies to mitigate EC damage while preserving antileukemic efficacy are needed. - Source: PubMed

Woodring TessKletzien Otto ASchlevensky KierstinSanchez-de-Diego CristinaVishwasrao PareshMahoney LaurenKerr Sheena CRichards Rebecca M - Lung cancer (LC) remains a leading cause of cancer-related mortality worldwide, and the limited efficacy of immunotherapy due to treatment resistance underscores the urgent need for new therapeutic strategies. In the present study, CD93-targeted poly(lactic-co-glycolic acid) (PLGA) nanoparticles encapsulating resveratrol (CD93-NPs@RSV) were developed to remodel the metabolic fitness of CD8 tumor-infiltrating lymphocytes. The nanoparticles were precisely engineered and characterized using dynamic light scattering, transmission electron microscopy, and in vivo imaging, which confirmed their stability and tumor-targeting capability. Mechanistic studies revealed that CD93-NPs@RSV suppressed CD93 expression, facilitated apoptosis-inducing factor (AIF) mitochondrial translocation, and activated oxidative phosphorylation (OXPHOS), thereby enhancing T cell function in the tumor microenvironment. Transcriptomic and proteomic analyses further confirmed regulation of the CD93-AKT-PAK5-AIF signaling axis. In a Lewis LC model, CD93-NPs@RSV significantly inhibited tumor progression and displayed strong synergy with anti-PD-1 therapy, resulting in improved survival outcomes. Collectively, our study demonstrates that CD93-NPs@RSV provide a powerful nanotechnology-driven approach to reverse immunotherapy resistance by reprogramming T cell metabolism. These findings establish a promising paradigm for precision cancer immunotherapy and underscore the translational potential of targeted nanomedicine in overcoming therapeutic bottlenecks in LC. - Source: PubMed

Jiang ZhouLi Yuning - Tumor metastasis represents a major determinant of prognosis in ovarian cancer. Accumulating evidence has demonstrated that the glycosylation of secretome proteins regulates cell communication in the tumor microenvironment, thereby affecting tumor metastasis; however, the underlying regulatory mechanisms remain unclear. In this study, we observed markedly elevated glycosylation levels in metastatic ovarian cancer and identified GALNT10 as a key glycosyltransferase that promotes EMT of ovarian cancer cells. Furthermore, GALNT10 enhances the extracellular secretion of IGFBP7 through O-GalNAc glycosylation modification at the T188 site. IGFBP7 subsequently interacts with the CD93 receptor on endothelial cells, leading to vascular remodeling characterized by abnormal vascular formation and impaired vascular maturity. Moreover, we identified the GALNT10 inhibitor Luteolin, which effectively suppresses ovarian cancer metastasis, modulates the immunosuppressive tumor microenvironment through tumor vascular-immune crosstalk, and exhibits synergistic effects with anti-PD1 therapy. Collectively, our findings indicate that GALNT10 facilitates ovarian cancer metastasis through the induction of tumor cell EMT and tumor vascular dysfunction, suggesting that GALNT10 inhibitors represent a promising avenue for the development of novel therapeutic strategies in ovarian cancer. - Source: PubMed
