- Erythroleukemia is a malignant hematological disorder often accompanied by severe immunosuppression, with T cell dysfunction playing a central role. Gastrodin, which is derived from Gastrodia elata, has been proven to possess various pharmacological activities such as neuroprotection and immunomodulation. However, whether it can effectively improve the immune function in erythroleukemia has not been reported. Our results demonstrated that gastrodin treatment significantly alleviated splenomegaly and inhibited the malignant progression in erythroleukemia mice. Moreover, it markedly enhanced the proliferative capacity of splenic T cells and promoted the secretion of immune - related cytokines. Mechanistically, gastrodin upregulated the expression of key molecules in the T cell receptor signaling pathway, including LCK, ZAP-70, ITK, PKC, IKK, and NFκB, at both the mRNA and protein phosphorylation levels. Notably, through integrated bioinformatics analysis, molecular docking, and cellular thermal shift assays, we found that gastrodin exhibits moderate interaction with the transcription factor Fli-1 in erythroleukemia. Collectively, this study provides the first evidence that gastrodin enhances splenic immune function in erythroleukemia by modulating the T cell receptor (TCR) signaling pathway. Cellular thermal shift assay identified Fli-1 as a protein capable of physically interacting with gastrodin, although its functional contribution remains to be further explored. These findings highlight gastrodin as a promising immunotherapeutic candidate for erythroleukemia. - Source: PubMed

Cheng ShaXu YingjiangWang JianpingYu JiaHu LiangliangLiu JimingLuo Heng - Chimeric antigen receptor (CAR)-T cell therapy has emerged as a transformative cancer immunotherapy, employing genetic engineering to express CARs in patient T cells. CARs are composed of a single-chain variable fragment (scFv), hinge, transmembrane, and intracellular signaling domains. While scFv directly recognizes tumor-associated antigens, the hinge domain connects the scFv to intracellular signaling domains, determining the formation of immunological synapse (IS). Because IS is critical for CAR activation, optimizing hinge length is crucial for successful CAR-T cell therapy. Here, we developed a novel dimerization-dependent fluorescent protein (ddFP)-based IS biosensor, named CAR-D, to investigate hinge length effects on CAR activation. CAR-D consists of a CAR fused to ddFP-A and a ZAP70-tSH2 domain fused to ddFP-B. Upon CAR engagement with the target antigen, CAR phosphorylation recruits ZAP70-tSH2, triggering ddFP-A/ddFP-B dimerization and generating a fluorescent signal that reports CAR activation at the IS in real time. Using the CAR-D system, we assessed CARs with different hinge lengths targeting distinct epitopes of two tumor-associated antigens, mesothelin (MSLN) and HER2, and determined threshold hinge lengths for CAR activation. Our results revealed a strong correlation between threshold hinge length and the distance from scFv to the target epitope, implying that hinge length optimization is crucial for effective CAR-T cell therapy. Furthermore, the CAR-D system provides a valuable tool for predicting CAR efficacy and guiding future CAR engineering strategies. - Source: PubMed

- Inositol 1,4,5-trisphosphate receptor-interacting protein-like 1(ITPRIPL1) has recently been implicated in tumor-immune regulation, yet its tumor-type specificity and clinical relevance in gastrointestinal malignancies remain unclear. Here, we performed an integrative analysis of ITPRIPL1 across stomach adenocarcinoma (STAD), colon adenocarcinoma (COAD), rectal adenocarcinoma (READ), and esophageal carcinoma (ESCA) using bulk transcriptomics, immune pathway analyses, survival modeling, single-cell RNA sequencing, immunofluorescence validation, and therapeutic correlation analyses. Although ITPRIPL1 was upregulated across gastrointestinal cancers, its prognostic significance was highly tumor-specific, with elevated expression consistently predicting unfavorable survival only in STAD. In gastric cancer, ITPRIPL1 expression was closely associated with immune-related pathways and genomic instability features, and its prognostic association varied across immune contexts, particularly according to CD8⁺/CD4⁺ T-cell abundance, with an exploratory association also observed for zeta-chain-associated protein kinase 70 (ZAP70) expression. Single-cell and immunofluorescence analyses demonstrated preferential enrichment of ITPRIPL1 in T cells and tumor-adjacent immune structures. Notably, Exploratory analyses further showed that higher ITPRIPL1 expression was associated with favorable survival outcomes in selected external pretreatment immunotherapy cohorts and with lower IC50 values for several agents in cancer cell-line pharmacogenomic datasets. Collectively, these findings identify ITPRIPL1 as an immune-associated biomarker with primary clinical relevance in gastric cancer. - Source: PubMed

Lyu YahuiLyu HanzhangGuo GuodongZhao HongmeiLin WeitengWang YouqingChen HongHuang QiXue FangqinWang NingLin JinlanTian Yue - Intrauterine growth restriction (IUGR) is a leading cause of maternal and neonatal morbidity and mortality, particularly in low- and middle-income countries. Placental transcriptomics data were analysed to mapped dysregulated pathways via STRING-based PPI networks, identifying hubs and validating pesticide targets by molecular simulations. Rank-based prioritization identified IL7R, LCK and ZAP70 as top hub proteins driving placental dysfunction with cypermethrin exhibiting the lowest binding affinities across them (docking scores: -7.7, -8.7, -9.3 kcal/mol, respectively). Molecular dynamics simulations confirmed the stability of these docked complexes, while toxicity profiling indicated genotoxic potential for permethrin and high aquatic toxicity for deltamethrin. Thus, we show the critical molecular mediators linking pyrethroid exposure to IUGR, suggesting further experimental validation to support maternal health risk assessment. - Source: PubMed
