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.

Folate-conjugation chemistry, either by direct ligand coupling or linker-assisted surface modification, have resulted in more selective receptor-based targeting, increased stability, and regulated chemotherapeutic release inside the tumor microenvironment. These nanosystems show increased penetration and selective absorption via FR-mediated endocytosis, which allows for deeper intratumoral distribution and more effective administration of chemotherapeutics and imaging agents. Recent advances in nanomedicine-based drug delivery systems with folate-functionalization shows promise for integrated GBM diagnosis and treatment.

Unlike classical checkpoint pathways that are predominantly interpreted through T cell-centered suppression, accumulating evidence indicates that VISTA exerts broader and highly context-dependent immunoregulatory functions, frequently centered on myeloid cells within the tumor microenvironment. In many malignancies, VISTA is preferentially enriched in tumor-associated macrophages, myeloid-derived suppressor cells, and dendritic cells rather than being uniformly expressed by tumor cells. This compartment-specific distribution has been linked to suppressive myeloid differentiation, impaired antigen presentation, altered inflammatory cytokine programs, T-cell dysfunction, and immune exclusion. Recent studies further suggest that VISTA biology is shaped by ligand context, tissue compartment, tumor acidity, and therapy-induced adaptation, supporting its role in resistance to conventional immune checkpoint blockade in selected settings. In this review, we summarize the structural and functional features of VISTA, its expression patterns in physiological and tumor contexts, its mechanistic role in shaping the tumor microenvironment, and the current landscape of VISTA-targeted therapeutic strategies. Key unresolved questions include which VISTA binding partners dominate in vivo, how cellular source and spatial localization determine biological and prognostic meaning, and whether early pharmacodynamic target engagement will translate into durable clinical benefit. Collectively, current evidence supports the view that VISTA should be considered not simply as another inhibitory receptor, but as a dynamically regulated, myeloid-centered checkpoint axis with translational relevance in checkpoint-refractory and immune-excluded tumors.

In addition to genetic alterations, metabolic reprogramming is a hallmark of HNSCC and contributes to tumor progression and treatment failure. The hepatocyte growth factor (HGF)/c-MET signaling pathway is frequently activated in head and neck squamous cell carcinoma (HNSCC), where it promotes tumor cell proliferation, invasion, and increased glucose metabolism. However, its contribution to the regulation of glutamine metabolism in HNSCC remains largely unexplored. Basal GLS-1 expression was compared between primary human oral keratinocytes (HOK) and HNSCC cell lines with distinct MET status (Detroit 562, FaDu, and SCC-154). Subsequently, HNSCC cell lines were stimulated with HGF, and GLS-1 expression was assessed by quantitative PCR and Western blotting. Functional effects were evaluated using wound-healing assays, enzymatic quantification of extracellular glutamine and glutamate, and Seahorse-based mitochondrial respiration analysis. GLS-1 was silenced using siRNA to determine its functional relevance. In addition, transcriptomic data from the TCGA-HNSC cohort were analyzed to evaluate the clinical association between MET signaling, MAPK/ERK pathway activity, and GLS1 expression. HGF stimulation selectively induced GLS-1 expression in MET-amplified Detroit 562 cells at both mRNA and protein levels, whereas MET wild-type cells remained largely unaffected. Mechanistically, HGF triggered robust ERK1/2 activation, and pharmacological inhibition of c-MET or ERK signaling abrogated GLS-1 induction. Functionally, HGF increased glutamine consumption, glutamate production, and mitochondrial respiratory capacity in a GLS-1-dependent manner, while GLS-1 silencing significantly impaired HGF-induced cell migration and mitochondrial respiration. Importantly, analysis of TCGA-HNSC tumors revealed significant correlations between MET expression, MAPK/ERK pathway activity, and GLS1 expression, supporting the clinical relevance of the identified signaling axis. Together, these findings identify GLS-1 as a downstream effector of HGF/c-MET-MAPK/ERK signaling in MET-amplified HNSCC and link oncogenic signaling to glutamine metabolism and mitochondrial function.

This review advances the hypothesis that Traditional Chinese Medicine (TCM) can serve as a formula-defined ecological conditioner within the tumor-immune-soil nexus. We propose a mechanistic blueprint where TCM formulas, rather than acting as nonspecific immunostimulants, function as multi-target systems that re-engineer the tumor microenvironment. The framework integrates three actionable pillars: (1) remodeling the gut microbiome to restore immune-competent consortia and metabolic flux, (2) reprogramming the myeloid compartment away from suppressive M2 macrophages and MDSCs toward immunostimulatory states, and (3) inducing immunogenic cell death to generate critical danger signals. By translating classical concepts like the Gan Pi axis into modern immunometabolism, we propose that TCM can prime the \"soil\" to sensitize MSS mCRC to ICI therapy. However, realizing this potential requires a paradigm shift from descriptive reports to rigorous, biomarker-driven trials. A crucial point is that the nature of a significant portion of existing human evidence remains observational, cross-sectional, or case-control; this limits causal inference and hinders the reconstruction of the long-term temporal sequence extending from the reciprocal dynamics of the immune system and microbiome to cancer progression or treatment response.
