CXCL9 (Chemokine (C-X-C motif) ligand 9)

AS601245, AP.24534 and roscovitine were the top three chemotherapeutic agents showing the highest sensitivity differences between the risk groups. The RT-qPCR results indicated that the expression of electron transfer flavoprotein subunit α, rap guanine nucleotide exchange factor-like 1, keratin 7, cluster of differentiation 24, proline rich 15-like, arachidonate 15-lipoxygenase type B, ELOVL fatty acid elongase 2 and C-X-C motif chemokine ligand 9 was consistent with the results of bioinformatic analysis. In conclusion, the HER2-related risk model and nomogram developed in the present study demonstrated high accuracy in predicting patient survival.

Continuous increases in CXCL9 within the cohort strongly associated with greater mortality. CXCL9 is a novel clinical marker that identifies high-risk HLH independent of underlying disease and could be used to select patients for early and aggressive targeted-immunomodulatory therapy.

We analyzed pre- and on-treatment biopsies from patients with HR+ breast cancer treated with letrozole to induce estrogen deprivation (ED)...Finally, deletion combined with silencing of the CXCL11 receptors CXCR3 and CXCR7 in MCF7 cells impaired proliferation in response to exogenous CXCL11 and to co-culture with CD8+ T cells in estrogen-free conditions. These findings suggest that CD8+ T cell-associated CXCL11 in the TIME modulates the response of HR+ breast cancer cells to estrogen suppression.

In conclusion, emapalumab-containing regimens improved or normalized most laboratory parameters in patients with mHLH. Future studies are warranted to establish appropriate emapalumab dosing and utility in this high-risk population.

Targeted interventions showed that decreased expression of Cxcl9 / 10 is responsible for reduced T cell infiltration and weakened anti-tumor immunity. These results show how aged tumor cells are impaired in their recruitment of immune cells, leading to a defective anti-tumor immune response.

CXCL9 + macrophages could play a significant role in inhibiting breast cancer, and their infiltration into tumor tissues is associated with improved survival in breast cancer patients. Immunotherapy targeting CXCL9 + macrophages hold great potential as a therapeutic strategy.

This process promotes the expression of T cell chemokines and upregulates the antigen presentation machinery, thereby enhancing radiation-induced CD8+ T cell antitumor immunity and radiotherapy efficacy. Our findings reveal a critical role of USP5 in type I IFN-induced antitumor immunity, providing potential targets for improving the efficacy of radiotherapy.

IFNG+IL17+CD4+ T cells and CXCL9/10-producing macrophages are key mediators of irColitis. Targeting IL-23 signaling and intestinal macrophages represents a promising strategy to alleviate gut immunopathology without compromising the efficacy of ICB therapy.

The effects of the SNHG26-CDKN2A axis on Cu + ELES(copper plus elesclomol)-induced cuproptosis and CD8+ T cell-mediated anti-tumour immunity were evaluated through cell viability, apoptosis, co-culture cytotoxicity and migration assays...Our findings reveal a novel regulatory axis whereby SNHG26 promotes CRC progression by destabilising CDKN2A mRNA, resulting in enhanced cell proliferation, cuproptosis and immune evasion. This study provides new insights into the molecular mechanisms underlying CRC development.

This study provides insight into unique biomarker profile in patients on ocrelizumab. Increased BAFF was associated with lower IgG and IgA levels, biomarkers of neuroaxonal damage and inflammation in MS patients without recent acute inflammatory activity on ocrelizumab.

R-LNT@LipoC9AP demonstrated superior tumor accumulation, enhanced therapeutic efficacy, and a favorable safety profile. Altogether, the LNT cell-based co-delivery system for CXCL9 and ABEPCSK9 overcomes the limitations of current tumor immunotherapy and may serve as a promising gene therapy strategy for solid tumors treatment.

Compared with existing immune PET tracers that target cytotoxic enzymes, soluble cytokines, or surface activation markers, CXCL9 imaging offers an advantageous balance of specificity, localization, and functional relevance. By visualizing the chemokine gradients that govern T-cell trafficking, CXCL9 PET could serve as an early, noninvasive biomarker of immunotherapy response and a powerful tool for guiding adaptive treatment strategies.
