Inhibition of osteosarcoma lung metastases by {beta}-glucan and CD40 agonist is mediated by activation of macrophages and NK cells

Background
Osteosarcoma (OS) lung metastases remain a significant therapeutic challenge. Innate immune activation is a promising therapeutic approach. Innate immune agonists can modulate the tumor immune microenvironment and improve therapeutic respon…

Exceptional tumor-free survival of a patient with metastatic intrahepatic cholangiocarcinoma after surgery and personalized peptide vaccination: revisiting a striking case

Cholangiocarcinomas are rare but aggressive liver tumors of high lethality with scarce treatment options. Here we report on the follow-up of a patient diagnosed with an intrahepatic cholangiocarcinoma who experienced repeated tumor recurrences includi…

Multiomics elucidation of surrounding AT2 cells impeding tertiary lymphoid structures function in neoadjuvant chemoimmunotherapy response of multiple primary lung cancers

The inconsistent immunotherapy response among lesions in patients with multiple primary lung cancer (MPLC) remains poorly understood, presenting a significant challenge for effective treatment. In this study, we conducted a comprehensive multiomics an…

Longitudinal tissue analysis reveals microenvironmental changes correlate with combined immunotherapy and targeted therapy response in metastatic breast cancer

The ability to interrogate changes within the tumor microenvironment (TME) before, during and following therapeutic intervention could yield important understanding of treatment response and causes for disease progression. Yet, the role of investigati…

Hypoxia-induced RCOR2 promotes macrophage M2 polarization and CD8+ T-cell exhaustion by enhancing LIF transcription in hepatocellular carcinoma

Background
The hypoxic microenvironment plays a crucial role in regulating the progression of hepatocellular carcinoma (HCC) and facilitating immune evasion. It is essential to gain a more comprehensive understanding of the pathways through which hypo…

Macrophage NLRP3 activation and IL-1{beta} release drive osimertinib-induced antitumor immunity

Background
Despite the clinical efficacy of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) in non-small cell lung cancer (NSCLC), patient outcomes vary even among those with identical EGFR mutations. This study investigates wh…

O-GlcNAc transferase promotes immune evasion and immunotherapy resistance in uterine corpus endometrial cancer by targeting the glucocorticoid receptor

Background
Although some tumors respond to immune checkpoint blockade therapy, checkpoint inhibitors have been unsuccessful in treating uterine corpus endometrial cancer (UCEC), and the underlying molecular mechanisms remain unclear.

Methods
We inves…

Spatial transcriptomic profiling of metastatic renal cell carcinoma identifies chemokine-driven macrophage and CD8+ T-cell interactions predictive of immunotherapy response

Background
Metastatic renal cell carcinoma (mRCC) still lacks tissue-based biomarkers that predict benefit from first-line immune checkpoint inhibitor (ICI) regimens. High-resolution spatial transcriptomics can dissect the tumor microenvironment (TME)…
