HIF1A+CSF3R+ neutrophils-dominated hypoxic niche induced metabolic reprogramming for neoadjuvant therapy resistance in NSCLC

Background
Non-small cell lung cancer (NSCLC) is one of the frequently occurring cancers characterized by molecular heterogeneity and multiple immune cell infiltration patterns, which are associated with treatment sensitivity and resistance. However, …

GTPase RAB31 supports ANXA1-driven macrophage education through clathrin-mediated endocytosis to suppress antitumor immunity

Background
Tumor-associated macrophages (TAMs) play pivotal roles in shaping the tumor-microenvironment (TME) through functional plasticity, which is regulated by extrinsic and intrinsic signals. However, the role of vesicular trafficking in TAMs rema…

Ascites reprograms innate lymphoid immune cells in ovarian cancer by promoting ILC2 enrichment and dysfunctional NK-cell states

Background
High-grade serous ovarian cancer (HGSOC) is commonly accompanied by malignant ascites, a clinically relevant tumor niche that promotes immune evasion, metastasis, and treatment resistance. Although natural killer (NK)-cell dysfunction has b…

LARS2 reprograms mitochondrial metabolism and epigenetically upregulates MHC-I to boost antitumor immunity in nasopharyngeal carcinoma

Background
Nasopharyngeal carcinoma (NPC) is considered a typical “hot” tumor, yet its immune evasion mechanisms remain poorly defined, and immunotherapy efficacy is suboptimal. Attenuation of intrinsic tumor cell immunogenicity to evade T cell recogn…

T-cell receptor repertoires against HLA class I-restricted minor histocompatibility antigens are highly diverse with a small subset of public clonotypes

Background
Allogeneic hematopoietic stem cell transplantation (alloHSCT) can be a curative treatment for hematological diseases. After HLA-matched alloHSCT, donor T cells may recognize minor histocompatibility antigens (MiHAs), which are polymorphic H…

T cells are critical for pre-metastatic niche formation through the STAT3/IL-17 axis

Background
Pre-metastatic niches composed of mainly myeloid cells are recognized as critical for tumor metastasis. However, whether adaptive immune cells also play an important role in pre-metastatic niche formation remains to be explored.

Methods
CD…

Turning off methylglyoxal stress: an alternative approach to inhibit MDSC expansion and metastasis in triple-negative breast cancer

Background
Metabolic reprogramming through enhanced glycolysis is a hallmark of cancer that supports tumor progression and promotes protumor immune responses. Methylglyoxal (MG), a reactive by-product of glycolysis, has recently emerged as an oncometa…

Development of an immunocompetent cutaneous squamous cell carcinoma model identifies VISTA and CTLA-4 as targetable immune checkpoints

Background
Immunotherapeutic approaches for cutaneous squamous cell carcinoma (cSCC) remain limited to programmed cell death protein 1 (PD-1) blockade. Although genomics studies have characterized key driver mutations in cSCC, preclinical models that …

PGE2-mediated NK cell reprogramming drives acquired immunotherapy resistance in lung adenocarcinoma

Background
Acquired resistance limits the durability of programmed cell death protein-1 (PD-1) blockade in lung adenocarcinoma, yet the tumor-intrinsic programs and immune circuits that drive acquired resistance relapse remain poorly defined. The purp…

Circulating B cell and T cell activation states predict clinical outcomes in melanoma and reveal dynamic immune reinvigoration with checkpoint inhibitor immunotherapy

Background
Nearly half of patients with melanoma do not respond to immune checkpoint inhibitors (CPIs) and many develop immune-related adverse events (irAEs), often forcing treatment discontinuation, and underscoring the need to predict and monitor ou…
