Background
Major histocompatibility complex class I (MHC)-I loss is a prevalent mechanism for immune evasion and resistance to immunotherapy. However, how MHC-I loss shapes the tumor microenvironment and influences immune cell interactions, ultimately…
Background
Perineural invasion (PNI) is a hallmark of malignancy in solid tumors, including oral squamous cell carcinoma (OSCC), and is closely associated with poor prognosis. Emerging evidence suggests a critical association between PNI and the tumor…
Background
The contribution of B cells to antitumor immunity remains controversial, with studies reporting varied effects across cancer types. Even less is known about the role of the endogenous humoral response, including when tumor-elicited antibodi…
Background
Neoantigen-specific tumor-infiltrating lymphocytes (TILs) have the ability to mediate responses in patients with metastatic epithelial cancers. While some identified factors are associated with response, there is a need for ways to determin…
Background
Although HER2-targeted therapies have dramatically improved outcomes for patients with HER2-positive breast cancer, the immunosuppressive tumor microenvironment remains a major barrier to effective immunotherapy in this subtype. Therefore, …
Background
Neoadjuvant immune checkpoint blockade (ICB) combined with chemotherapy has demonstrated higher response rates than chemotherapy alone in resectable esophageal squamous cell carcinoma (ESCC). Although tumor microenvironment (TME) features a…
Background
Small cell lung cancer (SCLC) is a recalcitrant malignancy with limited responses to immunotherapy, largely due to its uniquely immunosuppressive tumor microenvironment (TME). However, the molecular mechanisms driving this phenotype remain …
Background
Humanized mice are highly valuable models for the preclinical development of cancer immunotherapies. However, conventional models often fail to mount robust and trackable tumor antigen-specific (TA-specific) T-cell responses, which hinders …
Background
Tumor-associated macrophages are pivotal drivers of hepatocellular carcinoma (HCC) progression. However, the functional contributions of proliferating macrophages (Prolif Ms) within the tumor microenvironment (TME) remain poorly defined.
M…
Background
Antigen-specific CD8+ T cells can be in a stem-like programmed cell death protein-1 (PD-1)+TCF-1+ differentiation state that progresses into terminal exhaustion in cancer and chronic infection. These stem-like cells are important, since the…
