We describe a paradigm wherein combined high TLS and low tissue-resident exhausted CD8+ T cells are required for optimal response to PD-1 blockade in RCC. This analysis identifies key determinants of response to PD-1 blockade in advanced RCC and suggests avenues for future immune modulation through rational combination therapy strategies.

Pancreatic ductal adenocarcinoma (PDA) is defined by a myeloid-enriched microenvironment and has shown remarkable resistance to immune checkpoint blockade (e.g., PD-1 and CTLA-4).

Hepatocellular carcinoma (HCC) is a highly aggressive malignancy, largely driven by an immunosuppressive tumor microenvironment (TME) that facilitates tumor growth, immune escape, and resistance to therapy. Although immunotherapy-particularly immune checkpoint inhibitors (ICIs)-has transformed the therapeutic landscape by restoring T cell-mediated anti-tumor responses, their clinical benefit as monotherapy remains suboptimal. This limitation is primarily attributed to immunosuppressive components within the TME, including tumor-associated macrophages, regulatory T cells (Tregs), and myeloid-derived suppressor cells (MDSCs).

Clear cell renal cell carcinoma (ccRCC) is a neoplastic disease associated with poor prognosis. Localized disease is successfully treated with nephrectomy; however, advanced disease often requires the combined use of immunotherapy and targeted therapy. To the best of our knowledge, there is no validated method to predict immunotherapy response and there is a lack of knowledge regarding the expression kinetics of exhaustion receptors in the early stages of ccRCC.

Background: Epigenetic regulation significantly affects immune responses in lung adenocarcinoma (LUAD). However, the role of RNA N6-methyladenosine (m6A) modification, especially in obstructive sleep apnea-hypopnea syndrome (OSAHS) within LUAD, is not well understood.
Methods: This study examined m6A modification patterns in 973 LUAD patients using 23 regulatory genes.

HIV-associated lymphoma (HAL) is an aggressive malignancy directly linked to HIV infection and accounts for more than 30% of cancer-related deaths in people living with HIV (PLWH). HAL subtypes, including diffuse large B-cell lymphoma (DLBCL), Burkitt lymphoma (BL), primary effusion lymphoma (PEL), and plasmablastic lymphoma (PBL), exhibit five to ten times higher incidence rates and distinct molecular profiles compared to HIV-negative lympho-mas. Pathogenesis involves HIV-driven CD4+ T-cell depletion, chronic B-cell activation, and on-cogenic viral coinfection.
