Summary: Breast cancer has different immune subtypes with diverse characteristics and clinical prognostications. Patients with a high immunotherapeutic benefit score (ITBscore) have better response to immunotherapy, while those with a low ITBscore have poor immunotherapeutic efficacy. This study provides insights into the immune phenotypes in the tumor microenvironment and guides precision immuno-oncology and immunotherapy strategies.

Summary: Using single-cell RNA sequencing, researchers found that tuberculosis pleural effusion (TPE) displayed significant differences in cell types compared to other types of effusion (TSPE and MPE), and these differences were associated with disease type. CD4 lymphocytes in TPE favored a Th1 and Th17 response, and immune exhaustion in NK cells was a prominent feature. Myeloid cells in TPE exhibited stronger functional capacity for phagocytosis, antigen presentation, and IFN-γ response. Additionally, macrophages drove the systemic elevation of inflammatory response genes and pro-inflammatory cytokines in TPE patients.

Summary: We identified four immune clusters within paediatric solid tumours, namely Paediatric Inflamed (10%), Myeloid Predominant (30%), Immune Neutral (43%), and Immune Desert (17%). Our findings suggest that personalized immunogenomic profiling is necessary to guide the selection of immunotherapeutic strategies.

Summary: Through studying the molecular and immune characteristics of GGO-associated lung nodules, it was found that compared to solid nodules, GGO-associated lung cancers have a lower tumor mutation burden, less active immune environment, lower T-cell expansion, and less frequent HLA loss of heterozygosity, which may explain their indolent clinical course.

Summary: Recent findings have revealed immune effectors that target nucleotides and the cellular energy currency-free nucleotides. Comparative genomics and sequence-structure analysis have identified several distinct effector domains, which are widely present in prokaryotic immune systems. This study establishes nucleotide-degrading effectors as an emerging immune paradigm and traces their origins back to homologous domains in housekeeping systems.

Summary: This study extracted genetic and epigenetic features of TP53mut tumors and identified five different subtypes of TP53mut patients. These subtypes have distinct characteristics in terms of genomic alterations, clinical relevance, microenvironment dysregulation, and potential therapeutics. Among the subtypes, COCA3 was identified as having the worst prognosis, while olaparib showed promising therapeutic efficacy.

Summary: This study reveals that translational reprogramming plays an important role in rice's response to salt stress, with the salt-tolerant cultivar SR86 adopting a more flexible translational adaptive strategy compared to the salt-sensitive cultivar NB. The differences in translational dynamics under salt stress between NB and SR86 may be due to their varying levels of ribosome stalling.

Summary: Through high-throughput experiments, researchers observed significant variations in binding and cleavage efficacy, as well as specificity, of Cas9 ribonucleoproteins (RNPs) across different guide RNAs. Canonical guide sequences often exhibit unusually high specificity, and the sequence context surrounding the target modulates the Cas9 on-rate. Furthermore, Cas9 RNPs may trap targets in non-productive states that contribute to proofreading capability.

Summary: In this study, the relationship between growth patterns of early-stage lung adenocarcinoma (LUAD) and the tumor immune microenvironment was investigated. The poorly differentiated tumors were found to have a distinct immunogenic tumor microenvironment, which predicts a response to immune agents, including checkpoint inhibitors, in early-stage lung adenocarcinoma. These findings are important for the design of immunotherapy studies in LUAD.

Summary: In the 5th edition of the WHO CNS tumor classification, molecular characteristics have become important diagnostic criteria for many CNS tumor types. This guideline focuses on the methods used for diagnosing gliomas, glioneuronal, and neuronal tumors using informative molecular markers. Various molecular methods are discussed, including next-generation sequencing, methylation profiling, and immunohistochemistry. The guideline also covers the analysis of MGMT promoter methylation status, and provides an overview of the advantages, limitations, and requirements of different assays. The importance of molecular diagnostic testing in neuro-oncology is emphasized, along with discussions on clinical relevance, accessibility, cost, and ethical aspects.

Summary: The authors used T cell profiling in brain tumor samples to understand the biology and therapeutic relevance of the brain tumor microenvironment. They found a tissue-specific conflict between immune suppression and immune activation in brain tumors, which can inform stratification for immunotherapy. Their analysis revealed differences in T cell biology between individuals, with a subgroup of brain metastases showing accumulation of potentially tumor-reactive T cells.

Summary: This study reveals that tumor-associated neutrophils (TANs) in tumor tissues differ significantly from blood neutrophils, and have immune-suppressive and pro-angiogenic capabilities. TANs exhibit distinct inflammatory features in brain metastasis and glioma, and together with tumor-associated myeloid cells, form a critical myeloid niche regulating overall immune suppression in human brain tumors.

Summary: Glioblastoma, a highly malignant brain tumor, exhibits characteristic epigenetic alterations, including the recurrent silencing of the HTATIP2 gene, which affects the nuclear localization of the DNA repair enzyme MPG. The reduced nuclear localization of MPG leads to decreased repair of treatment-induced DNA lesions, contributing to treatment resistance in glioblastoma.

Summary: In this study, the researchers investigated the molecular and cellular mechanisms underlying melanoma cell extravasation across the blood-brain barrier (BBB) to prevent brain metastasis formation. They found that melanoma cells exclusively use the junctional pathway to intercalate into the BBB and that proteases play a crucial role in this process. The compromised BBB barrier properties were shown to facilitate melanoma cell extravasation both in vitro and in vivo. Preserving BBB integrity is an important measure to limit the formation of melanoma-brain metastasis.

Summary: Molecular subtyping of lung squamous cell carcinoma (LUSC) has been performed, but stratification based on tissue metabolomics is lacking. In this study, different tumor and stroma subtypes with distinct metabolite patterns were identified in LUSC patients. The subtypes were associated with specific immunological features and metabolic pathways, and may contribute to personalized therapy.

Summary: The integration of digital pathology (DP) into clinical diagnostic workflows is being emphasized as new hardware and software become available. To facilitate DP adoption, the Swiss Digital Pathology Consortium (SDiPath) organized a Delphi process and generated a series of recommendations for DP integration. Through the collaboration of four working groups, the process produced 83 consensus statements, providing up-to-date resources and best practices to ensure safe and efficient DP usage for national and international hospitals, researchers, and device manufacturers.

Summary: Squamous cell carcinoma (SCC) is a type of lung cancer that can be divided into keratinising, non-keratinising, and basaloid SCC. Histomorphology alone can be used to diagnose keratinising SCC, but immunohistochemical analyses should be used for non-keratinising and basaloid tumors to confirm the diagnosis and exclude other possibilities. In cases where the morphology is ambiguous, a diagnosis of SCC can be made based on squamous immunophenotype. Most SCCs are associated with smoking and have specific molecular characteristics, but there are rare cases in younger and non-smoking patients. Lymphoepithelial carcinoma (LEC) is a poorly differentiated SCC with lymphoplasmacytic infiltrate and often associated with Epstein-Barr virus (EBV). This article describes the morphological and molecular characteristics of SCC and LEC and discusses the important differential diagnoses.
