Spatial proteomics of hippocampal subfield-specific pathology in Alzheimer’s disease and primary age-related tauopathy
INTRODUCTION: Alzheimer's disease (AD) and primary age-related tauopathy (PART) both harbor 3R/4R hyperphosphorylated-tau (p-tau)-positive neurofibrillary tangles (NFTs) but differ in the spatial p-tau development in the hippocampus. METHODS: Using Nanostring…

Peritumoral immune suppressive mechanisms impede intratumoral lymphocyte infiltration into CRC liver versus lung metastases
Microsatellite stable (MSS) colorectal cancer (CRC) patients with liver metastases are resistant to immune checkpoint inhibitor (ICI) therapy, while about one-third of CRC patients without liver metastases, particularly those with…

Digital spatial profiling of melanoma shows CD95 expression in immune cells is associated with resistance to immunotherapy
Although immune checkpoint inhibitor (ICI) therapy has dramatically improved outcome for metastatic melanoma patients, many patients do not benefit. Since adverse events may be severe, biomarkers for resistance would be…

Molecular portraits of patients with intrahepatic cholangiocarcinoma who diverge as rapid progressors or long survivors on chemotherapy
Objective: Cytotoxic agents are the cornerstone of treatment for patients with advanced intrahepatic cholangiocarcinoma (iCCA), despite heterogeneous benefit. We hypothesised that the pretreatment molecular profiles of diagnostic biopsies can predict…

Upregulation of Indoleamine 2,3-dioxygenase 1 in tumor cells and tertiary lymphoid structures is a hallmark of inflamed non-small cell lung cancer
Purpose: Overexpression of the tryptophan-catabolizing enzyme indoleamine 2,3-dioxygenase 1 (IDO1) has been reported in several tumor types, including NSCLC, and has been shown to promote tumor immune evasion and inhibit…

Characterization of mismatch-repair (MMR)/microsatellite instability (MSI)-discordant endometrial cancers
Background: Mismatch-repair (MMR)/microsatellite instability (MSI) status has therapeutic implications in endometrial cancer (EC). The authors evaluated the concordance of testing and factors contributing to MMR expression heterogeneity. Methods: Six hundred…

Exposure to environmental airborne particulate matter caused wide-ranged transcriptional changes and accelerated Alzheimer’s-related pathology: A mouse study
Air pollution poses a significant threat to human health, though a clear understanding of its mechanism remains elusive. In this study, we sought to better understand the effects of various…

Method for high-plex analysis of immune cells in human skin using the GeoMx system
Specific T cell populations in the skin have been demonstrated as important disease drivers in several dermatoses. Due to the unique skin architecture, these cells are not grouped together in…

Exercise Training Reduces the Inflammatory Response and Promotes Intestinal Mucosa-associated Immunity in Lynch Syndrome
Purpose: Lynch Syndrome (LS) is a hereditary condition with a high lifetime risk of colorectal and endometrial cancers. Exercise is a non-pharmacological intervention to reduce cancer risk, though its impact…

Spatial Decoding of Immune Cell Contribution to Fibroblastic Foci in Idiopathic Pulmonary Fibrosis
Idiopathic pulmonary fibrosis (IPF) is characterized by heterogeneity, manifested as patchy lesions evident in histopathologic and radiologic findings of the lung (1). Although current technologies, such as single-cell sequencing and…

Enhanced antitumour immunity following neoadjuvant chemoradiotherapy mediates a favourable prognosis in women with resected pancreatic cancer
Background: This study investigates sex disparities in clinical outcomes and tumour immune profiles in patients with pancreatic ductal adenocarcinoma (PDAC) who underwent upfront resection or resection preceded by gemcitabine-based neoadjuvant…

Spatial Transcriptomics Reveals Distinct Tissue Niches Linked with Steroid Responsiveness in Acute Gastrointestinal GVHD
Severe acute graft-versus-host disease (aGVHD) is associated with significant mortality and morbidity, especially in steroid-resistant (SR) cases. Spatial transcriptomic technology can elucidate tissue-based interactions in vivo and possibly identify predictors…
