Lessons learned from spatial transcriptomic analyses in clear-cell renal cell carcinoma.

Spatial transcriptomics has emerged as a powerful tool for discerning the heterogeneity of the tumour microenvironment across various cancers, including renal cell carcinoma (RCC). Spatial transcriptomics-based studies conducted in clear-cell RCC (the only RCC subtype studied using this technique to date) have given insights into spatial interactions within this disease. These insights include the role of epithelial-to-mesenchymal transitioning, revealing proximity-dependent interactions between tumour cells, fibroblasts, interleukin-2-expressing macrophages and hyalinized regions.

Colorectal cancer (CRC) is a histologically heterogeneous disease with variable clinical outcome. The role the tumour microenvironment (TME) plays in determining tumour progression is complex and not fully understood. To improve our understanding, it is critical that the TME is studied systematically within clinically annotated patient cohorts with long-term follow-up.

Pain is a signal of inflammation that can have both protective and pathogenic effects. Macrophages, significant components of the immune system, play crucial roles in the occurrence and development of pain, particularly in neuroimmune communication. Macrophages exhibit plasticity and heterogeneity, adopting either pro-inflammatory M1 or anti-inflammatory M2 phenotypes depending on their functional orientation.

Background: Selective corticolimbic vulnerability to tau pathology in Alzheimer’s disease (AD) underlies clinicopathologic heterogeneity. The goal of this presentation will be to examine spatial heterogeneity of tangle distribution on a continuum through the utility of the corticolimbic index (CLix).
Method: We will discuss the development of CLix in the Florida Autopsied Multi‐Ethnic (FLAME) cohort, which sought to collapse the spatial distribution of thioflavin‐S tangle counts in AD (n=1361) to assign a continuum: hippocampal sparing with cortical predominance (<10), representative/typical (≥10 to <30), and limbic predominant with cortical sparing (≥30).
Advances on the Role of Lung Macrophages in the Pathogenesis of Chronic Obstructive Pulmonary Disease in the Era of Single-Cell Genomics.

Chronic Obstructive Pulmonary Disease (COPD) is a heterogeneous respiratory disorder characterized by persistent airflow limitation. The diverse pathogenic mechanisms underlying COPD progression remain incompletely understood. Macrophages, serving as the most representative immune cells in the respiratory tract, constitute the first line of innate immune defense and maintain pulmonary immunological homeostasis.
