Spatial proteomics enable detailed analysis of tissue at single cell resolution. However, creating reliable segmentation masks and assigning accurate cell phenotypes to discrete cellular phenotypes can be challenging. We introduce IMmuneCite, a computational framework for comprehensive image pre-processing and single-cell dataset creation, focused on defining complex immune landscapes when using spatial proteomics platforms. We demonstrate that IMmuneCite facilitates the identification of 32 discrete immune cell phenotypes using data from human liver samples while substantially reducing nonbiological cell clusters arising from co-localization of markers for different cell lineages. We established its versatility and ability to accommodate any antibody panel and different species by applying IMmuneCite to data from murine liver tissue. This approach enabled deep characterization of different functional states in each immune compartment, uncovering key features of the immune microenvironment in clinical liver transplantation and murine hepatocellular carcinoma. In conclusion, we demonstrated that IMmuneCite is a user-friendly, integrated computational platform that facilitates investigation of the immune microenvironment across species, while ensuring the creation of an immune focused, spatially resolved single-cell proteomic dataset to provide high fidelity, biologically relevant analyses.

Identifying cell types in highly multiplexed images is essential for understanding tissue spatial organization. Current cell-type annotation methods often rely on extensive reference images and manual adjustments. In this work, we present a tool, the Robust Image-Based Cell Annotator (RIBCA), that enables accurate, automated, unbiased, and fine-grained cell-type annotation for images with a wide range of antibody panels without requiring additional model training or human intervention.

The rapid emergence of mineralized structures in diverse animal groups during the late Ediacaran and early Cambrian periods likely resulted from modifications of pre-adapted biomineralization genes inherited from a common ancestor. As the oldest extant phylum with mineralized structures, sponges are key to understanding animal biomineralization. Yet, the biomineralization process in sponges, particularly in forming spicules, is not well understood.

There is limited understanding of the impact of anti-IL5 treatment on nasal polyp tissue biology in chronic rhinosinusitis with nasal polyps (CRSwNP). This study examined nasal polyp tissue cellular proteome and transcriptome responses to anti-IL5 treatment in CRSwNP utilising spatial profiling. GeoMx™ Digital Spatial Profiling (DSP) of 80 proteins and 1,833 mRNA targets in the polyp stroma and the whole transcriptome (18,815 mRNA targets) in polyp epithelia was undertaken on sinonasal biopsies collected from 20 individuals with eosinophilic CRSwNP before and after 16 and 24 weeks of mepolizumab treatment.

Motivation: Advances in high-throughput technologies have shifted the focus from bulk to single cell or spatial transcriptomic and proteomic analysis of tissues and cell cultures. The resulting increase in gene and/or protein lists leads to the subsequent growth of up- and downregulated pathways lists. This trend creates the need for pathway-network based integration strategies that allow quick exploration of shared and distinct mechanisms across datasets.

Osteoarthritis (OA) is a multifactorial, mechano-inflammatory joint disorder characterized by cartilage degradation, synovial inflammation, and subchondral bone remodeling. Despite its high prevalence and significant impact on quality of life, no disease-modifying treatments have been approved. In many other disease areas, advanced omics technologies are impacting the development of advanced therapies.
