Context-dependent regulatory networks connect Alzheimer's disease genetics to microglial inflammatory responses
bioRxiv (Bioinformatics) Published 2026-08-26 Preprint DOI: 10.64898/2026.08.24.746572
computational immunology microglia epigenomics disease genetics
Summary: The study develops context-dependent epigenomic networks from bulk and single-nucleus ATAC-seq across inflammatory, genetic-perturbation, and disease contexts. The framework identifies shared and context-specific regulatory programs, links Alzheimer's disease risk variants to microglial states, and highlights ZBTB14 as a candidate regulator.
Why it matters: It connects genetic variation, regulatory circuits, donor-level cellular states, and inflammatory context instead of treating disease-associated regulation as context-free.
Why for Yiru: The framework is methodologically useful for computational immunology projects that need to interpret how regulatory programs change across perturbations and disease states.
HIDE-Deconv: A hierarchical deconvolution framework for multiscale characterization of cellular remodeling
bioRxiv (Bioinformatics) Published 2026-08-26 Preprint DOI: 10.64898/2026.08.24.746754
deconvolution single-cell omics cellular remodeling multiscale modeling
Summary: HIDE-Deconv jointly estimates cellular compositions across multiple levels of a cell-type hierarchy while enforcing consistency between resolutions. Benchmarking and analyses of lung adenocarcinoma, sepsis, COVID-19, and systemic lupus erythematosus identify remodeling that can remain hidden at broader resolutions.
Why it matters: Hierarchical estimation preserves fine-grained cellular structure while retaining interpretable consistency across resolutions, helping avoid information loss from coarse deconvolution.
Why for Yiru: This is directly transferable to tissue and immune-state analysis where biologically meaningful remodeling may occur within broad cell-type compartments.

Maladaptive immune-fibrotic axis drives impaired long bone regeneration under mechanical instability
Science Advances Published 2026-08-28 Research article DOI: 10.1126/sciadv.adx7511
immunology tissue regeneration spatial transcriptomics mechanobiology
Summary: Using a tunable murine fixation model and spatial transcriptomics, the study shows that high mechanical strain produces fibrotic calluses, persistent fibroblast niches, dysregulated macrophage-fibroblast signaling, and immune signatures associated with impaired fracture healing.
Why it matters: It links mechanical instability to pathological immune-stromal interactions and identifies a measurable biological route from tissue mechanics to failed regeneration.
Why for Yiru: The work is a useful example of combining spatial molecular states with mechanics and immune-cell behavior to explain divergent tissue trajectories.
A spatially resolved implantable microdevice for multiplexed in situ screening of engineered cellular therapies in solid tumors
Science Advances Published 2026-08-28 Research article DOI: 10.1126/sciadv.aee6195
spatial oncology cell therapy CAR-T tumor microenvironment
Summary: An implantable microdevice with independently loaded fibrin reservoirs spatially confines multiple T-cell formulations within live tumors. In glioblastoma xenografts, adjacent regions receiving EGFR-targeting CAR-T cells showed increased CD8+ infiltration, apoptosis, and reduced proliferation relative to control regions.
Why it matters: The device enables parallel, spatially resolved in vivo testing of engineered cell therapies within a shared tumor microenvironment.
Why for Yiru: It offers a practical bridge between spatial tumor biology and multiplexed therapeutic screening, relevant to understanding why cell therapies work in some tumor niches but not others.
Antibody Fc receptor CD16a mediates natural killer cell activation via mechanotransduction of piconewton forces
Science Advances Published 2026-08-28 Research article DOI: 10.1126/sciadv.aeb8946
computational immunology natural killer cells immunotherapy mechanotransduction
Summary: The study shows that CD16a transduces piconewton forces and acts as a mechanosensor during antibody-dependent NK-cell activation. CD16a-associated actin foci and signaling through Cas-L and LAT reshape cytoskeletal dynamics and downstream activation.
Why it matters: It adds a physical-mechanical layer to the biochemical account of Fc-receptor signaling and explains why immobilized, target-bound antibody can activate NK cells differently from soluble Fc multimers.
Why for Yiru: The mechanism is a strong example of how quantitative physical cues can be integrated into models of immune-cell activation and antibody immunotherapy.
Spatial mapping of pediatric brain tumors across diagnoses and relapses
bioRxiv (Cancer Biology) Published 2026-08-26 Preprint DOI: 10.64898/2026.08.25.746606
spatial omics oncology pediatric brain tumors relapse biology
Summary: A spatial transcriptomic atlas of 19 pediatric brain-tumor patients spanning nine diagnoses and seven relapses identifies recurrent spatial archetypes, developmental programs, putative relapse-associated clones, and vascular niches that may support regrowth.
Why it matters: Relapse-spanning spatial maps connect tumor evolution to local tissue niches rather than treating recurrence as a purely genetic or bulk-tissue phenomenon.
Why for Yiru: It is a close fit for spatial oncology and for modeling how cellular neighborhoods and disease trajectories interact across treatment and relapse.

bioRxiv (Cancer Biology) Published 2026-08-26 Preprint DOI: 10.64898/2026.08.25.746926
oncology single-cell omics clinical trajectories tumor microenvironment
Summary: In a multi-scale single-cell dataset from 184 treatment-naive AML patients, the study links clinical outcomes to interactions across genetic alterations, leukemic differentiation, metabolism, immune microenvironment, and residual healthy hematopoiesis.
Why it matters: It frames response and relapse as emergent properties of cross-scale, cross-compartment interactions present at diagnosis.
Why for Yiru: The analysis provides a useful template for integrating molecular state, immune context, and patient trajectory in computational oncology.
