Predicting Axonal Response to Molecular Gradients with a Computational Model of Filopodial Dynamics [PDF]

open access: yes, 2004
Axons are often guided to their targets in the developing nervous system by attractive or repulsive molecular concentration gradients. We propose a computational model for gradient sensing and directed movement of the growth cone mediated by filopodia ...

Engineered Tissue Models to Decode Host–Microbiota Interactions

open access: yesAdvanced Science, EarlyView.
Host–Microbiota interactions in the human body. Created in BioRender. Ghezzi, C. (2025) https://BioRender.com/ihivskg. Abstract A mutualistic co‐evolution exists between the host and its associated microbiota in the human body. Bacteria establish ecological niches in various tissues of the body, locally influencing their physiology and functions, but ...

Molecular mechanisms of Eda‐mediated adaptation to freshwater in threespine stickleback

open access: yesMolecular Ecology, EarlyView., 2023
Abstract A main goal of evolutionary biology is to understand the genetic basis of adaptive evolution. Although the genes that underlie some adaptive phenotypes are now known, the molecular pathways and regulatory mechanisms mediating the phenotypic effects of those genes often remain a black box.

Functional maturation during bovine granulopoiesis [PDF]

open access: yes, 2002
Granulocytic precursor cells undergo morphologic changes in the nucleus and the cytoplasm during the process of granulopoiesis, which takes place in the bone marrow.

Chemokines in the corpus luteum: Implications of leukocyte chemotaxis [PDF]

open access: yesReproductive Biology and Endocrinology, 2003
Chemokines are small molecular weight peptides responsible for adhesion, activation, and recruitment of leukocytes into tissues. Leukocytes are thought to influence follicular atresia, ovulation, and luteal function. Many studies in recent years have focused attention on the characterization of leukocyte populations within the ovary, the importance of ...

Identification of CD38high Monocyte as a Candidate Diagnostic Biomarker and Therapeutic Target for Sepsis

open access: yesAdvanced Science, EarlyView.
This study uncovers that CD38high monocytes discriminate sepsis and sterile inflammation and are associated with 28‐day mortality in bacterial sepsis. Targeting CD38 therapy reduces inflammatory response in monocytes and in sepsis mice model. Mechanistically, CD38‐HIF‐1α/glycolysis/MGO loop exacerbates sepsis‐induced immune dysregulation.

MOF Coating Enhances the Ion Tolerance of Micromotors

open access: yesAngewandte Chemie, EarlyView.
This work reported a novel method to significantly enhance the ion tolerance of EMNMs using a MOF coating via controllable heteroepitaxial growth, enabling effective motion in high‐salt environments and propulsion through biological tissues under 980 nm NIR light, with potential applications in targeted drug delivery.

The Role of MCPIP1 in Macrophage Polarization and Cardiac Function Post‐Myocardial Infarction

open access: yesAdvanced Science, EarlyView.
Following myocardial infarction, MCPIP1 deficiency in macrophages triggers ferroptosis, driving proinflammatory M1 dominance over reparative M2 phenotypes. This imbalance amplifies splenic monocyte release and sustains cardiac inflammation. Concurrently, excessive inflammatory mediators and insufficient TGF‐β impair fibroblast activation, delaying ...

Ladarixin, a dual CXCR1/2 inhibitor, attenuates experimental melanomas harboring different molecular defects by affecting malignant cells and tumor microenvironment. [PDF]

open access: yes, 2017
CXCR1 and CXCR2 chemokine receptors and their ligands (CXCL1/2/3/7/8) play an important role in tumor progression. Tested to date CXCR1/2 antagonists and chemokine-targeted antibodies were reported to affect malignant cells in vitro and in animal models.

Neutrophil Macrophage Crosstalk via Extracellular Vesicles Drives Reverse Migration in a Fully Human Model of Wound Healing

open access: yesAdvanced Science, EarlyView.
A novel microphysiological system that can mimic sterile or non‐sterile injury demonstrates that macrophage‐derived extracellular vesicles modulate neutrophil migratory responses to these different wound states. The model showed that resolution of inflammation through neutrophil reverse migration is driven by IL‐8 derived from extracellular vesicles ...
