Chemokinetic and Chemotactic Factors in Psoriasis Scale Extracts

Journal of Investigative Dermatology, 1978
Soluble solutions of psoriasis scale were prepared by extracting scales in 6 m urea and removing urea by dialysis. Extracts were tested for chemokinetic and chemotactic activity for human polymorphonuclear leukocytes and mononuclear cells in vitro using the migration under agarose assay.

Single‐Cell and Spatial Transcriptomic Profiling of Penile Squamous Cell Carcinoma Reveals Dynamics of Tumor Differentiation and Immune Microenvironment

Advanced Science, EarlyView.
This study uses single‐nucleus RNA sequencing and spatial transcriptomics to investigate penile squamous cell carcinoma (PSCC). It reveals that PSCC tumor cells mimic normal penile epithelium differentiation, independent of HPV status. The Tum_1 subtype shows basal stem‐like characteristics and promotes invasiveness. HPV‐positive basal stem‐like tumors

Role of Peptide Backbone Conformation on Biological Activity of Chemotactic Peptides [PDF]

, 1991
To investigate the role of peptide backbone conformation on the biological activity of chemotactic peptides, we synthesized a unique analog of N-formyl-Met-Leu-Phe-OH incorporating the C α,α disubstituted residue, dipropylglycine (Dpg) in place of Leu ...

Modelling cell movement and chemotaxis pseudopod based feedback [PDF]

, 2011
A computational framework is presented for the simulation of eukaryotic cell migration and chemotaxis. An empirical pattern formation model, based on a system of non-linear reaction-diffusion equations, is approximated on an evolving cell boundary using ...

CCN1 Enhances Tumor Immunosuppression through Collagen‐Mediated Chemokine Secretion in Pancreatic Cancer

Advanced Science, EarlyView.
CCN1 modulates the tumor microenvironment in pancreatic cancer by promoting collagen‐dependent chemokine production, thereby facilitating immune evasion. Deletion of CCN1 not only suppresses tumor growth but also enhances immune cell infiltration and increases tumor sensitivity to both chemotherapy and immunotherapy.

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

Advanced 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 ...

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

Advanced 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 ...

A Review of Mathematical Models for the Formation of\ud Vascular Networks [PDF]

, 2012
Mainly two mechanisms are involved in the formation of blood vasculature: vasculogenesis and angiogenesis. The former consists of the formation of a capillary-like network from either a dispersed or a monolayered population of endothelial cells ...

MAGEA6 Engages a YY1‐Dependent Transcription to Dictate Perineural Invasion in Colorectal Cancer

Advanced Science, EarlyView.
This study investigates the role of MAGEA6 in perineural invasion (PNI) in colorectal cancer (CRC). MAGEA6 promotes CRC invasiveness by inhibiting YY1 ubiquitination, enhancing CXCL1 secretion, and recruiting Schwann cells. These findings highlight the potential of targeting the MAGEA6/YY1/CXCL1 axis for therapeutic strategies against PNI and tumor ...

Pro-Inflammatory Chemokines and Cytokines Dominate the Blister Fluid Molecular Signature in Patients with Epidermolysis Bullosa and Affect Leukocyte and Stem Cell Migration. [PDF]

, 2017
Hereditary epidermolysis bullosa (EB) is associated with skin blistering and the development of chronic nonhealing wounds. Although clinical studies have shown that cell-based therapies improve wound healing, the recruitment of therapeutic cells to ...
