One‐Step Coordinated Multi‐Kinetic 4D Printing of Human Vascularized Cardiac Tissues with Selective Fast‐Shrinking Capillaries

Advanced Materials, EarlyView.
This study presents a novel 4D bioprinting technique for fabricating cardiac tissues with complex microvasculature. Unlike traditional 3D printing, it enables capillary‐scale structure formation via selective post‐printing shrinkage. This approach overcomes resolution limits of printing cell‐laden hydrogels, allowing the creation of functional ...

A Case of Orbital Langerhans Cell Histiocytosis in an Adult

Acta Médica Portuguesa, 2019
Langerhans cell histiocytosis remains an enigmatic disease with a very heterogeneous presentation. We describe a rare case of orbital Langerhans cell histiocytosis in a 39-year-old female patient who presented right orbital pain and edema of the upper ...

Implantable Microarray Patch: Engineering at the Nano and Macro Scale for Sustained Therapeutic Release via Synthetic Biodegradable Polymers

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This review focuses on the application of synthetic biodegradable microarray patches (MAPs) in sustained drug delivery. Compared to conventional MAPs which release drugs into the skin in an immediate manner, these implantable MAPs release drugs into skin microcirculation gradually as the biodegradable polymers degrade, thus offering sustained release ...

Cinobufagin Directly Targets PDE4D to Disrupt Fibroblast–Dendritic Cell Crosstalk in Atopic Dermatitis

Advanced Science, EarlyView.
Single‐cell RNA sequencing revealed that MIF signaling drives inflammatory fibroblastmyeloid cell crosstalk in atopic dermatitis. Cinobufagin, a potent PDE4D inhibitor, suppresses MIF and reduces inflammation by restoring the cAMP/PKA/CREB pathway. Genetic knockout validates PDE4D as a key driver and promising therapeutic target for atopic dermatitis ...

Organoid Modeling of Mouse Anterior Tongue Epithelium Reveals Regional and Cellular Identities

Advanced Science, EarlyView.
The tongue's anterior epithelium is maintained by region‐specific stem/progenitor cells, yet in vitro models are limited. Long‐term expanding organoids are developed from adult mouse anterior tongue that retain region‐specific identity, cellular diversity, and gene regulatory features. These organoids differentiate into keratinocytes, Merkel‐like cells,

Childhood Langerhans cell histiocytosis with severe lung involvement: a nationwide cohort study

Orphanet Journal of Rare Diseases, 2020
Background Lung involvement in childhood Langerhans cell histiocytosis (LCH) is infrequent and rarely life threatening, but occasionally, severe presentations are observed. Methods Among 1482 children (

Single‐Cell Dissection of the Biological Function and Molecular Features Underlying the Micropeptide LSMEM1 in Kidney

Advanced Science, EarlyView.
LSMEM1, an evolutionarily conserved micropeptide with extreme hydrophobicity (aliphatic index═113) and dynamic amphiphilicity (GRAVY═0.017), features a strong α‐helical transmembrane anchor (residues 64‐86). Single‐cell analysis reveals its critical role in renal lipid homeostasis.

Rho-associated kinase regulates Langerhans cell morphology and responsiveness to tissue damage

Cell Reports
Summary: Skin damage requires efficient immune cell responses to restore organ function. Epidermal-resident immune cells known as Langerhans cells use dendritic protrusions to surveil the skin microenvironment, which contains keratinocytes and peripheral

Mechanical Stretch‐Induced Interlayer Coordination between MMP2 and COL17A1 Exacerbates Regenerative Exhaustion in Skin

Advanced Science, EarlyView.
Regeneration reaches a hidden limit under mechanical stretch. Prolonged tension alters dermal–epidermal communication, exhausting epidermal stem cells via MMP2–COL17A1 signaling. MMP2 inhibition by Marimastat preserves adhesion and regenerative capacity, offering a potential strategy to overcome the inherent boundaries of skin expansion.

MiR-23a Regulates Skin Langerhans Cell Phagocytosis and Inflammation-Induced Langerhans Cell Repopulation

Biology, 2023
Langerhans cells (LCs) are skin-resident macrophage that act similarly to dendritic cells for controlling adaptive immunity and immune tolerance in the skin, and they are key players in the development of numerous skin diseases.
