Elastic Energy Storage in Biological Materials: Internal Stresses and Their Functionality

open access: yesAdvanced Materials, EarlyView.
Harnessing and storing internally generated elastic energy is a clever strategy by biological materials to perform functions like shape transformation, movement, and predation. This review explores how biological systems manipulate mechanisms like atomic or protein integration into minerals, protein conformational shifts, phase transitions, and osmotic

Zebrafish Pou5f1‐dependent transcriptional networks in temporal control of early development

open access: yesMolecular Systems Biology, 2010
The transcription factor POU5f1/OCT4 controls pluripotency in mammalian ES cells, but little is known about its functions in the early embryo. We used time‐resolved transcriptome analysis of zebrafish pou5f1 MZspg mutant embryos to identify genes ...

A Programmable Nanovaccine Platform Based on M13 Bacteriophage for Personalized Cancer Vaccine and Therapy

open access: yesAdvanced Materials, EarlyView.
A reprogrammed (RP) phage‐based nanovaccine platform has been developed that allows single‐step assembly with precise control over adjuvanticity, antigen density, and nanoparticle size. By enhancing TLR9 activation and neoantigen display, this platform enables a potent personalized vaccine targeting tumor‐specific neoantigens. When combined with immune

Role of the Mitochondrial Genome During Early Development in Mice [PDF]

open access: yes, 1973
The role of the mitochondrial genome in early development and differentiation was studied in mouse embryos cultured in vitro from the two to four cell stage to the blastocyst (about 100 cells).

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

open access: yesAdvanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

New Perspectives on Semiconducting Conjugated Oligomers for Neuromodulation in Hydra vulgaris

open access: yesAdvanced Materials Interfaces, EarlyView.
Semiconducting organic compounds, thiophene‐based, modify the rhythmic electrical activity of the cnidarian Hydra vulgaris acting on specific neuronal circuits. The ETE‐S trimer also forms electronically conducting wires in the living tissues of the animal.

An Anti‐Myd88 Peptide Synergistically Enhances the Anti‐Inflammatory Effects of Extracellular Vesicles from Naïve Umbilical Cord MSC or HEK293F CD24 Overexpressing Cells

open access: yesAdvanced Materials Interfaces, EarlyView.
This study confirms that extracellular vesicles (EVs) derived from mesenchymal stem cells (MSCs) or HEK293F cells overexpressing CD24 have anti‐inflammatory effects in macrophages and monocytes. Further loading either of these EVs with an anti‐Myd88 peptide synergistically enhanced the anti‐inflammatory effects of the EVs.

Formation and Function of Mammalian Epithelia: Roles for Mechanosensitive PIEZO1 Ion Channels

open access: yesFrontiers in Cell and Developmental Biology, 2019
Mechanical forces play important roles in shaping mammalian development. In the embryo, cells experience force both during the formation of the mammalian body plan and in the ensuing phase of organogenesis.
