A New Classification Framework to Understand Evolutionary Transitions in Individuality

BioEssays, Volume 48, Issue 1, January 2026.
Classifying biological entities based on whether and how the two fundamental aspects physiological and evolutionary components are represented yields six types of structural organization. The resulting framework allows to compare different forms of organization, and, in this way, provides insight into the evolutionary processes giving rise to these ...

Structure of the disulfide‐rich modules of a striking tandem repeat protein, avian cysteine‐rich eggshell membrane protein

Protein Science, Volume 35, Issue 1, January 2026.
Abstract Avian eggshell membrane (ESM) is fabricated within the isthmus region of the oviduct and is comprised of three juxtaposed, predominantly proteinaceous layers lying between egg white and the calcified shell. The limiting membrane is less than 0.5 μm in thickness and forms the osmotic barrier for the egg. This first layer provides the foundation

Eine Perspektive zu interdisziplinären Ansätzen in der Chemotaxis(forschung)

Angewandte Chemie, Volume 137, Issue 47, November 17, 2025.
Chemotaxis ist die Bewegung individueller Agenten hin zu oder weg von einem chemischen Stimulus. Dieses Phänomen wird in den verschiedensten Fachbereichen untersucht, von Biologie hin zu Physik und auch im Ingenieurwesen. Dieses Perspektivpapier zielt darauf ab, neue Entwicklungen im Feld darzustellen und die Vereinheitlichung von Terminologie zu ...

Cytokinin Detection during the Dictyostelium discoideum Life Cycle: Profiles Are Dynamic and Affect Cell Growth and Spore Germination

Biomolecules, 2019
Cytokinins (CKs) are a family of evolutionarily conserved growth regulating hormones. While CKs are well-characterized in plant systems, these N6-substituted adenine derivatives are found in a variety of organisms beyond plants, including bacteria, fungi,

Comparative genomics of the social amoebae Dictyostelium discoideum and Dictyostelium purpureum [PDF]

Genome Biology, 2011
Abstract Background The social amoebae (Dictyostelia) are a diverse group of Amoebozoa that achieve multicellularity by aggregation and undergo morphogenesis into fruiting bodies with terminally differentiated spores and stalk cells.

Conserved valproic-acid-induced lipid droplet formation in Dictyostelium and human hepatocytes identifies structurally active compounds

Disease Models & Mechanisms, 2012
SUMMARY Lipid droplet formation and subsequent steatosis (the abnormal retention of lipids within a cell) has been reported to contribute to hepatotoxicity and is an adverse effect of many pharmacological agents including the antiepileptic drug valproic ...

Interactions Between Active Matters and Endogenous Fields

Advanced Materials, Volume 37, Issue 45, November 13, 2025.
This review synthesizes endogenous field information and computational methods in contexts such as cancer, wounds, and biofilms. It organizes NAMs and AAMs by sensing, transmitting, and executing functions, compares their limitations, and from these contrasts proposes design strategies for next‐generation AAMs, offering perspectives to foster ...

Extracellular signaling in Dictyostelium

The International Journal of Developmental Biology, 2019
In the last few decades, we have learned a considerable amount about how eukaryotic cells communicate with each other, and what it is the cells are telling each other. The simplicity of Dictyostelium discoideum, and the wide variety of available tools to study this organism, makes it the equivalent of a hydrogen atom for cell and developmental biology.

Dictyostelium cells migrate similarly on surfaces of varying chemical composition. [PDF]

PLoS ONE, 2014
During cell migration, cell-substrate binding is required for pseudopod anchoring to move the cell forward, yet the interactions with the substrate must be sufficiently weak to allow parts of the cell to de-adhere in a controlled manner during typical ...
