The Elmo family forms an ancient group of actin-regulating proteins
Communicative & Integrative Biology, 2009 The Elmo protein family members are important mediators of small G protein activity, regulating actin-mediated processes such as chemotaxis and engulfment.

Living on soup:Macropinocytic feeding in amoebae [PDF]
, 2019 Macropinocytosis is used by a variety of amoebae for feeding on liquid medium. The amoebae project cups and ruffles from their plasma membrane, driven by actin polymerization, and eventually fuse these back to the membrane, entrapping droplets of medium ...

mLife, Volume 4, Issue 4, Page 363-377, August 2025.Abstract Aeromonas hydrophila, an opportunistic pathogen, often encodes Type VI Secretion System (T6SS) genes. However, the specific functions of T6SS, particularly in the context of clinical strains, remain poorly understood. In this study, we characterize a multi‐drug‐resistant strain, AH54, which possesses a complete and functional T6SS, composed of

Initiation of multicellular differentiation in Dictyostelium discoideum is regulated by coronin A
Molecular Biology of the Cell, 2014 Multicellular development of Dictyostelium is induced by starvation and is crucial for its long-term survival. Coronin A mediates the transition from growth to development of the cells and initiates the cAMP-dependent relay by regulating the response to ...

Cell migration directionality and speed are independently regulated by RasG and Gβ in Dictyostelium cells in electrotaxis. [PDF]
, 2019 Motile cells manifest increased migration speed and directionality in gradients of stimuli, including chemoattractants, electrical potential and substratum stiffness.

Multiscale modeling of oscillations and spiral waves in Dictyostelium populations
, 2014 Unicellular organisms exhibit elaborate collective behaviors in response to environmental cues. These behaviors are controlled by complex biochemical networks within individual cells and coordinated through cell-to-cell communication.

Fate and regulation of anterior-like cells in Dictyostelium slugs [PDF]
, 1982 A pattern of two tissue types exists in the Dictyostelium slug. Contained within the posterior tissue are anterior-like cells which comprise about 10% of the developing cell mass.

Small Structures, Volume 6, Issue 7, July 2025.Seeded growth onto aggregated seed crystallites of a unimer mixture of polymers containing one crystalline block presents fascinating similarities with the aggregation of Dictyostelium discoideum amoebae into slime molds. The mixture subdivides in two groups to form compartmentalized nanoflowers with thin petals surrounding a thicker central section ...

Spontaneous center formation in Dictyostelium discoideum [PDF]
Scientific Reports, 2019 AbstractDictyostelium discoideum (D.d.) is a widely studied amoeba due to its capabilities of development, survival, and self-organization. During aggregation it produces and relays a chemical signal (cAMP) which shows spirals and target centers. Nevertheless, the natural emergence of these structures is still not well understood.
