Post‐LECA Origin and Diversification of an Axonemal Outer Arm Dynein Motor
Cytoskeleton, Volume 83, Issue 7, Page 457-465, July 2026.ABSTRACT Dyneins were present in the last eukaryotic common ancestor (LECA) and play key roles in eukaryotic biology. Axonemal dyneins form the inner and outer arms that power ciliary beating, and it has long been recognized that outer arms in some organisms contain two different heavy chain motors, whereas those from other species contain a third unit

Ultrastructure of Naegleria fowleri enflagellation [PDF]
Journal of Bacteriology, 1981 Amoebae of Naegleria fowleri nN68 became elongated flagellated cells 150 to 180 min after subculture to non-nutrient buffer. N. fowleri NF69 did not become elongated or flagellated under these conditions. Electron microscopic examination of N. fowleri confirmed that it is a typical eucaryotic protist with a distinct nuclear envelope and prominent ...

Discovery of an Atypical Arp2/3 Complex in Malaria Parasites Sheds New Light on Nuclear Actin
Cytoskeleton, Volume 83, Issue 7, Page 479-483, July 2026.ABSTRACT The Arp2/3 complex is a key actin nucleator essential for cytoskeletal dynamics in eukaryotes. Previously believed absent in apicomplexan parasites, we recently identified an atypical Arp2/3 complex in malaria parasites consisting of five divergent subunits and a putative kinetochore‐associated factor.

Environmental DNA, Volume 8, Issue 4, July‐August 2026.Comparing 18S metabarcoding of protist cultures and environmental samples with short and long read sequencing highlighted the advantages of each method. In particular, the study of 26 vineyard soil samples with long reads showed high potential and reliability for ecological research with an increased sensitivity to environmental patterns.

Journal of Extracellular Biology, Volume 5, Issue 6, June 2026.ABSTRACT Extracellular vesicles (EVs) are key mediators of intercellular communication, enabling trans‐kingdom exchange of proteins, nucleic acids, lipids, and metabolites. In Giardia duodenalis, EVs contribute to parasite survival, host–pathogen interactions, and immune modulation.
