Description of two new species of freshwater leeches of the genus Helobdella (Hirudinea, Glossiphoniidae) from Mexico, with a redescription of Helobdella socimulcensis (Caballero, 1931) [PDF]
ZooKeysFreshwater leeches of the genus Helobdella Blanchard, 1896 (Annelida: Clitellata) are widely distributed in the New World, with most of the species occurring in the neotropics and a single species native to Europe.

Notch signaling in leech neurogenesis: expression patterns and functional insights in the Glossiphoniid leech Helobdella austinensis [PDF]
Animal Cells and SystemsThe Notch signaling pathway is one of the most evolutionarily conserved pathways, playing a crucial role in juxtacrine signaling between adjacent cells.

Head transcriptome profiling of glossiphoniid leech (Helobdella austinensis) reveals clues about proboscis development [PDF]
Open Biology, 2022 Cephalization refers to the evolutionary trend towards the concentration of neural tissues, sensory organs, mouth and associated structures at the front end of bilaterian animals. Comprehensive studies on gene expression related to the anterior formation

First data on the Hirudinea fauna of lotic ecosystems of the Khanty-Mansi Autonomous Area (Russia) [PDF]
ZooKeys, 2022 Hirudinea, a small and ecologically important group of aquatic organisms, is poorly studied in northern Eurasia. In this study, we demyth the idea of the faunistic poverty of this region and present the first findings of rheophilic leeches from the ...

Slit-Robo expression in the leech nervous system: insights into eyespot evolution [PDF]
Cell & Bioscience, 2023 Background Slit and Robo are evolutionarily conserved ligand and receptor proteins, respectively, but the number of slit and robo gene paralogs varies across recent bilaterian genomes.

Intermediate filament genes as differentiation markers in the leech Helobdella [PDF]
Development Genes and Evolution, 2011 The intermediate filament (IF) cytoskeleton is a general feature of differentiated cells. Its molecular components, IF proteins, constitute a large family including the evolutionarily conserved nuclear lamins and the more diverse collection of cytoplasmic intermediate filament (CIF) proteins. In vertebrates, genes encoding CIFs exhibit cell/tissue type-

First record of a potentially introduced leech, Helobdella aff. robusta Shankland, Bissen & Weisblat, 1992 (Hirudinea, Glossiphoniidae), in Japan [PDF]
Check List, 2023 Helobdella aff. robusta Shankland, Bissen & Weisblat, 1992 is recorded for the first time from Japan. The haplotype of the cytochrome c oxidase subunit I (COI) gene sequence of a specimen from Japan is identical to that of one collected in ...
