The evolution of the metazoan Toll receptor family and its expression during protostome development
Alcalde, Andrea Orus; Lu, Tsai-Ming; Børve, Aina; Hejnol, Andreas (Journal article; Peer reviewed, 2021)Background: Toll-like receptors (TLRs) play a crucial role in immunity and development. They contain leucine-rich repeat domains, one transmembrane domain, and one Toll/IL-1 receptor domain. TLRs have been classified into ... -
FGF signaling acts on different levels of mesoderm development within Spiralia
Andrikou, Carmen; Hejnol, Andreas (Journal article; Peer reviewed, 2021)FGF signaling is involved in mesoderm induction in members of deuterostomes (e.g. tunicates, hemichordates), but not in flies and nematodes, in which it has a role in mesoderm patterning and migration. However, we need ... -
Marine animal evolutionary developmental biology—Advances through technology development
Stracke, Katharina; Hejnol, Andreas (Journal article; Peer reviewed, 2022)Evolutionary developmental biology, the interdisciplinary effort of illuminating the conserved similarities and differences during animal development across all phylogenetic clades, has gained renewed interest in the past ... -
Molecular and morphological analysis of the developing nemertean brain indicates convergent evolution of complex brains in Spiralia
Gasiorowski, Ludwik; Børve, Aina; Cherneva, Irina A; Orus Alcalde, Andrea; Hejnol, Andreas (Journal article; Peer reviewed, 2021)Background The brain anatomy in the clade Spiralia can vary from simple, commissural brains (e.g., gastrotrichs, rotifers) to rather complex, partitioned structures (e.g., in cephalopods and annelids). How often and in ... -
Morphology of the nervous system of monogonont rotifer Epiphanes senta with a focus on sexual dimorphism between feeding females and dwarf males
Gasiorowski, Ludwik; Furu, Anlaug; Hejnol, Andreas (Peer reviewed; Journal article, 2019-08-07)Background: Monogononta is a large clade of rotifers comprised of diverse morphological forms found in a wide range of ecological habitats. Most monogonont species display cyclical parthenogenesis, where generations of ... -
Peripheral and central employment of acid-sensing ion channels during early bilaterian evolution
Marti Solans, Josep; Børve, Aina; Bump, Paul; Hejnol, Andreas; Lynagh, Timothy Peter (Journal article; Peer reviewed, 2023)Nervous systems are endowed with rapid chemosensation and intercellular signaling by ligand-gated ion channels (LGICs). While a complex, bilaterally symmetrical nervous system is a major innovation of bilaterian animals, ...
