Muscling in on Parasitic Flatworms
Parasitology Today, 1998The musculature of parasitic platyhelminths (monogeneans, digeneans and cestodes) presents an attractive target for chemotherapeutic intervention in that it is central to locomotory movement and attachment and serves an essential role in alimentation (feeding, translocation of food and digestive waste) and reproduction (insemination, egg formation and ...

Tetrodotoxins in the flatworm Planocera multitentaculata
Toxicon, 2022The marine polyclad flatworm Planocera multitentaculata is known to possess high levels of tetrodotoxin (TTX), but the presence of TTX analogues in the species has been unexplored. In this study, TTX and several analogues such as 5,6,11-trideoxyTTX, monodeoxyTTXs, dideoxyTTXs, and 11-norTTX-6(S)-ol were identified in three adults and egg plates of P ...

Immunocytochemical localization of histamine in flatworms
Cell and Tissue Research, 1990Specific antibodies against histamine were used to demonstrate the occurrence and cellular distribution of histamine-like immunoreactivity in three species of flatworms (phylum Platyhelminthes). In the parasitic cestode Diphyllobothrium dendriticum, histamine-reactivity was found in neurons of the main nerve cords, and in cells lining the central and ...

A school project to investigate aggregations in flatworms is described. It was found by a series of simple experiments that the formation of aggregations in the flatworm, Polycelis nigra, was influenced by light intensity, temperature, and some form of chemical stimulus released by already aggregating flatworms.

Marine Flatworms provides a fascinating introduction to the intriguing world of polyclad flatworms, a group of large, free-living marine Platyhelminthes, which are found throughout the world but are most colourful in tropical waters. Although not related to molluscs, they are often mistaken for sea slugs because of their brilliant colour patterns.

Development Genes and Evolution, 2011
Wnt genes encode secreted glycoproteins that act in cell-cell signalling to regulate a wide array of developmental processes, ranging from cellular differentiation to axial patterning. Discovery that canonical Wnt/β-catenin signalling is responsible for regulating head/tail specification in planarian regeneration has recently highlighted their ...

Abstract These ‘flatworms’ are bilaterally symmetrical, with marked cephalization, mostly with a mouth, gut, and protonephridia, and typically with hermaphrodite reproductive systems, but without a special body cavity, anus, or circulatory system. Five classes may be recognized.
