High levels of plastic pollution can kill the embryos of a wide range of ocean animals, new research shows.
Scientists tested the effects of new PVC pellets (pre-production “nurdles” used to make many plastic products) on the development of ten species, spanning all major groups (superphyla) of ocean animals.
Exposure to high concentrations of PVC pellets prevented healthy development in all ten species.
The main process affected was morphogenesis – an organism developing its shape – and shapeless embryos cannot survive.
The study, by an international team led by the Stazione Zoologica Anton Dohrn (Italy) and in collaboration with the University of Exeter (UK), the University of Barcelona (Spain) and Queen Mary University of London (UK), highlights the “potentially catastrophic effects” of rising levels of plastic in the ocean.
“When exposed to high levels of new PVC pellets, the species we examined went wrong in different ways,” said first author Dr Eva Jimenez-Guri.
“Some failed to make a shell or a notocord, some failed to form proper bilateral (left-right) features, some just stopped developing after a few rounds of cell division.
“They all failed to make a viable embryo.”
The study also included species that reproduce asexually by regeneration (splitting) and found these were also affected by high concentrations of new PVC pellets.
“The level of pollution we examined would only be seen in circumstances such as a spill of PVC pellets,” Dr Jimenez-Guri said.
“We know these happen. For example, millions of pellets were spilled from a cargo ship off Portugal in January.
“Rivers and beaches near petrochemical plants have also been found to contain these very high levels of pre-production pellets.”
The European Union is currently debating legislation aimed to reduce releases of pre-production plastic pellets.
The study also examined the toxic effects of plastic samples recovered from beaches.
While the effects were not as widespread as those of new PVC pellets, high concentrations were found to affect the development of molluscs, sea urchins, sea stars and sea squirts.
Coasts and rivers are known hotspots for plastic pollution and – as the species in the study all live in coastal areas – severe pollution could have a major impact.
“If you have extreme pollution at a time when these species are reproducing, then you don’t have the next generation of those species,” Dr Jimenez-Guri said.
Explaining how plastics cause developmental abnormalities, Dr Jimenez-Guri said plastics contain a complex variety of potentially harmful components including zinc in this case – which are slowly released once plastic is in the water.
The research was funded by a Marie Skłodowska-Curie Action Fellowship awarded to Dr Jimenez-Guri.
The paper, published in the journal Chemosphere, is entitled: “Developmental toxicity of pre-production plastic pellets affects a large swathe of invertebrate taxa.” (https://www.sciencedirect.com/science/article/abs/pii/S004565352400780X)

The research team led by Dr. Maria Ina Arnone at Stazione Zoologica Anton Dohrn published a new paper describing the development and characterization of the cells producing the Thyrotropin-releasing hormone (TRH) from early developmental stages to post-metamorphosis juvenile stage.
Sea urchins have a complex development, the embryonic stages are followed by the larva stage, called pluteus. The larva does not resemble the adult, which is produced by metamorphosis. Throughout development, the nervous system becomes more and more complex. Using techniques to visualize mRNAs and proteins, it is possible to identify specific neurons, obtain information on their function and follow their changes over the course of development.
In this study, the research team focused their attention on a specific group of neurons (called TRHergic cells) which produce a homolog of the TRH, a hormone found in the brain controlling thyroid function in mammals. In particular, the researchers identified the TRHergic cells at different developmental stages in the Mediterranean sea urchin species Paracentrotus lividus showing how the number of cells and axons increases and eventually form an extensive net of TRHergic neurons. Such net colonizes almost all juvenile’s structures, including spines and tube feet.
Finally, the researchers identified other genes expressed by the TRHergic cells in the P. lividus and compared these cells with the TRHergic cells in other sea urchins: Strongylocentrotus purpuratus, Arbacia lixula and Heliocidaris tuberculata; thus they investigated how these neurons evolved.

The paper has been published in Frontiers in Neuroscience
(https://www.frontiersin.org/journals/neuroscience/articles/10.3389/fnins.2024.1378520/full), and it was performed in Dr. Arnone’s laboratory at Stazione Zoologica Anton Dohrn by Dr. Maria Cocurullo in collaboration with Dr. Periklis Paganos and Dr. Giovanna Benvenuto.

In 1898, Camillo Golgi described the intracellular structure that later took his name, the Golgi apparatus, which we now know to be involved in the transport and modification of proteins destined for secretion. The Golgi apparatus can be formed by single or multiple units; the latter can remain independent or connect to each other in a centralized structure called the Golgi 'ribbon'. The ribbon is generally considered an organization of the Golgi apparatus exclusively present in the cells of vertebrate animals. The reason why the Golgi ribbon has evolved, and its biological functions are not clear. However, in various pathologies, including neurodegenerative diseases, this organization of the Golgi apparatus is lost, indicating its importance for cellular physiology.
Working on cellular secretion, first at UConn Health in the United States and later at University College London in the United Kingdom, Dr. Ferraro has long been fascinated by the Golgi ribbon, hypothesizing that its functions can be deciphered through a comparative biology approach, from an evolutionary perspective. Back in Italy, at the Anton Dorhn Zoological Station, Dr. Ferraro focused his interests on the Golgi ribbon, conducting a study involving numerous colleagues from the Neapolitan institute and research centers in France, Spain, Germany, the United Kingdom, Norway, and the United States (*). The study, recently published in the journal Cell Reports, discovered that far from being exclusive to vertebrates, the Golgi ribbon is present in the cells of many taxonomic groups of animals. These observations indicate that this structure of the Golgi apparatus appeared early in the evolutionary history of animals, before their diversification into the groups existing today. The study also revealed that this structure, initially absent, forms during embryonic development in the sea urchin, ascidian, and amphioxus. This observation suggests the possibility that the Golgi ribbon has a function in embryonic development and that perhaps this is the ancestral role for which it evolved.
By revealing the unexpected and widespread presence of the Golgi ribbon among animals, the study, which relied on interdisciplinary collaboration of zoologists, cellular biologists, evolutionary biologists, and developmental biologists, brings the attention of the scientific community to this enigmatic structure and the importance of deciphering its functions. Future studies in this direction will allow for a better understanding of the role of the Golgi ribbon in the evolution of animal cells and in their physiology, and the consequences of its loss on the course of neurodegenerative diseases and other pathologies.

A morphological investigation of the Golgi apparatus in present-day species allowed the identification of the origin of the Golgi ribbon during the evolutionary history of animals in the common ancestor of cnidarians (jellyfish and corals) and bilaterians (all animals with bilateral symmetry).

The images show a sea urchin embryo (Paracentrotus lividus) labeled with fluorescent reporters of the Golgi apparatus (green) and the plasma membrane (magenta). It can be observed how the Golgi apparatus, initially present as separate elements in embryonic cells, becomes a single structure, the Golgi ribbon. Times elapsed since fertilization are indicated.
