Single and repetitive microplastics exposures induce immune system modulation and homeostasis alteration in the edible mussel Mytilus galloprovincialis
Researchers examined transcriptome-wide gene expression changes in Mediterranean mussels after single and repeated microplastic exposures, finding significant immune system modulation and disruption of cellular homeostasis. The study suggests that both short-term and chronic microplastic exposure can alter immune regulation pathways in filter-feeding bivalves, with repeated exposures showing cumulative effects.
Chromosome-Level Genome Assembly of the Blue Mussel Mytilus chilensis Reveals Molecular Signatures Facing the Marine Environment
Scientists assembled the first chromosome-level genome of the Chilean blue mussel, an important aquaculture species in South America. The genome revealed genetic adaptations related to immune defense, stress response, and shell formation that help the mussels survive in challenging marine environments. This genomic resource will support breeding programs and help researchers understand how mussels respond to environmental stressors including pollution.
Molecular mechanisms controlling physiological plasticity in marine mussels under the influence of natural and anthropogenic stress factors
This thesis project investigated the molecular mechanisms that help Mediterranean mussels cope with environmental stress, including both natural factors and emerging pollutants like microplastics.

The gut microbial of sea urchin ( Strongylocentrotus intermedius ) under different temperatures: Microbial structure and co-occurrence patterns
Researchers exposed sea urchins to five temperatures ranging from 13 to 25°C and used high-throughput sequencing to show that elevated temperatures increase gut bacterial diversity, shift dominant genera, alter key metabolic pathways, and strengthen deterministic assembly processes, providing mechanistic insight into how warming reshapes invertebrate gut microbiomes.
Microplastic exposure reshapes the virome and virus–bacteria networks with implications for immune regulation in Mytilus coruscus
Researchers exposed mussels to microplastics for seven days and analyzed how the pollution affected viral communities in their tissues. They found that microplastic exposure suppressed DNA virus diversity while activating RNA viral metabolism, and restructured interactions between bacteria-infecting viruses and opportunistic pathogens. The study suggests that microplastics may influence immune function in shellfish by reshaping the viral community and virus-mediated immune interactions.
Unraveling the interplay between environmental microplastics and salinity stress on Mytilus galloprovincialis larval development: A holistic exploration
Researchers studied how environmental microplastics and increased salinity together affect the early development of Mediterranean mussel larvae. The combination caused larval deformities, developmental problems, and changes in gene activity related to shell formation, stress response, and cell damage. These findings are concerning because climate change is altering ocean salinity in coastal areas where microplastic pollution is also heavy, and mussels are a food source that could pass accumulated microplastics to humans.
