Proteomics data for: Exposure to microplastics reduces attachment strength and alters the haemolymph proteome of blue mussels (Mytilus edulis)
AI summary Read the abstract
This data repository provides haemolymph proteomics data from blue mussels exposed to polyethylene or polylactic acid microplastics for 52 days, supporting a study on how microplastic exposure alters mussel attachment strength and protein expression. The data can be used by other researchers to further analyze microplastic effects on bivalve physiology.
Haemolymph proteomics data from blue mussels (Mytilus edulis) after 52 days of exposure to microplastics made of polyethylene or polylactic acid or to no microplastics (controls).

Exposure to microplastics reduces attachment strength and alters the haemolymph proteome of blue mussels (Mytilus edulis)
AI summary Read the abstract
Researchers found that blue mussels exposed to polyethylene microplastics for 52 days produced fewer attachment threads and lost about 50% of their grip strength. Both conventional and biodegradable microplastics altered proteins in the mussels' blood involved in immune regulation, metabolism, and structural development, suggesting microplastics could undermine reef formation.
First evidence of protein modulation by polystyrene microplastics in a freshwater biological model
AI summary Read the abstract
Zebra mussels were exposed to polystyrene microbeads (1 and 10 μm) for 6 days and analyzed by mass spectrometry-based proteomics, with both particle sizes producing significant changes in protein expression linked to oxidative stress, immune function, and cellular structure. The study provides the first proteomic evidence that microplastics disrupt molecular pathways in a freshwater bivalve model organism.
Quantification and characterization of microplastics in blue mussels (Mytilus edulis): protocol setup and preliminary data on the contamination of the French Atlantic coast
AI summary Read the abstract
Researchers quantified and characterized microplastics in blue mussels from a study site, finding microplastics in a large proportion of sampled individuals and documenting the types and sizes of particles present.
Fragment-Shaped Microplastics Induce Size- and Polymer-Dependent Physiological and Gut Microbial Responses in Mytilus edulis
AI summary Read the abstract
Blue mussels were exposed to fragment-shaped microplastics of different sizes and polymer types in a lab study. Researchers measured how the plastics built up in the mussels and how this affected their physiology and gut bacteria, finding that responses varied depending on microplastic size and polymer type.
Toxicological effects of microplastics in Litopenaeus vannamei as indicated by an integrated microbiome, proteomic and metabolomic approach
AI summary Read the abstract
Shrimp (Litopenaeus vannamei) exposed to five microplastic types for 14 days showed gut microbiota shifts (increased Bacteroidetes and Proteobacteria, decreased Firmicutes) and altered haemolymph proteomes, with each MP type producing distinct immune pathway effects.
