Single-Cell RNA Sequencing Profiling Cellular Heterogeneity and Specific Responses of Fish Gills to Microplastics and Nanoplastics
Using advanced single-cell sequencing, researchers mapped how individual cell types in fish gills respond differently to micro- and nanoplastic exposure. Microplastics mainly affected immune cells called macrophages, while nanoplastics primarily targeted T cells, and a structural cell type called fibroblasts was especially sensitive to microplastics. This detailed cell-level view reveals that plastic particles of different sizes can trigger distinct immune and tissue responses.

Nanoplastics: Immune Impact, Detection, and Internalization after Human Blood Exposure by Single‐Cell Mass Cytometry
Using a new single-cell detection method, researchers tracked how nanoplastics interact with 37 different types of human immune cells from blood samples. The nanoplastics were absorbed by and interfered with several immune cell types, particularly monocytes, macrophages, and dendritic cells. Mouse experiments confirmed the nanoplastics accumulated in immune cells in the liver, blood, and spleen, raising concerns about how plastic exposure could disrupt immune function.
Nanoscale Material Size Shapes Distinct Immune Transcriptional States Under Physiological Flow
Scientists exposed human immune cells to tiny plastic particles (nanoplastics) similar to those found in our blood from pollution, and discovered that different sized particles trigger different immune responses. The smaller 40-nanometer particles caused different changes in immune cells compared to larger 200-nanometer particles, and when both sizes were present together, the immune system responded in unexpected ways rather than just adding up the individual effects. This research helps us understand how the growing amount of plastic pollution in our bodies might be affecting our immune systems in complex ways we're just beginning to discover.
Single-cell transcriptomic analysis reveals heterogeneity of the patterns of responsive genes and cell communications in liver cell populations of zebrafish exposed to polystyrene nanoplastics
Researchers used single-cell gene analysis to examine how polystyrene nanoplastics affect different cell types in zebrafish livers. They discovered that various liver cell populations responded to nanoplastic exposure in distinctly different ways, with some cell types showing more disruption to fat metabolism and stress response genes than others. The study reveals that nanoplastic toxicity in the liver is not uniform and that certain cell populations may be more vulnerable than previously understood.
