Researchers have identified various distinctive immune cells in cow’s milk, creating potential avenues for enhancing animal health and milk production – as detailed in a study in Animal Nutriomics, published by Cambridge University Press on behalf of Zhejiang University. Using single-cell RNA sequencing to study fresh milk samples, the researchers were able to explore the molecular identities of cow milk in greater detail, particularly immune cells, where they discovered that T cells and granulocytes were present as the main cell types in healthy Holstein cows.
