Lipidomic insights into the immune response and pearl formation in transplanted pearl oyster Pinctada fucata martensii [PDF]

Frontiers in Immunology, 2022
During pearl culture, the excess immune responses may induce nucleus rejection and death of pearl oysters after transplantation. To better understand the immune response and pearl formation, lipidomic analysis was applied to investigate changes in the ...

Histological and Comparative Transcriptome Analyses Provide Insights Into the Immune Response in Pearl Sac Formation of Hyriopsis cumingii

Frontiers in Marine Science, 2020
Immune response plays an important role in the pearl sac formation and pearl quality. However, there is little knowledge about the mode and mechanism of the immune responses in the pearl sac formation of the pearl mussel Hyriopsis cumingii. In this study,
