![عکس صفحه اول مقاله: Immune gene expression for diverse haemocytes derived from pacific white shrimp, Litopenaeus vannamei Immune gene expression for diverse haemocytes derived from pacific white shrimp, Litopenaeus vannamei](/preview/png/2431281.png)
• L. vannamei haemocytes were firstly grouped into three different types and the immune related genes expression in grouped haemocytes were estimated.
• ProPO, LGBP and peroxinectin were highly expressed in granular cells.
• LGBP, crustin, lysozyme and P-3a were highly expressed in semigranular cells.
• TGase was highly expressed in hyaline cells.
In this study, diverse haemocytes from Pacific white shrimp Litopenaeus vannamei were spread by flow cytometer sorting system. Using the two commonly flow cytometric parameters FSC and SSC, the haemocytes could be divided into three populations. Microscopy observation of L. vannamei haemocytes in anticoagulant buffer revealed three morphologically distinct cell types designated as granular cell, hyaline cell and semigranular cell. Immune genes, which includes prophenoloxidase (proPO), lipopolysaccharide-β-glucan binding protein (LGBP), peroxinectin, crustin, lysozyme, penaeid-3a and transglutaminase (TGase), expressed from different haemocyte were analysed by quantitative real time PCR (qPCR). Results from the mRNA expression was estimated by relative level of each gene to β-actin gene. Finally, the seven genes could be grouped by their dominant expression sites. ProPO, LGBP and peroxinectin were highly expressed in granular cells, while LGBP, crustin, lysozyme and P-3a were highly expressed in semigranular cells and TGase was highly expressed in hyaline cells. In this study, L. vannamei haemocytes were firstly grouped into three different types and the immune related genes expression in grouped haemocytes were estimated.
