摘要	T lymphocytes play an important role in cellular and adaptive immunity in vertebrates. The mechanisms of the fish immune system are little studied because of the lack of population-specific antibodies. This study examined the expression of two T lymphocyte markers, TCR alpha (PoTCR alpha) and CD8 alpha (PoCD8 alpha) in the Japanese flounder (Paralichthys olivaceus). The expression of PoTCR alpha and PoCD8 alpha was mainly detected in immune/mucosal tissues. Recombinant PoTCR alpha and PoCD8 alpha were expressed in pET32a and pET259, respectively. Then, rabbit anti-PoTCR alpha serum and rat anti-PoCD8 alpha serum were prepared. Using serum, the characteristics of TCR+ and CD8+ head kidney leucocytes (HKLs) were investigated. The results of laser scanning confocal microscopy (LSCM) demonstrated that TCR alpha and CD8 alpha were transmembrane proteins localized on the cell surface. The populations of CD8 alpha(-), CD8 alpha(+), TCR alpha(-), and TCR alpha(+) were sorted by flow cytometry (FCM) and analysed using qRT-PCR. The results demonstrated that all TCR alpha(+)/TCR alpha(-) or CD8 alpha(+)/CD8 alpha(-) HKLs expressed IFN-gamma. The CD4-1 and IgM transcripts were detected only in TCR alpha(-) and CD8 alpha(-) cells. Furthermore, HKL mitogenesis was induced with concanavalin A (ConA) stimulation. Taken together, the results from LSCM and FCM analyses showed that mammalian and P. olivaceus TCR+ and CD8(+) leucocytes share basic characteristics.
