Objective To construct an eukaryotic expression vector for TAP genes fused with enhanced green fluorescent protein(EGFP)gene,and to analyze the expression and subcellular localization of the fusion protein in A375 human malignant melanoma cells transfected with the eukaryotic expression vector.Methods A375 cells were cotransfected with the combination of plasmid(P)TAP1-EGFP or pTAP2-EGFP and pDsRed2-endoplasmic reticulum(ER),or with pEGFP-TAP1 and-TAP2,or monotransfected with pTAP1-EGFP or pTAP2-EGFP alone.The monoclonal A375 cells stably expressing TAP were obtained by G418 selection.Then.the distribution and expression of fusion proteins were assessed in A375 cells by using fluorescence microscopy and Western blot,respectively.Flow cytometry was used to measure the expression of HLA class Ⅰ on A375 cells.Results Transfection of A375 cells with pTAP1-EGFP or pTAP1-EGFP and pTAP2-EGFP significantly increased the expression of TAP 1 and TAP 2 in as well as HLA class Ⅰ antigen on A375 cells.The green fluorescence of TAP1-EGFP and TAP2-EGFP overlapped with the red fluorescence of ER marker in cotransfected cells.indicating that TAP was localized subcellularly on the ER.Conclusions The expression vector for TAP-EGFP fusion gene has been constructed cuccessfully and expressed in A375 cells,and the expressed fusion protein is subcelluiarly localized to ER.This study will provide a basis for the research into subsequent immune response following induction of TAP expression.

Objective To explore the expression of transporter associated with antigen processing (TAP) and major histocompatibility complex class (MHC)-Ⅰ molecule in malignant melanoma cell lines. Methods Three malignant melanoma cell lines, including A375, A875, and KZ28 cells as well as normal melanocytes were cultured. Western blot, reverse transcription PCR and flow cytometry were used to detect the protein and mRNA expression of TAP as well as the membrane expression of MHC-Ⅰ in these cells. Results A significant decrease was observed in the expression of TAP mRNA (t = 5.89, 4.45 and 4.57 re-spectively, all P< 0.01) and protein (t= 5.46, 4.32 and 4.67 respectively, all P< 0.01) in A375, A875 and KZ28 cells compared with the melanocytes, with the strongest decrease occurring in A375 cells. Similarly, the expression of MHC-Ⅰ molecule was significantly lower in A375, A875 and KZ28 cells than that in the melanocytes (t= 6.16, 5.22 and 5.61 respectively, all P< 0.01).Conclusions The protein and mRNA expres-sion of TAP is down-regulated in three melanoma cell lines A375, A875 and AZ28, which may contribute to the escape of melanoma cells from human immune surveillance.

Objective To investigate the expression and distribution of cellular FLICE-inhibitory protein (c-FLIP) in peripheral blood and lesions of psoriatic patients. Methods Peripheral blood and skin samples were obtained from 30 patients with psoriasis vulgaris and 20 normal controls. Flow cytometry was used to detect intracellular c-FLIP protein in peripheral T and B lymphocytes, immunohistochemistry to examine the expression of c-FLIP in lesional tissue. Results Based on the positivity rate of c-FLIP, there was a significant increase in T lymphocytes in active psoriasis compared with regressive psoriasis and normal controls (6.32%±1.17% vs 2.64%±0.74% and 2.28%±0.54%, P＜0.01 and 0.05, respectively), while no significant difference was found in B lymphocytes among these three groups (0.78%±0.16%, 0.71%±0.32%, 0.69%±0.18%, respectively, P＞0.05). The expression intensity of c-FLIP in keratinocytes was also higher in active psoriasis than in regressive psoriasis and normal controls (89.73±5.24 vs 117.40±7.50,121.58±7.93, P＜0.01 and 0.05 respectively), and there was no difference between regressive psoriasis and normal controls (P＞0.05). Conclusions c-FLIP is highly expressed in lesions and peripheral T lymphocytes of patients with active psoriasis, suggesting the possible involvement of c-FLIP in the proliferation of T lymphocytes in psoriasis.
