Advances in identification and application of tumor antigen inducing anti-cancer responses

Tumor antigen is one of the important bases of tumor immunotherapy . With the discovery of novel tumor antigens, interest in specific immunotherapy for treatment of malignancies has increased substantially. Nowadays more and more scientists paid close attention to various tumor antigens with their roles or/and applications in anti-cancer immune responses, immune tolerance, tumor markers,     

N-terminal of L protein of vesicular stomatitis virus contains a new signal sequence

The L protein (241kD) of vesicular stomatitis virus (VSV) is the most important snbnnit of the replication complex. The existence of specific localization signal in the L protein was investigated by making recombinant constructs expressing truncated mutants of the L protein fused to green fluorescent protein (GFP) in transient transfection assays. The chimeric genes encoding varied N-terminal of L and GFP gene were put under the control of T7 promoter or CMV promoter. The fusion proteins were transiently expressed in BHK-21, COS-7, CHO or Hep G2 cells. When more than 120 residues were deleted or only 96 residues were kept on the N-terminal, the fusion proteins were shown to be distributed throughout the cells, cytoplasm and nucleus under the confocal microscope. However, other chimeric proteins with 120 or more amino acids were dotted and distributed in the perinuclear regions. And the fusion protein with 96—120 aa has the similar distribution. A thirteen-residue peptide QGYSFLHEVDKEA (108—120) was identified as localization signal, whose function would be absolutely distributed with the deficiency of D or V. Our results show that there is an independent localizing signal in N-terminal domain of L protein of VSV and this functional signal is conserved in different cell lines.

基于核壳荧光纳米颗粒的一种新型纳米pH传感器

改进了一种基于新型的荧光染料——二氧化硅的核壳荧光纳米颗粒的纳米pH传感器，以异硫氰酸荧光素(FITC)标记的羊抗人免疫球蛋白IgG为核材料，采用实验条件简单的油包水的微乳液方法制备荧光纳米颗粒，该方法有效地防止了荧光染料在二氧化硅壳层中的泄露。这种FITC的核壳荧光纳米颗粒对pH敏感，在pH值5．5—7之间呈线性响应，且能被单个小鼠巨噬细胞吞噬，借此用于单细胞中pH的实时监测。
