含有禽网状内皮组织增生病病毒基因组片段的天然重组禽痘病毒的研究

将国内5个不同生产厂家来源的禽痘弱毒疫苗株和1株禽痘野毒株在鸡胚成纤维细胞(CEF)上连续传5代,用禽网状内皮组织增生病病毒(Reticuloendotheliosis virus,REV)特异性的单克隆抗体进行间接免疫荧光试验(Immunonuoreseellee assay,IFA),均检测不到传染性REV。但以6株禽痘病毒(FPV)感染的第2代和第5代细胞基因组提取物为模板,通过PCR均能扩增出REV的长末端重复序列(LTR)和囊膜蛋白(env)基因片段。用特异性核酸探针作分子斑点杂交(Dot blot),结果显示所扩增的PCR条带为特异的REV—LTR和REV—env)基因片段。实验结果表明,国内的一些痘病毒疫苗和野毒株基因组中,已稳定地整合进了REV的基因组成分。

浣熊痘病毒TK基因对5—BUdR药物不敏感性的研究

本文在Ｒａｔ－２（ＴＫ）细胞上，对浣熊痘病毒ＴＫ基因作为病毒筛选 标记的作用进行了研究。发现浣熊痘病毒虽然具有ＴＫ基因的序列和功能，但对５－溴脱氧尿嘧啶（５－ＢＵｄＲ）药物的选择压力并不敏感。即使采用ＨＡＴ培养基挑选的单斑病毒对３－ＢＵｄＲ也具有抵抗力。     

Poxviral immunomodulating proteins: New tools for immunity correction

Many viral proteins are presently known to modulate the protective responses in the host organism. The genomes of Poxviridae have the greatest number of genes coding for proteins that suppress the inflammatory response, action of interferons, immune response, and other protective reactions. This review considers the poxviral immunomodulating proteins: TNF-, chemokine-, and complement-binding proteins and serine protease inhibitors. These proteins demonstrate therapeutic effects in animal models of autoimmune and inflammatory conditions. The applicability of poxviral immunomodulating proteins to treatment of autoimmune and inflammatory disorders in humans is discussed.
