Cellular and humoral immunity are both important in host defense against severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).Although defects in SARS-CoV-2-specific T cell immunity have been found in patients with severe lung pathology,it is still largely unclear whether virus-specific T cells are sufficient for host ***,we found that in a previously characterized cohort of convalescent subjects,one individual,though lacking detectable anti-viral neutralizing IgG antibodies,showed virus-specific T cell responses,both in CD4^(+)and CD8^(+)T ***-CoV-2-specific T cells in this and other individuals are maintained for up to 10 *** study thus further supports a critical role of T cells in host defense against SARS-CoV-2,offering new insights into the design and evaluation of COVID-19 vaccines.

马铃薯A病毒（PotatovirusA，PVA）是马铃薯生产上危害较严重的病毒之一。PVA已知的寄主为茄科植物，在马铃薯上引起的症状与气候条件、马铃薯品种和PVA的株系有关。PVA基因组与其他PVY属已知序列的病毒核苷酸序列同源性在53％～58％之... 详细信息

马铃薯A病毒（PotatovirusA，PVA）是马铃薯生产上危害较严重的病毒之一。PVA已知的寄主为茄科植物，在马铃薯上引起的症状与气候条件、马铃薯品种和PVA的株系有关。PVA基因组与其他PVY属已知序列的病毒核苷酸序列同源性在53％～58％之间，编码的11种蛋白在基因组复制、蛋白加工、蚜虫传毒、系统移动以及与寄主组分互作等方面具有各自的功能。马铃薯对PVA的抗性分为过敏抗性（HR）和极端抗性（ER）两类，植物对PVA的抗性机制主要分为显性基因介导的抗性、隐性基因介导的抗性、RNA介导的抗性。PVA的致病机理、PVA抗性基因挖掘和抗PVA转基因新策略将是今后的研究重点。
