Chloroquine (CHL) has been suggested to play an important role in the development of Burkitt's lymphoma by enhancing Epstein-Barr virus expression. Herpes zoster virus incidence is markedly increased following malaria infection in children being treated with CHL. Recently, CHL has also been shown to dramatically increase the transactivation of Tat protein purified from human immunodeficiency virus. These previous studies indirectly suggest that CHL may be involved in the enhancement of virus replication. This study demonstrates for the first time that CHL indeed enhances Semliki Forest virus and encephalomyocarditis virus replication in mice. These results raise the possible connection between the increased spread of AIDS in endemic malaria areas and the wide use of CHL in those areas for the chemotherapy of malaria.
氯喹(CHL)被认为通过增强爱泼斯坦-巴尔病毒的表达在伯基特淋巴瘤的发展中起重要作用。在用CHL治疗的儿童疟疾感染后,带状疱疹病毒的发病率显著增加。最近,CHL还被证明能显著增加从人类免疫缺陷病毒中纯化的Tat蛋白的反式激活。这些先前的研究间接表明CHL可能参与病毒复制的增强。本研究首次证明CHL确实能增强小鼠中塞姆利基森林病毒和脑心肌炎病毒的复制。这些结果提出了在疟疾流行地区艾滋病传播增加与该地区广泛使用CHL进行疟疾化疗之间可能存在的联系。
