Infectionwithretroviruses
It is well established with avian retroviruses that cells are most efficiently infected just after they are trypsinized. Trypsinization does two things. First, it apparently exposes the receptor to which the virus binds. Additionally, it stimulates DNA synthesis and cell division, two processes that are essential for the establishment of retroviral infection.Additionally, it is important to do the infection in as sma......阅读全文

噬菌体MOI（multiplicity－of－infection）值及其意义
MOI 是multiplicity of infection的缩写，中文译为感染复数。传统的MOI概念起源于噬菌体感染细菌的研究。其含义是感染时噬菌体与细菌的数量比值，也就是平均每个细菌感染噬菌体的数量。噬菌体的数量单位为pfu。一般认为MOI是一个比值，没有单位，其实其隐含的单位是pfu

PNAS：抗HIV药物或能预防细菌性败血症并发症的发生
细菌感染会导致脓肿（abscesses）形成，即死亡细胞和碎片袋被炎性免疫细胞所包围，细菌会在脓肿中不断繁殖并引起更多验证，进一步损伤周围组织；在严重情况下，这些免疫反应会扩散到全身最终引起危及生命的器官衰竭或败血症发生，但这些脓肿是如何形成的，以及如何预防脓肿发生，此前科学家们并未进行更好地理
