Knockdown of endogenic pTRIM21 could significantly promote PRRSV replication at 12 and 24 h post infection in iPAMs. Meanwhile, overexpression of pTRIM21 could significantly suppress PRRSV replication but not affect its attachment and endocytosis. Moreover, pTRIM21 RING-finger E3 ubiquitin ligase was essential for anti-PRRSV activity. Our data enhance our understanding of the pTRIMs against PRRSV infection, which may help us develop novel therapeutic tools to control PRRSV.The study assesses what kind of features would allow highly automated vehicles' (HAVs) safe operation in encounters with cyclists and allow avoiding fatal crashes between cyclists and passenger cars. Five features of HAVs' capabilities are formed based on previous studies and evaluated qualitatively using data from fatal crashes between driver-managed passenger cars and cyclist in Finland. By analysing these crashes, it is assessed which features HAVs should have in order to avoid each crash in a hypothetical setting, in which driver-managed cars would be replaced by HAVs. The necessary features of HAVs for crash avoidance are analysed crash-by-crash by considering the obligation to yield, visual obstacles at the crash scene and driver's behaviour prior to the crash. In order to avoid different types of fatal crashes with cyclists, the HAVs should be able to recognize nearby cyclists (feature 1), be aware of the priority rules in various intersections and traffic situations (2), indicate its intentions to cyclists (3), maintain safe driving patterns and anticipate future situations (4), and assess cyclists' intentions (5). Albeit the number of different features to allow crash avoidance is only five, implementing these featu
