WebHost strategies for combating infection can be grouped into two categories: host tolerance and host resistance (Boots et al. 2009). Host tolerance describes the ability of a host to tolerate ... WebThe first article by Long et. al. 1 focuses on Atlastin proteins (ATLs), large dynamin-related GTPases that regulate ER membrane function, and their role in promoting KSHV lytic activation and infection. Overexpression of ATLs enhances lytic infection while deletion has the opposite effect. This response is also correlated with induction of ER stress and that …
