WebDec 12, 2013 · A CRISPR-Cas targeting a specific capsule gene was engineered into nonencapsulated S. pneumoniae and used to infect mice in the presence of heat-killed encapsulated pneumococci . Horizontal transfer of capsule genes from heat-killed cells into live, nonencapsulated bacteria was prevented by CRISPR immunity, resulting in the … WebOct 29, 2024 · SVPs are composed of the HBsAg and host-derived lipids, but do not contain the capsid and the HBV genome. 21 High amounts of SVPs are thought to contribute to generate a state of immune tolerance on both innate and adaptive immunity against HBV. 22 Apart from HBsAg, HBV produces two non-structural proteins, the secreted HBeAg …
