ATP7A and infection: (Ladomersky et al., 2017) They then detected the copper level in Atp7aLysMcre cells and measured the susceptibility of CopA and GolT knockout S. Typhimurium in the liver and spleen of Atp7aLysMcre mice and controls, concluding that bacterial ATPases CopA maintain phagosome copper levels and GolT is required for S. Typhimurium invasion, while ATP7A-dependent copper trafficking to phagosome controls the infection.
