Although CCL4 and CCL5 expression was higher in livers of infected WSX-1−/− mice than infected WT mice, and hepatic CD4+ T cells from WSX-1−/− mice expressed higher levels of CCR5 than cells from WT mice, migration of CD4+ T cells to the liver of WSX-1−/− mice during infection was not controlled by chemokine (R) signalling. Here, CCR5 is linked to infection.
