T-tropic才是CXCR4
【Chris】評論
The co-receptor used upon initial infection by HIV is CCR5, which is expressed on myeloid and peripheral, activated, central memory, intestinal, and other subsets of CD4 T cells (macrophages, [M]-tropic virus). Later, during chronic infection of a person, the env gene mutates so that the gp120 binds to a different chemokine receptor (CXCR4), which is expressed primarily on T cells (T-tropic virus)
