WebOct 25, 2024 · Viruses in many untreated patients eventually exhibit a shift in co-receptor tropism from CCR5 usage to either CXCR4 usage or D/M tropism. This shift is temporally associated with a more rapid decline in CD4 counts, 6,7 but whether this tropism shift is a cause or a consequence of progressive immunodeficiency remains undetermined. 1
