ERVW-1 and viral infectious disease: In an attempt to find other clonal relatives of Ab1485, and in the absence of available LN biopsies at earlier time points after SHIVAD8, we aimed to isolate Env-specific B cells from a PBMC sample collected at week 38 after viral infection using RC1 and BG505 as baits, however, this approach did not yield any B cells to analyze (Figure 1—figure supplement 1F).
