Figure Lengend Snippet: BNT351 suppresses viremia in HIV-1-infected humanized CD34 + NSG mice without selecting for resistant viral variants (A) Experiment scheme: HIV-1 YU2 -infected CD34 + humanized NSG mice ( n = 7/group) received subcutaneous (SC) injections of BNT351 (1 mg loading dose, followed by 0.5 mg every 3–4 days for 8 weeks) or DPBS (control) on the same days. Plasma viral loads were monitored once weekly for 17 weeks, and plasma SGS was performed at baseline and on day 84, 91, or 98. (B) RT-qPCR was used to measure plasma viral loads. HIV-1 RNA plasma copies (top) and log10 viral load changes compared with baseline (bottom) are shown. Gray shading indicates the BNT351 treatment period. Data points in white indicate viral loads below lower limit of quantification (LLOQ = 774 copies/mL). For visualization in the absolute copy number plots, viral loads
