Spatial distribution of TFV, FTC, EFV, and RPV in mouse
spleen.
Distribution profiles of PC (16:0/OH), TFV, FTC, EFV, and EFV–OH
in spleen sections obtained from (A) female and (C) male mice after in vivo dosing of TFV–FTC–EFV. Distribution
profiles of PC (16:0/OH), TFV, FTC, RPV, and RPV–OH in spleen
sections of (B) female and (D) male mice following in vivo oral dosing of TFV–FTC–RPV. Mice were administered
drugs via their drinking water for 28 days and then sacrificed. Spatial
resolution for MALDI MS ion images was 50 μm. The green color
represents the highest signal intensity (100%), whereas the black
color depicts the lowest signal (0%) of the ion of interest. Scale
bar, 1 mm.
