Splenic MRC1hiMHCIIlocells showed a superior bacterial killing capacity compared to that of MRC1loMHCIIhicells when treated with LPS. A The bar graph represents the remaining bacteria in the FACS-sorted MRC1loMHCIIhi and MRC1hiMHCIIlo cell lysates after 10 (uptake assay) or 60 min (clearance assay) of gentamicin treatment. B The bar graph represents the bacterial killing capacity of MRC1loMHCIIhi and MRC1hiMHCIIlo cells. Data were calculated by subtracting the number of bacteria remaining after clearance from the number from the uptake assay (n = 10). Data are represented as the mean values ± SD. **P < 0.01.
