Kidney innate immune response at birth and postnatal day 5 following IA LPS exposure. (A,B) MPO+ stained cells (brown) in the frozen kidney, (C–G) mRNA levels of toll-like receptors (TLR2 and TLR4) and neutrophil/macrophage components (LTF, S100A9, and LYZ) in kidney tissues. Data are presented as mean ± SEM. *p < 0.05 and **p < 0.01. Day 1: both n = 9, Day 5: n = 8 in control and 9 in LPS. The scale bars in (A) represent 100 μm. LTF, lactoferrin; TLR, toll-like receptor; and LYZ, lysozyme.
