Toll-like receptor gene expression in day 1 foal, day 42 foal, and adult horse samples.

Expression (quantified by number of reads on y-axis) of TLR genes in day 1 foal (circle), day 42 foal (square), and adult (triangle) samples are plotted on the x-axis. The significance level of comparisons is indicated by asterisks (* p<0.05; ** p≤0.001; *** p≤0.0001); comparisons that did not differ statistically are labeled “NS” to denote not significant.
