Spearman's rank CCs for TLR expression levels within splenic and ileal tissues from C. perfringens-challenged chickens^a

TLR	CC for splenic expression of:					CC for ileal expression of:
	TLR1.1	TLR1.2	TLR2.1	TLR2.2	TLR15	TLR1.1	TLR1.2	TLR2.1	TLR2.2	TLR15
TLR1.2	0.65					0.32
TLR2.1	0.32	0.67				0.29	0.11
TLR2.2	0.42	0.21	0.05			0.55	0.31	0.35
TLR15	0.54	0.71	0.68	0.21		−0.01	0.56	0.21	−0.22
TLR21	0.13	−0.11	−0.06	0.38	−0.04	0.56	0.24	0.43	0.75	−0.05

^aCCs were calculated in a pairwise manner, with high CC values (e.g., approaching 1.00 or −1.00) indicating a high degree of correlation. Positive CC values indicate positive correlation between TLR expression levels, and negative CC values indicate negative correlation between TLR expression levels. Values indicating significant correlations (P < 0.05) are in bold.
