Plasma cytokine concentrations in Duffy KO and WT mice following LPS stimulation of whole blood in vitro^a

	Duffy Ag Genotype
Cytokine	KO	WT	p
MIP-2	3728 ± 1605	495 ± 270	0.03
KC	2654 ± 578	1691 ± 346	0.39
TNF-α	132 ± 37	68 ± 42	0.12
CCL2	OOR<	OOR<	NA

^aMIP-2, KC, TNF-α, and CCL2 concentrations in picograms per milliliter and their corresponding SEM are depicted in columns according to genotype. OOR<, Out of range and below the sensitivity of the assay. NA, Not available. Statistical comparisons made between genotypes for each variable cytokine are depicted in the far right-hand column. Data were analyzed by rank sum Mann-Whitney U test and p ≤ 0.05 defined as significant. Data reflects n = 4–6 animals per group and are representative of two independent experiments.
