Splenocyte phenotypes and TNF-α response profiles of mice inoculated with a community microbiota and mice inoculated with a long-stay microbiota in conventional mice (CNV) and germ-free (GF) mice. a Immunostaining of splenocytes. b TNF-α response after splenocyte stimulation with RPMI complete medium as control (RPMI) or with bacterial surface compounds including LPS from Escherichia coli K12 (LPS-Ec), LTA from Staphylococcus aureus (LTA-Sa) or from Bacillus subtilis (LTA-Bs). P values were calculated using the Mann-Whitney U test, *p < 0.05; **p < 0.001
