Figure 5. Summary of the effects of the gut microbiome and L. reuteri on immune cell populations in the blood, spleen, MLN, and PP. (A) Differences in immune cell populations in GF mice relative to CONV mice; (B-E) Differences in immune cell populations in (B) CONV mice; (C) mice conventionalized at four weeks of age (DC mice); (D) L. reuteri R2lc treated mice (R2lc mice); and (E) L. reuteri PB-W1 treated mice (PB-W1 mice) relative to mice conventionalized soon after birth (EC mice). Horizontal double-headed arrows indicate no difference between the groups, upward arrows represent a relatively greater amount, and downward arrows represent a relatively lesser amount.
