Expression of chemokine receptors by murine CD4⁺ LPLs. Murine CD4⁺ small intestinal LPLs were stained with antibodies to (A) CD69 and CD62L or (B) CD62L and a pool of chemokine receptors (CCR2, CCR5, CCR6, CCR8, CCR9, CCR10, CXCR3, CXCR6). Numbers represent percentage of CD4⁺ LPLs in each quadrant and are from one representative experiment of 2 to 4 performed. (C) CD4⁺ CD69⁺ LPLs were stained with antichemokine receptor (blank) or isotype control antibody (shaded). Representative plots from one representative experiment of 3 to 6 performed. Numbers are the mean (SEM) from 3 to 6 experiments using pooled cells from 3 to 10 mice/experiment except CCR5 (1-4 mice/experiment). (D) CD4⁺ LPLs were stained with antibodies to 2 chemokine receptors. Results are from 1 representative experiment of 3 to 4 using pooled cells from 4 to 10 mice/experiment.
