Determination of CD-206 and TLR-2 receptors in immune cells in lamina propria of the small intestine of mice given L. casei. Determination of CD-206 and TLR-2 receptors in immune cells in lamina propria of the small intestine of mice given L. casei. (A) Effect of L. casei administration on the number of CD-206+ and TLR-2+ cells. ▪, CD-206+ cells; □, TLR-2+ cells. (B) Microphotography of CD-206+ control cells and cells receiving 7 days of L. casei administration. (C) Microphotography of TLR-2+ control cells and cells receiving 7 days of L. casei administration. Animals received L. casei CRL 431 for 2, 5, or 7 consecutive days. The positive cells were determined on histological sections from the small intestine of the test and control groups by immunofluorescence assays. Values are the means of the results from 3 mice ± SD. *, significant differences between test and control groups (P < 0.001). C. Maldonado Galdeano, and G. Perdigón Clin.
