FIG. 3.

(A and B) Numbers of LALN CD4⁺ (A) and CD8⁺ (B) lymphocytes recovered at serial time points after M. tuberculosis infection in the LED and LCD groups. There are no differences between the groups at any time point for LALN CD4⁺ or CD8⁺ lymphocytes. (C and D) Numbers of lung CD4⁺ (C) and CD8⁺ (D) lymphocytes recovered at serial time points after M. tuberculosis infection in the LED and LCD groups. There are significantly fewer lung CD4⁺ lymphocytes in the LED group than in the LCD group at days 21 and 28 and fewer lung CD8⁺ lymphocytes at days 14, 21, and 28 (*, P < 0.05). (E and F) Numbers of LALN (E) and lung (F) CD4⁺ lymphocytes in mice consuming the LED and LCD diets, but not infected with M. tuberculosis, at days 14 and 28. There were no differences between the groups at either site at either time point. Error bars indicate standard errors of the means.
