We reproducibly demonstrated that our monolayers permitted less than 1% inulin diffusion, one standard for polarization of Caco-2 cells; however, this may not have been sufficient to completely block LTA diffusion.
Streptococcus mutans in which DCP is inactive do not initiate growth at below pH 6.5 and make glycerol LTA without D-alanine [ 14 ] . In the DCP active strains, soluble D-Alanyl LTA is extruded into culture fluid in vitro [ 16 17 ] or plaque in vivo [ 18 ] . The D-alanyl esters are stable at pH 6.0 at 37°C, but hydrolyze to free D-alanine and LTA with a half-life of 3.9 h at pH 8.0 [ 19 ] . Healthy gingival sulci have a pH of 6.5 - 7.5 and inflamed sulci a pH of 7.5-8.
The student, patient and volunteer populations (397 subjects) were used to determine what IgG concentration constituted an elevated antibody response to D-alanyl LTA, to ensure that these antibodies were not unique to dental or Oklahoma populations and to examine whether the antibody concentration was sex or age-associated.
