OBJECTIVE Repetitive interaction with microbial stimuli renders epithelial cells (ECs) hyporesponsive to microbial stimulation. Previously, we have reported that buccal ECs from a subset of paediatric patients with Crohn's disease are not hyporesponsive and spontaneously released chemokines. We now aimed to identify kinetics and mechanisms of acquisition of hyporesponsiveness to microbial stimu...
Aerobic and anaerobic bacteria isolated from human axillae were tested for their capacity to adhere to buccal epithelial cells, immortalized human epithelial (HEp-2) cells, and undifferentiated and differentiated human epithelial cells. In general, both aerobic and anaerobic diphtheroids adhered better to differentiated human epithelial cells than to HEp-2 and undifferentiated human epithelial ...
S-fimbriated Escherichia coli, which cause sepsis and meningitis in the newborn, bind to sialic acid-containing glycoprotein structures on the surface of human buccal epithelial cells. The dependence of this binding on host age was examined. S-fimbriated E. coli adhered in comparable numbers to cells in newborns, infants, children and adults (23.0 +/- 8.6; 23.1 +/- 11.5; 24.7 +/- 7.9; 28.9 +/- ...
Background: Down syndrome (DS) is a most common cause of mental retardation in humans. Monitoring genetic damage in DS individuals helps in evaluating genetic damage. Micronucleus assay is potentially an excellent tool to serve as a biomarker which detects chromosomal loss or malfunction. Aim of the study: The objective of the study is to evaluate micronuclei (MN) frequency in exfoliated buccal...
Oral cancer is most common cancer in males and third most common in females, the main causative agent being use of chewing betel quid (BQ). The micronucleus (MN) assay in exfoliated buccal cells is a useful and minimally invasive method for monitoring genetic damage in humans. Micronuclei (MN) have been proposed as good biomarker to assess cytogenetic damage. MN formation has been observed in c...
