<h2>Intestinal Epithelial Cells (IEC)</h2>
Explanation:
- <em>Polarized intestinal epithelial cells (IEC),</em> as well as the resident microflora, provide a barrier that guards <em>against microbial invasion</em>
- The necessity for the <em>epithelium </em>to maintain an intact barrier between <em>lumen bacteria</em> and the lamina propria is exemplified by the consequences after the barrier function is altered
- Impairment of the barrier function of the <em>intestinal epithelium may be a predominant mechanism in the pathogenesis of inflammatory bowel disease (IBD)</em>
