T cell receptor V beta expression in human intestine: regional variation in postnatal intestine and biased usage in fetal gut

Record type: Article

A panel of T cell receptor V beta specific monoclonal antibodies was used to analyse V beta gene usage at different sites in human postnatal and fetal intestine. In normal small intestine, at a single site, different patients showed expansion of T cells expressing individual V beta s. Lamina propria and epithelial T cells from the same patient showed overlapping but not identical V beta dominance. V beta dominance was also shown in the T cells of the colonic lamina propria. Analysis of two separate regions of intestine from the same patient (5-100 cm apart) showed that T cells expressing a dominant V beta region were often present at both sites. In most patients, however, major biases in T cell V beta usage (two to 12-fold variation) were also apparent between the two sites. Analysis of V beta expression in human fetal intestine also showed considerable skewing, although the most common dominant V beta in postnatal intestine (V beta 22) was never predominant in fetal intestine. Patchy local variation in the expression of individual V beta s therefore occurs against a background of V beta dominance over large regions of the human gut. Furthermore the results from fetal gut show that factors other than luminal antigen control V beta expression in the gut.
