T-cell repertoire is different between tissues but not between GF and colonised pigs.

Principle component analysis of CDR3 lengths for all V beta families was performed for a maximum of 25 iterations for convergence using an un-rotated factor solution. Table 2 shows the p-values from a fully factorial general linear model of the first five principal components with colonisation status (GF or colonised) and tissue as fixed factors. A p-value of <0.01 was considered significant using a Bonferroni correction for 5 tests.
