Box and whisker plots are provided for proportions of T cells expressing each integrin, with individual data points represented by dots. Comparisons are in reference to PBMC, with p values from Mann-Whitney U tests given for each site. NS= non-significant, p≥ 0.05. (a) TCD4 (b) TCD8. Examples of individual sample multiparameter flow cytometry for expression of α4b7 are shown for TCD4 (c) with event counts (left to right) 2,181; 2,448; 1,632. N = number of samples in each category. NLN = normal lymph node. TIN = tumor-infiltrated lymph node.
