CD27 expression recovers on lymphocytes following treatment with collagenase.

<p>(A) Dot plots show collagenase treated PBMCs lose surface CD27 expression, but expression is almost entirely recovered after 4, and entirely recovered after 24 hrs rest / incubation. Numbers in each quadrant indicate the percentage of total live lymphocytes as indicated in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0116667#pone.0116667.g001" target="_blank">Fig. 1</a>. (B) Rapid recovery of CD27 expression on collagenase treated cells occurs in all tissues including intestinal tissues. Histograms are representative of four independent experiments.
