pUL11Fc modulates T cell proliferation in a dose dependent manner.

<p>PBMCs were either left unstimulated or stimulated with anti-CD3 (OKT3) together with the indicated concentrations of UL11Fc derived from HCMV strain (A) TB40 or (B) Merlin or with the Fc control protein. Single representative experiments from four (A) or two (B) replicates are shown; error bars show standard deviation of technical replicates.</p>
