From: Natural OX40L expressed on human T cell leukemia virus type-I-immortalized T cell lines interferes with infection of activated peripheral blood mononuclear cells by CCR5-utilizing human immunodeficiency virus

Figure 3

Blocking (clone W4-54) versus non-blocking (clone B-7B5) mAb against 2 distinct epitopes of OX40 distinguish between OX40L bound and unbound OX40. (A) OX40-expressing CEM and activated PBMCs were stained with the two mAbs in the absence (mock) or presence of 1 μg/ml of recombinant OX40L (rec-OX40L). (B) Various HTLV-1+ T cell lines were stained with B-7B5 andW4-54 labeled with FITC and Cy5, respectively. Data shown are representative of 3 independent experiments.
