CD40LG and breast cancer: When the expression of the different TNF family molecules on platelets from BC and CC patients and HD was comparatively analyzed, we surprisingly found that, except for CD40L in CC, median relative expression of all analyzed molecules was slightly lower on platelets from BC and CC patients compared to median results obtained with HD (Figure 3D; BC, OX40L, p = 0.0418; Kruskal-Wallis test with subsequent Dunnett’s multiple comparisons test).
