PURPOSE Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL/Apo2L) exhibits potent antitumor activity on systemic administration in nonhuman primates without deleterious side effects for normal tissue. However, there is a controversy about the potential toxicity of TRAIL on human hepatocytes. The use of different recombinant TRAIL forms only partially explains the contradicting repor...

In previous studies, we have shown that tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) could induce varying degrees of apoptosis in approximately two-thirds of human melanoma lines. In the present study, we have examined the sensitivity of fresh isolates and early passages of melanoma cells to TRAIL-induced apoptosis from eight patients. We found that fresh isolates were relati...

OBJECTIVE To determine the potential immediate applicability of tumor necrosis factor-related apoptosis-inducing ligand receptor 1 (TRAIL-R1) and TRAIL-R2, the apoptotic forms of TRAIL-Rs, for preclinical testing. DESIGN AND SETTING Head and neck squamous cell carcinoma (HNSCC) tumors were studied for TRAIL-R1 and TRAIL-R2 expression by immunohistochemical analysis. In addition, matched tumor...

TNF-related apoptosis-inducing ligand (TRAIL) is able to kill many transformed cells of diverse tissue types. We show that TRAIL is inducible by IFN-gamma, by TNF-alpha, and by infection with human CMV, and has potent antiviral activity in vitro. CMV infection and IFN-gamma also reciprocally modulate TRAIL receptor (TRAIL-R) expression. CMV infection increased the expression of TRAIL-R1 and -R2...

Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) triggers apoptosis selectively in tumor cells through interaction with TRAIL-R1/DR4 or TRAIL-R2/DR5 and this process is considered a promising avenue for cancer treatment. TRAIL resistance, however, is frequently encountered and hampers anti-cancer activity. Here we show that whereas H460 non-small cell lung cancer (NSCLC) ce...

production of TNF-related apoptosis-inducing ligand (TRAIL), an inducer of apoptosis and a cancer therapeutic (Figure 4B) (Johnstone et al., 2008; Lemke et al., 2014). T cells normally do not produce TRAIL upon TCR stimulation, therefore, if synthetically expressed in a controlledmanner, this could aid in their cytotoxic activity (Figure S4A). Soluble forms of TRAIL are effective at killing the...

TNF-related apoptosis-inducing ligand (TRAIL; Apo2) has been shown to promote intestinal cell differentiation. Nuclear factor of activated T cells (NFAT) participates in the regulation of a variety of cellular processes, including differentiation. Here, we examined the role of NFAT in the regulation of TRAIL in human intestinal cells. Treatment with a combination of phorbol 12-myristate 13-acet...

BACKGROUND TRAIL protein is expressed in the medial smooth cell layer of aorta and pulmonary artery, whereas endothelial cells express all TRAIL receptors (TRAIL-Rs). METHODS AND RESULTS The role of TRAIL/TRAIL-Rs in vascular biology was investigated in primary human umbilical vein endothelial cells (HUVECs) and aortic endothelial cells, which showed comparable surface expression of death (TR...

TRAIL is a member of the TNF superfamily that induces tumor-selective cell death by engaging the pro-apoptotic death receptors DR4 and DR5. The antitumor potential of the TRAIL pathway has been targeted by several therapeutic approaches including recombinant TRAIL and TRAIL-receptor agonist antibodies among others. Interest in sensitizing tumor cells to TRAIL-mediated apoptosis has driven inves...

BACKGROUND Tumor necrosis factor-related apoptosis inducing ligand (TRAIL) induces apoptosis of tumor cells but not normal cells; its role in normal non-transformed tissues is unknown. OBJECTIVE To evaluate the role of apoptosis mediated by TRAIL and TRAIL-receptor (TRAIL-R) system in lymphocytic sialadenitis in patients with Sjögren's syndrome. METHODS The expression of TRAIL and TRAIL-R1,...
