TRAIL and Cardiovascular Disease—A Risk Factor Or Risk Marker: a Systematic Review

Data from animal studies indicate that TRAIL may possibly contribute to the pathophysiology of cardiomyopathy, atherosclerosis, ischemic stroke and abdomi- nal aortic aneurysm. It has been also suggested that TRAIL might be useful in cardiovascular risk stratification. This systematic review aimed to evaluate whether TRAIL is a risk factor or risk marker in cardiovascular diseases (CVDs) focusing on major adverse cardiovascular events. Two databases (PubMed and Cochrane Library) were searched until December 2020 without a year limit in accor- dance to the PRISMA guidelines. A total of 63 eligible original studies were identified and included in our systematic review. Studies suggest an important role of TRAIL in disorders such as heart failure, myocardial infarction, atrial fibrillation, ischemic stroke, peripheral artery disease, and pul- monary and gestational hypertension. Most evidence associates reduced TRAIL levels and increased TRAIL-R2 concentration with all-cause mortality in patients with CVDs. It is, however, unclear Citation: Kakareko, K.; whether low TRAIL levels should be considered as a risk factor rather than a risk marker of CVDs. -

The CD44-Initiated Pathway of T-Cell Extravasation Uses VLA-4 but Not LFA-1 for Firm Adhesion
The CD44-initiated pathway of T-cell extravasation uses VLA-4 but not LFA-1 for firm adhesion Mark H. Siegelman, … , Diana Stanescu, Pila Estess J Clin Invest. 2000;105(5):683-691. https://doi.org/10.1172/JCI8692. Article Leukocytes extravasate from the blood in response to physiologic or pathologic demands by means of complementary ligand interactions between leukocytes and endothelial cells. The multistep model of leukocyte extravasation involves an initial transient interaction (“rolling” adhesion), followed by secondary (firm) adhesion. We recently showed that binding of CD44 on activated T lymphocytes to endothelial hyaluronan (HA) mediates a primary adhesive interaction under shear stress, permitting extravasation at sites of inflammation. The mechanism for subsequent firm adhesion has not been elucidated. Here we demonstrate that the integrin VLA-4 is used in secondary adhesion after CD44-mediated primary adhesion of human and mouse T cells in vitro, and by mouse T cells in an in vivo model. We show that clonal cell lines and polyclonally activated normal T cells roll under physiologic shear forces on hyaluronate and require VCAM-1, but not ICAM-1, as ligand for subsequent firm adhesion. This firm adhesion is also VLA-4 dependent, as shown by antibody inhibition. Moreover, in vivo short-term homing experiments in a model dependent on CD44 and HA demonstrate that superantigen-activated T cells require VLA-4, but not LFA-1, for entry into an inflamed peritoneal site. Thus, extravasation of activated T cells initiated by CD44 binding to HA depends upon VLA-4–mediated firm adhesion, which may explain the frequent association of these adhesion receptors with diverse chronic inflammatory processes. -
Chimeric Form of Tumor Necrosis Factor-A Has Enhanced Surface
Cancer Gene Therapy (2009) 16, 53–64 r 2009 Nature Publishing Group All rights reserved 0929-1903/09 $32.00 www.nature.com/cgt ORIGINAL ARTICLE Chimeric form of tumor necrosis factor-a has enhanced surface expression and antitumor activity R Rieger1, D Whitacre1, MJ Cantwell1,3, C Prussak2 and TJ Kipps1 1Department of Medicine, Moores Cancer Center, University of California, San Diego, La Jolla, CA, USA and 2Memgen, LLC, Solana Beach, CA, USA Tumor necrosis factor (TNF)-a is a type-II transmembrane protein that is cleaved by TNF-a-converting enzyme (TACE/ADAM-17) to release soluble TNF, a cytokine with potent antitumor properties whose use in clinical applications is limited by its severe systemic toxicity. We found that human cells transfected with vectors encoding TNF without the TACE cleavage site (DTACE-TNF) still released functional cytokine at substantial levels that varied between transfected cell lines of different tissue types. Vectors encoding membrane-associated domains of CD154, another TNF-family protein, conjoined with the carboxyl-terminal domain of TNF, directed higher-level surface expression of a functional TNF that, in contrast to DTACE-TNF, was resistant to cleavage in all cell types. Furthermore, adenovirus vectors encoding CD154-TNF had significantly greater in vivo biological activity in inducing regression of established, syngeneic tumors in mice than adenovirus vectors encoding TNF, and lacked toxicity associated with soluble TNF. As such, CD154-TNF is a novel TNF that appears superior for treatment of tumors in which high-level local expression of TNF is desired.

Regulation of Cellular Adhesion Molecule Expression in Murine Oocytes, Peri-Implantation and Post-Implantation Embryos
Cell Research (2002); 12(5-6):373-383 http://www.cell-research.com Regulation of cellular adhesion molecule expression in murine oocytes, peri-implantation and post-implantation embryos 1,2 1,2 2 1, DAVID P LU , LINA TIAN , CHRIS O NEILL , NICHOLAS JC KING * 1Department of Pathology, University of Sydney, NSW 2006 Australia 2Human Reproduction Unit, Department of Physiology, University of Sydney, Royal North Shore Hospital, NSW 2065, Australia ABSTRACT Expression of the adhesion molecules, ICAM-1, VCAM-1, NCAM, CD44, CD49d (VLA-4, α chain), and CD11a (LFA-1, α chain) on mouse oocytes, and pre- and peri-implantation stage embryos was examined by quantitative indirect immunofluorescence microscopy. ICAM-1 was most strongly expressed at the oocyte stage, gradually declining almost to undetectable levels by the expanded blastocyst stage. NCAM, also ex- pressed maximally on the oocyte, declined to undetectable levels beyond the morula stage. On the other hand, CD44 declined from highest expression at the oocyte stage to show a second maximum at the com- pacted 8-cell/morula. This molecule exhibited high expression around contact areas between trophectoderm and zona pellucida during blastocyst hatching. CD49d was highly expressed in the oocyte, remained signifi- cantly expressed throughout and after blastocyst hatching was expressed on the polar trophectoderm. Like CD44, CD49d declined to undetectable levels at the blastocyst outgrowth stage. Expression of both VCAM- 1 and CD11a was undetectable throughout. The diametrical temporal expression pattern of ICAM-1 and NCAM compared to CD44 and CD49d suggest that dynamic changes in expression of adhesion molecules may be important for interaction of the embryo with the maternal cellular environment as well as for continuing development and survival of the early embryo.
