Objective(s): The present paper aims to review the studies describing the interactions between HopQ and CEACAMs along with possible mechanisms responsible for pathogenicity of Helicobacter pylori.Materials and Methods: The literature was searched on “PubMed” using different key words including Helicobacter pylori, CEACAM and gastric.<br ...

Background: Inflammation is involved in development, progression, and complications of atherosclerotic disease. Clinical studies have indicated that the level of monocyte chemoattractant protein 1 (MCP-1), IL-18, and adhesion molecules correlates with the severity of atherosclerosis and can predict future cardiovascular events. Experimental studies have shown pentoxifylline (PTX) reduces these ...

During embryonic development of the cerebellum, Purkinje cells (PCs) migrate away from the ventricular zone to form the PC plate. The mechanisms that regulate PC migration are incompletely understood. Here, we report that the neurotrophic receptor GFRα1 is transiently expressed in developing PCs and loss of GFRα1 delays PC migration. Neither GDNF nor RET, the canonical GFRα1 ligand and co-recep...

More precise information on the degree of polymerization (DP) of polysialic acid (polySia) chains expressed on neural cell adhesion molecule (NCAM) and its developmental stage-dependent variation are considered important in understanding the mechanism of regulated polysialylation and fine-tuning of NCAM-mediated cell adhesion by polySia. In this paper, first we performed a kinetic study of acid...

Considerable advances have been made in our knowledge of the molecular structure of cell adhesion molecules, their binding sites, and adhesion complexes. For the cadherins, protein zero, and CD2, additional experimental data support the insights obtained from structural analysis of their domains and molecular models of their adhesion complexes. For neural cell adhesion molecules, L1, fibronecti...

The neural cell adhesion molecule (NCAM) is the major substrate for the polysialyltransferases (polySTs), ST8SiaII/STX and ST8SiaIV/PST. The polysialylation of NCAM N-glycans decreases cell adhesion and alters signaling. Previous work demonstrated that the first fibronectin type III repeat (FN1) of NCAM is required for polyST recognition and the polysialylation of the N-glycans on the adjacent ...

trans-fatty acids (tfa) are known as a risk factor for coronary artery diseases. trans-11 vaccenic acid [va; 18:1(n-9)], known as the major trans fatty acid in milk fat, is a positional and geometric isomer of oleic acid and a precursor of conjugated linoleic acid (cla) in human . this study was carried out in order to investigate the effect of cis and trans vaccenic acids on expression of intr...
