Longistatin in tick saliva blocks advanced glycation end-product receptor activation.

Ticks are notorious hematophagous ectoparasites and vectors of many deadly pathogens. As an effective vector, ticks must break the strong barrier provided by the skin of their host during feeding, and their saliva contains a complex mixture of bioactive molecules that paralyze host defenses. The receptor for advanced glycation end products (RAGE) mediates immune cell activation at inflammatory ...

Longistatin in tick-saliva targets RAGE

Ticks are obligatory blood-sucking ectoparasites and while feeding for a single blood-meal, ticks remain attached to hosts by firmly embedding their barbed mouthparts for several days. Like mosquitoes, they cannot canulate an individual blood vessel; rather, they cause extensive damage in vascular beds and underlying tissues leading to the development of a blood pool, a feeding lesion of ticks....

Blocking the receptor for advanced glycation end product activation attenuates autoimmune myocarditis.

BACKGROUND The Receptor for Advanced Glycation End Products (RAGE) is a pattern recognition receptor for endogenous ligands, and is associated with various inflammatory diseases. However, the role of RAGE activation in myocarditis has yet to be examined. The potential role of RAGE in the development of experimental autoimmune myocarditis (EAM) and the effect of RAGE blocking in attenuating the ...

The role of autophagy in advanced glycation end product-induced proliferation and migration in rat vascular smooth muscle cells

Objective(s): To investigate the role of autophagy in advanced glycation end products (AGEs)-induced proliferation and migration in rat vascular smooth muscle cells (VSMCs).Materials and Methods: After culture, VSMCs were treated with 0, 1, 10, and 100 μg/ml concentrations of AGEs. Autophagy specific protein light chain 3 (LC3)-I/II was determined by western blotting, autophagosomes were observ...

Advanced Glycation End-Products and Their Receptor-Mediated Roles: Inflammation and Oxidative Stress

Glycation is a protein modification, which results in a change in a protein structure. Glycation is believed to be the etiology of various age-related diseases such as diabetes mellitus and Alz-heimer’s disease (AD). Activation of microglia and resident macrophages in the brain by glycated proteins with subsequent oxidative stress and cytokine release may be an important factor in the progressi...
