Glycosyltransferases, glycosylation and atherosclerosis

Area of Science:

• Biochemistry
• Immunology
• Cardiovascular Research

Background:

• Atherosclerosis is a major global cause of mortality.
• Leukocyte recruitment in inflamed endothelium is critical for atherosclerosis initiation.
• Leukocyte recruitment involves glycosylated adhesive molecules and chemokine receptors.

Purpose of the Study:

• To review recent data on the roles of various glycosyltransferases in atherogenesis.
• To highlight the necessity of post-translational glycosylation for leukocyte adhesion molecule function.
• To explore the potential of targeting glycosyltransferases for novel therapeutic strategies.

Main Methods:

• Review of current scientific literature on glycosyltransferases and atherogenesis.
• Analysis of the role of specific glycosyltransferases (e.g., sialyltransferases, fucosyltransferases) in leukocyte recruitment.
• Discussion of the impact of glycosylation on adhesive molecules and chemokine receptors.

Main Results:

• Post-translational glycosylation by glycosyltransferases is essential for the activity of adhesive molecules and chemokine receptors.
• Specific glycosyltransferases, including α2,3-sialyltransferases IV, α1,3-fucosyltransferases IV and VII, and core 2 β1,6-N-acetylglucosaminyltransferase-I, are implicated in atherosclerotic lesion initiation.
• Glycosylation patterns on these molecules influence leukocyte recruitment and subsequent atherogenesis.

Conclusions:

• Glycosyltransferases play a significant role in the initiation and progression of atherosclerosis.
• Understanding the function of glycosyltransferases in atherogenesis provides a basis for developing new treatments.
• Targeting specific glycosyltransferases may offer a novel therapeutic approach to combat cardiovascular diseases.
