High glucose thickens cancer cells' sugar shield, helping them evade immune attack

Researchers have discovered that high glucose levels enable cancer cells to build thicker coats of sugar-derived molecules, creating a protective shield that helps them evade detection by the immune system. These sugar coatings act like disguises, allowing cancer cells to hide from the body's natural defenses. This finding provides critical insight into how cancer metabolism supports tumor growth and immune evasion. Understanding this mechanism could lead to new therapeutic strategies that disrupt these sugar shields, potentially making cancer cells more vulnerable to immune attacks and improving treatment outcomes.
