4-Hydroxy-2-hexenal Antibody, Clone 6F10: ATTO 488

Lipid peroxidation, driven by oxidative stress, targets carbon-carbon double bonds in polyunsaturated fatty acids (PUFAs), leading to membrane damage and the generation of reactive aldehydes. Among these, 4-Hydroxy-2-hexenal (4-HHE) is a major α, β-unsaturated aldehyde derived specifically from the oxidation of n-3 PUFAs. Emerging evidence highlights 4-HHE as a critical mediator of neuronal injury and a potential biomarker in neurodegenerative disease. 4-HHE is highly electrophilic and forms stable Michael addition adducts with nucleophilic amino acid residues, particularly histidine. These covalent modifications disrupt protein structure and function, impairing key cellular processes such as mitochondrial respiration, synaptic signaling, and proteostasis. Elevated levels of 4-HHE have been observed in various pathological states, including Alzheimer’s disease, Parkinson’s disease, and amyotrophic lateral sclerosis (ALS), implicating it in the progression of oxidative damage and chronic neuroinflammation. In neuroscience research, 4-HHE is gaining attention for its dual role as both a marker of lipid peroxidation and an active contributor to neurotoxicity. Its ability to alter neuronal viability and promote apoptotic pathways underscores its relevance in the study of aging and neurodegeneration. Understanding the molecular mechanisms of 4-HHE toxicity is essential for developing targeted antioxidant therapies and early diagnostic tools in neurodegenerative disease research.
