MetabolomicsPalmitic Acid-Triggerd B7H3 Palmitoylation Promotes Immune Escape

B7H3 (CD276), a key immune checkpoint molecule that is overexpressed in tumors, plays a central role in cancer progression, making it a highly promising and specific therapeutic target. Here, we discovered that the cellular metabolite palmitic acid contributes to the development of an immunosuppr...

MetabolomicsCD36 palmitoylation regulates the lipid metabolic homeostasis

Alterations in myocardial energy substrate metabolism following myocardial infarction (MI) results in structural and functional abnormalities of the heart. The fatty acid translocase CD36 (CD36), acrucial membrane protein, plays a pivotal role in regulating fatty acid (FA) uptake and lipid homeos...

ProteomicsAttenuated palmitoylation of serotonin receptor 5-HT1A in brain affects receptor functions and triggers depressive symptoms
The serotonergic system and in particular serotonin 1A receptor (5-HT1AR) are critically implicated in major depressive disorder (MDD), although underlying mechanisms remain enigmatic. Here we demonstrated that 5-HT1AR is palmitoylated in human and rodent brains and identified ZDHHC21 as a major pa...

ProteomicsTargeting APT2 improves MAVS palmitoylation and antiviral innate immunity
Innate immunity serves as the primary defense against viral and microbial infections in humans. Among its components, retinoic acid-inducible gene I (RIG-I)-like receptors (RLRs) are well-characterized intracellular pattern-recognition proteins that trigger innate immune responses upon viral infecti...

ProteomicsDirect identification of protein S-palmitoylation sites
S-fatty-acylation is the covalent attachment of long chain fatty acids, predominately palmitate (C16:0, S-palmitoylation), to cysteine (Cys) residues via a thioester linkage on proteins. This post-translational and reversible lipid modification regulates protein function and localization in eukaryot...

ProteomicsTLR9-Driven S-Palmitoylation in Dendritic Cells Reveals Immune and Metabolic Protein Targets
Dendritic cells (DCs) rely on Toll-like receptor 9 (TLR9) to detect unmethylated CpG motifs in microbial DNA, triggering essential immune responses. While the downstream signaling pathways of TLR9 activation are well characterized, their impact on S-palmitoylation is unknown. S-palmitoylation, invol...

ProteomicsPalmitoylation couples insulin hypersecretion with β-cell failure in diabetes
Hyperinsulinemia often precedes type 2 diabetes but its role in disease progression is unknown. Palmitoylation, a protein modification implicated in regulated exocytosis, is reversed by acyl-protein thioesterase 1 (APT1). We found altered APT1 biology in pancreatic islets from humans with type 2 dia...

Protein palmitoylation, also known as S-acylation, is a reversible post-translational modification in which fatty acids are covalently attached to cysteine residues via thioester bonds. To date, protein palmitoylation has been well studied in animal cells, where it plays a crucial role in regulating...
