Research progress on targeted protein S-palmitoylation modification in T cell immunotherapy

S-palmitoylation, a reversible and dynamic post-translational modification in cells, is involved in regulating the transcription and expression of downstream target genes as well as signal transduction, thereby affecting cell life activities. Studies have shown that thousands of human proteins undergo S-palmitoylation modification, suggesting that S-palmitoylation is closely related to the progression and treatment of diseases. T cells play central roles in anti-tumor immune responses. A variety of T cell immune-related proteins are regulated by S-palmitoylation. In the present study, we focus on the impact of S-palmitoylation on T cell signal transduction and its application in T cell immunotherapy, aiming to provide new ideas for the development of new targets and peptide inhibitors for T cell immunotherapy.
