How RNA Changes Affect T Cell Immunity, Disease, and Treatment Possibilities

RNA modifications may influence T lymphocyte function and immune responses.

• Chemical marks like N-methyladenosine (mA), 5-methylcytosine (mC), and pseudouridine (Ψ) are involved in regulating transcript stability and protein production in T cells.
• These modifications are linked to T cell functions such as lineage specification, activation thresholds, and immune tolerance.
• Dysregulation of RNA modifications can contribute to various conditions, including infections, autoimmunity, and cancer.
• Distinct RNA modifications appear to converge on shared molecular pathways that control T cell behavior and responses.
• Altered modification patterns may change cytokine production and metabolic processes in T cells, affecting disease outcomes.
• Challenges remain in understanding the timing and location of RNA modifications and developing targeted therapies based on these mechanisms.
