The physiological and pathological roles of RNA modifications in T cells

Area of Science:

• Immunology
• Molecular Biology
• Epitranscriptomics

Background:

• RNA molecules possess dynamic chemical modifications influencing cellular processes.
• These modifications post-transcriptionally regulate gene expression, affecting cell fate and function, especially in T cells.
• T cells are critical for adaptive immunity, and their functions are increasingly linked to RNA modifications.

Purpose of the Study:

• To review the physiological and pathological roles of internal RNA modifications in T cell biology.
• To elucidate how RNA modifications impact T cell development, differentiation, and functionality.
• To highlight the potential of targeting RNA modifications for T cell-based immunotherapy.

Main Methods:

• Literature review of current research on RNA modifications and T cell biology.
• Analysis of studies detailing the impact of epitranscriptomic changes on T cell functions.
• Synthesis of findings to identify therapeutic opportunities.

Main Results:

• RNA modifications significantly modulate T cell survival, proliferation, differentiation, and effector functions.
• Epitranscriptomic control plays a crucial role in T cell-mediated immunity and disease pathogenesis.
• Specific RNA modifications are implicated in various aspects of T cell biology.

Conclusions:

• Understanding RNA modifications in T cells is key to deciphering adaptive immunity.
• Epitranscriptomic insights provide novel avenues for manipulating T cell immunity.
• Targeting RNA modifications presents promising prospects for developing T cell-based immunotherapies.
