Stressed: The Unfolded Protein Response in T Cell Development, Activation, and Function.

Area of Science:

• Immunology
• Cellular Biology
• Molecular Biology

Background:

• The unfolded protein response (UPR) is a cellular stress response pathway.
• UPR regulates endoplasmic reticulum (ER) homeostasis, critical for protein folding and trafficking.
• Secretory cells heavily rely on proper protein folding within the ER.

Purpose of the Study:

• To review the critical role of UPR in T cell development and function.
• To highlight the underappreciated involvement of UPR in T cell biology.
• To explore therapeutic potential of manipulating UPR in T cells.

Main Methods:

• Literature review focusing on UPR and T cell interactions.
• Analysis of existing research on UPR's impact on T cell processes.
• Synthesis of information regarding UPR's role in T cell homeostasis, activation, and effector functions.

Main Results:

• UPR is essential for proper T cell development and maintenance.
• UPR influences T cell activation and effector functions.
• Dysregulation of UPR in T cells can contribute to pathologies.

Conclusions:

• UPR plays a significant role in T cell biology beyond its known functions in immunity.
• Targeting UPR in T cells presents a potential therapeutic strategy for immune-related diseases.
• Further research is needed to fully elucidate and exploit UPR's role in T cell-mediated pathologies.
