Summary
T cells manage endoplasmic reticulum (ER) stress through various mechanisms. Dysregulation of ER stress impacts T cell function and contributes to autoimmune diseases and cancer.
Area of Science:
- Immunology
- Cell Biology
- Molecular Biology
Background:
- T cells synthesize numerous proteins during development and activation.
- Accumulation of misfolded proteins in the endoplasmic reticulum (ER) leads to ER stress.
- ER homeostasis is maintained by ER-associated degradation, unfolded protein response, and autophagy.
Purpose of the Study:
- To review the role of ER stress in T cell biology.
- To discuss the impact of ER stress on T cell-mediated diseases.
- To offer new perspectives on T cells in autoimmune disorders and cancer.
Main Methods:
- Literature review of T cell function and ER stress.
- Analysis of ER stress in T cell development, activation, and differentiation.
- Examination of ER stress in T cell-mediated diseases.
Main Results:
- ER stress is a critical factor in T cell homeostasis.
- Altered ER stress contributes to the progression of autoimmune diseases.
- ER stress influences T cell roles in cancer.
Conclusions:
- ER stress is integral to T cell function and dysfunction.
- Targeting ER stress pathways may offer therapeutic strategies for autoimmune diseases and cancer.
- Understanding ER stress in T cells provides insights into immune-mediated pathologies.

01:17Role of ER in the Secretory Pathway
5.4K
Eukaryotic cells have a special pathway that enables communication between various intracellular membrane-bound compartments and also with the extracellular environment. This pathway is termed as the secretory pathway.
Components of the secretory pathway
About a third of proteins synthesized in the cell are sorted via the secretory route. They shuffle between different compartments in membrane-bound vesicles until they reach their final destination. The main intracellular compartments involved...

01:24T Cell Types and Functions
1.0K
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.

01:31Regulation of the Unfolded Protein Response
2.4K
Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...

01:37The Unfolded Protein Response
4.6K
The ER is the hub of protein synthesis in a cell. It has robust systems to quality control protein folding and also for degradation of terminally misfolded proteins. Under normal conditions, a small proportion of misfolded proteins that cannot be salvaged need to be transported to the cytoplasm by the ER-associated degradation or ERAD pathways. However, if the ERAD cannot handle the misfolded proteins, the cell activates the unfolded protein response or UPR to adjust the protein folding...

01:29Protein Folding Quality Check in the RER
3.7K
ER is the primary site for the maturation and folding of soluble and transmembrane secretory proteins. The calnexin cycle is a specific chaperone system that folds and assesses the confirmation of N-glycosylated proteins before they can exit the ER lumen. The primary players of this quality check pipeline are the lectins, ER-resident chaperones, and a glucosyl transferase enzyme. In case the calnexin system in the lumen fails to salvage a misfolded protein, it is transported to the cytoplasm...

01:22T Cell Activation and Clonal Selection

T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.
