Tuberculosis infection triggers endoplasmic-reticulum stress (ERS) to manage misfolded proteins. Uncontrolled ERS signaling pathways can lead to cell death, aiding mycobacterial spread.
Area of Science:
- Cellular Biology
- Immunology
- Microbiology
Background:
- Tuberculosis (TB) is a significant global health issue.
- Mycobacterial infection induces endoplasmic-reticulum stress (ERS), a cellular response to protein misfolding.
- The unfolded protein response (UPR) is activated to restore ER homeostasis.
Purpose of the Study:
- To summarize recent advancements in understanding ERS signaling pathways in TB.
- To explore the role of ERS in the host-pathogen interaction during TB.
Main Methods:
- Literature review of recent research on ERS and TB.
- Analysis of signaling pathways involved in the UPR (IRE1, PERK, ATF6).
Main Results:
- ERS is a critical cellular process in response to mycobacterial infection.
- Dysregulated ERS and UPR can lead to apoptosis, impacting TB pathogenesis.
- Specific signaling pathways (IRE1, PERK, ATF6) govern ERS outcomes.
Conclusions:
- Understanding ERS signaling diversity is crucial for TB research.
- Targeting ERS pathways may offer novel therapeutic strategies for TB.

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...

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
