Summary
Stimulator of interferon genes (STING) is a key pattern recognition receptor (PRR) in innate immunity. This review explores STING
Area of Science:
- Immunology
- Microbiology
- Pharmacology
Background:
- Antibiotic-resistant bacteria pose a significant global health threat.
- Innate immunity, utilizing pattern recognition receptors (PRRs), is the first line of defense against bacterial infections.
- Stimulator of interferon genes (STING) is a PRR involved in sensing 'non-self' components and initiating immune responses.
Purpose of the Study:
- To review research progress on STING signaling pathways in bacterial infections.
- To explore the novel functions of STING modulators.
- To provide insights for developing new antibacterial drugs targeting the STING pathway.
Main Methods:
- Literature review of studies on STING signaling in bacterial infections.
- Analysis of STING's role in host-pathogen interactions.
- Examination of existing and potential STING modulators.
Main Results:
- STING plays a crucial role in host defense against various pathogens, including bacteria.
- STING activation induces type I interferon, inflammatory cytokines, and regulated cell death.
- Current STING-targeting drugs are primarily used for cancer and viral infections, with limited application in bacterial infections.
Conclusions:
- STING signaling is a promising target for novel antibacterial therapies.
- Further research into STING modulators could lead to effective treatments for bacterial infections.
- Understanding STING's immunomodulatory functions is vital for combating antibiotic resistance.

Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...

Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. Additionally, cells often need to communicate with one another. Unicellular and multicellular organisms use a variety of cell signaling mechanisms to communicate with the environment.
Cells respond to many types of information, often through receptor proteins positioned on the membrane. For example, skin cells respond to and transmit touch...

Cells respond to many types of information, often through receptor proteins positioned on the membrane. They respond to chemical signals, such as hormones, neurotransmitters, and other signaling molecules, initiating a series of molecular reactions to produce an appropriate response. This is called signal transduction. Cells also coordinate different responses elicited by the same signaling molecule via mediators, allowing molecular cross-talk.

Quorum sensing is a mechanism of bacterial communication that enables coordinated gene expression in response to changes in population density. This facilitates collective behaviors that enhance survival, resource acquisition, and ecological adaptation. This process relies on small signaling molecules called autoinducers that accumulate as bacterial populations grow. When a critical threshold concentration of autoinducers is reached, bacterial cells collectively modify gene expression,...

Global regulatory systems in bacteria enable rapid and coordinated responses to environmental changes by integrating sensory inputs with gene expression, ensuring efficient adaptation to fluctuating conditions. Key global regulatory mechanisms include regulons, two-component systems, sigma factors, and secondary messengers.Regulons and Global RegulatorsA regulon is a collection of genes and operons controlled by a common global regulator. These regulators enable bacteria to prioritize resource...

Once a ligand binds to a receptor, the signal is transmitted through the membrane and into the cytoplasm. The continuation of a signal in this manner is called signal transduction. Signal transduction only occurs with cell-surface receptors, which cannot interact with most components of the cell, such as DNA. Only internal receptors can interact directly with DNA in the nucleus to initiate protein synthesis. When a ligand binds to its receptor, conformational changes occur that affect the...
