Abstract:
Persister cells are transiently antibiotic-tolerant and dormant subpopulations that are produced to escape the effects of antibiotics within biofilms or planktonic cell populations. Persister cells are of high clinical importance due to their tolerance to antimicrobial agents and subsequent failure in antibiotic treatments. Understanding persister cell formation mechanisms is therefore highly important for developing effective therapeutic strategies against pathogenic bacterial persisters. Several anti-persister compounds have been previously identified via isolation from natural resources or chemical synthesis. Furthermore, a combination of these compounds with antibiotics or non-antibiotic drugs also allows action on multiple targets while reducing the administration frequency. Here, we present a comprehensive overview of the clinical importance and formation mechanisms of persister cells as well as the current treatment strategies against persister cell formations in chronic infections.
Insights
Persister cells are dormant, antibiotic-tolerant bacteria that cause treatment failure. Understanding their formation and developing new strategies are crucial for combating chronic infections.
Area of Science:
- Microbiology
- Infectious Diseases
- Drug Discovery
Background:
- Persister cells are dormant, antibiotic-tolerant bacterial subpopulations.
- They contribute to treatment failure in chronic and biofilm infections.
- Their survival mechanisms pose a significant clinical challenge.
Purpose of the Study:
- To provide a comprehensive overview of persister cell biology.
- To discuss the clinical significance of persister cells.
- To review current and emerging therapeutic strategies against persister cells.
Main Methods:
- Literature review and synthesis of existing research on bacterial persisters.
- Analysis of mechanisms underlying persister cell formation and tolerance.
- Evaluation of identified anti-persister compounds and combination therapies.
Main Results:
- Persister cells are key to antibiotic tolerance and treatment non-response.
- Multiple compounds and combination strategies show promise against persisters.
- Targeting persister formation is a viable therapeutic approach.
Conclusions:
- Understanding persister cell formation is critical for developing effective treatments.
- Combination therapies and novel anti-persister agents offer new hope.
- Further research is needed to translate these findings into clinical practice.

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
