New Systems for Studying Intercellular Interactions in Bacterial Vaginosis.

Area of Science:

• Microbiology
• Reproductive Health
• Infectious Diseases

Background:

• Bacterial vaginosis (BV) impacts nearly a quarter of US women, posing significant public health challenges.
• Fundamental questions persist regarding BV etiology, its link to adverse reproductive outcomes, and high treatment failure rates.
• Existing model systems face limitations in fully recapitulating the complex vaginal microenvironment.

Purpose of the Study:

• To review the strengths and limitations of current in vitro and in vivo model systems for studying bacterial vaginosis (BV).
• To discuss necessary advancements for enhancing the translational utility of these models.
• To highlight the need for integrated approaches to address remaining questions about BV.

Main Methods:

• Review of existing literature on in vitro and in vivo model systems for studying bacterial vaginosis.
• Analysis of the capabilities and shortcomings of various model systems in simulating the human vaginal microenvironment.
• Discussion of future directions and required advancements for model system development.

Main Results:

• Both in vitro and in vivo models offer valuable insights but have inherent limitations in replicating the complexity of the vaginal microbiome.
• No single model system can fully capture the intricate host-microbe and microbe-microbe interactions in BV.
• Significant advancements are needed to improve the physiological relevance and predictive power of current models.

Conclusions:
