Proteome profiling of Candida albicans

The complex ecological dynamics between Streptococcus mutans and Candida albicans within dental plaque biofilms play a pivotal role in the etiology of dental caries. To investigate the "contact-independent" interactions between these two species, we developed a transwell co-culture system. Utilizing quantitative proteomics profiling, we aimed to dissect the impact of S. mutans on the proteomics profile of C. albicans and to uncover the molecular mechanisms that regulate their interaction. These results underscore the profound changes in the proteomics landscape of C. albicans in response to co-cultivation with S. mutans. Our study offers novel insights into the functional interplay between these predominant constituents of dental plaque, shedding light on their role in oral microbial ecology and the pathogenesis of dental caries.
