Posted by Interestingly fungal quorum sensing signal molecules (QSMs) were found effective against bacterial biofilms hindering the healing of chronic non-healing wounds such as diabetic foot ulcers, surgical site infections, pressure ulcers, and venous leg ulcers.
Chronic non-healing wounds have emerged as a significant global healthcare challenge. Biofilm induced wound infections has been widely acknowledged. Despite the advanced understanding of biofilm formation, the existing approaches for diagnosing biofilms in wounds remain considerably suboptimal. Chemical signals produced by fungi to sense their environment, known as quorum sensing (QS) molecules (QSM) such as farnesol and tyrosol are identified as potential therapeutic agents for wound management,
Biofilms render chronic wounds resistant to treatment and impede tissue repair by inducing chronic inflammation. QS is a biochemical signaling pathway that involves certain secreted molecules, namely phenylethanoids, indolyl, and sesquiterpene alcohols, such as tyrosol that can significantly minimize and obliterate bacterial biofilms if properly applied and released in wound treatments. QS molecules (QSMs) possess inhibitory properties that obstruct the formation of microbial biofilms and exhibit synergism with common antimicrobials. They can disrupt biofilms formed by drug-resistant microorganisms. The understanding of the current mechanisms and advancements in the utilization of QSMs within diverse drug delivery systems, including cyclodextrin complexation and their release dynamics will be crucial in new drug design and delivery. Exploration of co-delivery of drugs alongside QS molecules, and assessing their impact on healing of chronic wounds before moving to clinical trials remain unaddressed.
