Candidalysindiscovery and function in candida albicans infections Candidalysin: The Fungal Peptide Toxin Critical for Mucosal Infection
Candidalysin is a potent fungal peptide toxin that plays a critical role in mucosal infections, particularly those caused by the opportunistic pathogen *Candida albicans*.作者：LIN JIANFENG—Candidalysin is a fungal peptide toxin critical for mucosal infection. Nature 532, 64-68, doi:10.1038/nature17625 (2016). 4 Russell, C. M. ... This secreted toxin is a key virulence factor, directly contributing to the damage of host epithelial tissues and triggering significant immune responses. Its discovery has shed light on the complex mechanisms by which *C. albicans* establishes and perpetuates infections, highlighting its importance in both mucosal and systemic diseaseThis peptide toxin is secreted by Candida hyphae and it is a critical factor for the activation of epithelialimmuneresponses (at a lower dose) and for the ....
As a cytolytic peptide toxin, candidalysin's primary function is to disrupt host cell membranesCandidalysin is a fungal peptide toxin critical for mucosal .... It achieves this by forming pores, which leads to direct cellular damage. This membrane damage is not merely destructive; it serves as a critical step in *C作者：JP Richardson·2022·被引用次数：67—Candidalysin is critical for C. albicans mucosal infectionsand is produced by targeted proteolytic processing of the hypha-associated protein .... albicans*'s pathogenic strategy. The disruption of epithelial barriers not only facilitates the invasion of the fungus but also initiates a cascade of host responses.Candidalysin
Candidalysin triggers a danger signaling pathway, activating epithelial immunity.Candidalysin is a fungal peptide toxin critical for mucosal ... This activation involves the release of inflammatory mediators and the recruitment of immune cells, such as neutrophils. While these responses are part of the host's defense, the damage inflicted by candidalysin can also overwhelm and dysregulate these immune processes, paradoxically aiding the fungal infection. The toxin's ability to induce inflammation, neutrophil recruitment, and Type 17 immunity underscores its central role in the pathobiology of *CCandidalysin is a fungal peptide toxin critical for mucosal .... albicans* infections.
The identification of candidalysin marked a significant advancement in understanding fungal pathogenesis. It is recognized as the first identified fungal cytolytic peptide toxin in *Candida albicans*. This peptide toxin is derived from the hypha-associated protein Ece1 through proteolytic processing. Its critical role in mucosal infections, including vaginal candidiasis, has been extensively studied.Candidalysin Is Required for Neutrophil Recruitment and ...
The research surrounding candidalysin has revealed its dual function: it damages immune cell membranes, potentially aiding the fungus's escape, while simultaneously activating immune responses. This complex interplay highlights the sophisticated strategies employed by *CCandidalysin is a fungal peptide toxin critical for mucosal .... albicans* to overcome host defenses. The toxin's activity is crucial for the establishment of both mucosal and systemic infections, making it a prime target for understanding and potentially treating these conditions.
Candidalysin's impact extends to its interaction with the host's immune systemCandidalysinis a cytolytic 31-amino acid α-helical amphipathic peptide toxin secreted by the opportunistic pathogen Candida albicans.. It is known to activate epithelial cells, leading to downstream innate immune responses作者：DL Moyes·2016·被引用次数：1085—This secretedtoxindirectly damages epithelial membranes, triggers a danger response signalling pathway and activates epithelial immunity.. This activation is essential for initiating an inflammatory defense against the fungal pathogen. Specifically, candidalysin has been shown to be a key driver of host cell activation, neutrophil recruitment, and the development of Type 17 immunity, which is critical for combating fungal infectionsCandidalysin.
Furthermore, candidalysin stimulates signaling pathways like EGFR and various MAPKs, contributing to the inflammatory milieu. It also activates the NLRP3 inflammasome, promoting inflammatory responses作者：SA Nikou·2022·被引用次数：63—Candidalysin, a toxin secreted by the opportunistic fungal pathogen Candida albicans, induces inflammation by stimulating EGFR signaling and several MAPK .... While these immune activations are designed to clear the infection, the damage caused by candidalysin can lead to an exaggerated or dysregulated immune reaction, contributing to the pathology of the infectionCandidalysin is a fungal peptide toxin critical for mucosal .... Understanding these interactions is vital for developing therapeutic strategies that modulate the host response effectively.
The critical role of candidalysin in fungal pathogenesis makes it an attractive target for therapeutic intervention.The fungal peptide toxin candidalysin induces distinct ... Research into candidalysin treatments aims to neutralize its toxic effects or inhibit its productionCandidalysin: discovery and function in Candida albicans .... Understanding the specific mechanisms by which candidalysin interacts with host cells and triggers immune responses can pave the way for novel antifungal therapies. By targeting this key virulence factor, it may be possible to disarm *Candida albicans* and prevent the establishment and progression of infections, particularly in immunocompromised individuals who are highly susceptible to *C. albicans* related diseases. Further research into the candidalysin sequence and its structure may also offer insights into developing peptide-based inhibitors or vaccines...Candidalysin is essential for mucosal and systemic infections, activating NLRP3 to promote inflammatory responses, neutrophil recruitment, and Th17 immunity ....
