Metabolite Identification
Common NameGranadaene
DescriptionGranadaene is a cytotoxic lipid toxin classified as a metabolite, primarily associated with Group B Streptococcus (GBS). It exhibits cytotoxic effects on various immune cells, including T and B cells, highlighting its potential role in immune evasion during infections (PMID:37384812 ). The presence of granadaene in GBS strains, such as COH1 and NCTC, suggests its involvement in the pathogenesis of GBS diseases, particularly through its relationship with hemolysin/cytolysin (PMID:33502005 ). Interestingly, granadaene also has photophysical properties, acting as an endogenous chromophore that absorbs blue light, which can influence the susceptibility of GBS to antimicrobial treatments (PMID:33578336 ). Recent studies have identified edible insects as a potential reservoir for granadaene-producing lactococci, raising concerns about zoonotic risks associated with these bacteria (PMID:35615513 ). Furthermore, the use of synthetic analogs of granadaene, such as R-P4, has shown promise in reducing bacterial dissemination during systemic infections, indicating a potential therapeutic avenue (PMID:37384812 ). Overall, granadaene represents a significant factor in the virulence and pathogenicity of GBS, with implications for both microbiology and immunology.
