Molecular analyses showed that CO23RFLC had acquired a marked increased expression of the MDR1 gene encoding for an efflux pump protein mainly responsible for the drug-resistance, due to a mutation in the transcription factor gene MRR1 [16] whereas CO23RFK had a homozygous mutation (S645Y substitution) in the FSK1 gene, responsible for the synthesis of glucan [17]
Simultaneously, catalytically produced hydrogen peroxide (H 2 O 2 ) activates the protein transient receptor potential melastatin 2 (TRPM2) ion channel, promotes calcium influx, activates macrophages, and induces systemic immune response (Fig
