    Infect Immun 75:4769-79. 2007
    ..Interestingly, treatment of wild-type cells with caspofungin also increased MBL binding to C. neoformans. These results suggest that both the presence of capsule and wild-type cell wall architecture preclude MBL binding to C. neoformans...

    Mol Microbiol 62:1090-101. 2006

    Mol Microbiol 61:1132-46. 2006
