The importance of the calcineurin pathway in fungal physiology creates an opportunity for the development of new antifungal therapies that target this critical signaling pathway. In this study, we examined the role of the zinc finger transcription factor Crz1 homolog (CrzA) in the physiology and pathogenicity of the opportunistic human fungal pathogen\n            <jats:italic>Aspergillus fumigatus<\/jats:italic>\n            . Genetic replacement of the\n            <jats:italic>crzA<\/jats:italic>\n            locus in\n            <jats:italic>A. fumigatus<\/jats:italic>\n            resulted in a strain with significant defects in conidial germination, polarized hyphal growth, cell wall structure, and asexual development that are similar to but with differences from defects seen in the\n            <jats:italic>A. fumigatus<\/jats:italic>\n            \u0394\n            <jats:italic>cnaA<\/jats:italic>\n            (calcineurin A) strain. Like the \u0394\n            <jats:italic>cnaA<\/jats:italic>\n            strain, the \u0394\n            <jats:italic>crzA<\/jats:italic>\n            strain was incapable of causing disease in an experimental persistently neutropenic inhalational murine model of invasive pulmonary aspergillosis. Our results suggest that CrzA is an important downstream effector of calcineurin that controls morphology in\n            <jats:italic>A. fumigatus<\/jats:italic>\n            , but additional downstream effectors that mediate calcineurin signal transduction are likely present in this opportunistic fungal pathogen. In addition, the importance of CrzA to the production of disease is critical, and thus CrzA is an attractive fungus-specific antifungal target for the treatment of invasive aspergillosis.\n          <\/jats:p>","DOI":"10.1128\/ec.00086-08","type":"journal-article","created":{"date-parts":[[2008,5,4]],"date-time":"2008-05-04T01:46:21Z","timestamp":1209865581000},"page":"1085-1097","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":164,"title":["Calcineurin Target CrzA Regulates Conidial Germination, Hyphal Growth, and Pathogenesis of\n            <i>Aspergillus fumigatus<\/i>"],"prefix":"10.1128","volume":"7","author":[{"suffix":"Jr.","given":"Robert A.","family":"Cramer","sequence":"first","affiliation":[{"name":"Department of Molecular Genetics and Microbiology, Duke University Medical Center, Durham, North Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B.
