Disease Introduction MechanismCryptococcus neoformans, the predominant etiological agent of cryptococcosis, is an opportunistic fungal pathogen globally distributed throughout the environment. The primary route of infection is via inhalation of desiccated basidiospores or budding yeast. Cryptococcus can be cleared from the lungs, remain dormant in lung alveoli, or can disseminate to the central nervous system (CNS). Dissemination to the CNS, bones, or other tissues occurs in patients with severe deficiencies in CD4 T cell-mediated immunity, resulting in 15% of AIDS-related global deaths each year. However, Cryptococcus is also capable of affecting individuals with no obvious underlying im- munological deficiencies as demonstrated in the damage response framework by Pirofski and Casadevall. Therefore, effective clearance during the first encounter with the yeast is critical in preventing dissemination of the pathogen. We rely on resident pulmonary phagocytic cells, namely, macrophages and dendritic cells (DCs), to identify and effectively eradicate Cryptococcus.
