Vomocytosis of Cryptococcus neoformans cells from murine, bone marrow-derived dendritic cells.

ABSTRACT: Cryptococcus neoformans (CN) cells survive within the acidic phagolysosome of macrophages (MΦ) for extended times, then escape without impacting the viability of the host cell via a phenomenon that has been coined 'vomocytosis'. Through this mechanism, CN disseminate throughout the body, sometimes resulting in a potentially fatal condition-Cryptococcal Meningitis (CM). Justifiably, vomocytosis studies have focused primarily on MΦ, as alveolar MΦ within the lung act as first responders that ultimately expel this fungal pathogen. Herein, we hypothesize that dendritic cells (DCs), an innate immune cell with attributes that include phagocytosis and antigen presentation, can also act as 'vomocytes'. Presciently, this report shows that vomocytosis of CN indeed occurs from murine, bone marrow-der
