| dc.description.abstract1 | Cryptococcus neoformans was first isolated from a patient in 1894 [1] and 130 years later, it
remains a prevalent global threat, especially for people living with human immunodeficiency
virus (HIV) [2]. Human–Cryptococcus interaction begins in childhood, after inhalation of
basidiospores which are widespread in the environment. Typically, this interaction advances
in one of the 4 major possible ways: (I) latent/dormant (asymptomatic) cryptococcosis, where
C. neoformans can hide in the host for years without any clinical symptoms; (II) pulmonary
cryptococcosis (cryptococcal pneumonia), which may or may not need medical intervention
depending on host’s underlying conditions; (III) disseminated cryptococcosis, where C. neoformans probably disseminates from lungs to different organs such as kidneys, bones, skin,
and to the central nervous system by crossing the blood–brain barrier, after reactivation from
dormancy; (IV) cryptococcal relapse, where the formerly treated infection resurfaces and
requires specific medical management. Population heterogeneity (also referred to as phenotypic heterogeneity) provides a functional advantage to many microbial pathogens to survive
in fluctuating conditions (please refer to this excellent review [3]). It can be defined as the preexisting diversity within an isogenic population. Population heterogeneity arises due to the
phenotypic differences between individual cells in an otherwise genetically identical/homogenous population. Prominent examples of phenotypic heterogeneity (well known in bacteria
but not much in fungi) are biofilm, antimicrobial persistence, heteroresistance, and cellular
dormancy, which is often observed as a viable but nonculturable (VBNC) phenotype. As
described further in the review, population heterogeneity provides benefits to the C. neoformans population in coping with unpredictable environmental and host conditions. It contributes to the survival of C. neoformans in challenging and ever-changing conditions such as
switching from the outer atmosphere to the host lungs, from extracellular to intracellular
niche (e.g., inside macrophages), from lungs to brain or other tissues, from compromised
immune system to exposure to antifungal drugs. | pt_BR |
