Neutrophils are essential for aspergillosis resistance, as demonstrated in neutropenic individuals, and are capable of sequestering both conidia and hyphae through distinct, non-phagocytic mechanisms.
Studies suggest that the endolymphatic duct and endolymphatic sac perform both absorptive and secretory, as well as phagocytic and immunodefensive, functions.
These early-invading, phagocytic macrophages reach their highest concentration about 24 hours following the onset of some form of muscle cell injury or reloading.
