Abstract
Organoid cultures may express several types of pattern-recognition receptors and in particular toll-like receptors, representing an extremely efficient and innovative system to understand how pathogen-associated molecular patterns exposure may affect the immunity, the growth, or differentiation of complex tissues. Here, we describe how to generate lung organoids from human-induced pluripotent stem cells. Three-dimensional (3D) cultures are then stimulated with different toll-like receptor ligands derived from fungi or with Aspergillus fumigatus. RNA sequencing may be performed upon organoid cultures to understand host-pathogen innate immune interactions.
