Among the studied fungal infections, TLR9 activation was related to DNA from A. fumigattus, C. albicans, P. brasiliensis, S. cerevise, M. furfur, and C. neoformans (Nakamura et al., 2008; Ramirez-Ortiz et al., 2008; Kasperkovitz et al., 2010, 2011; Menino et al., 2013). Here, TLR9 is linked to fungal infectious disease.
