TLR1 and aspergillosis: In addition, polymorphisms within immune receptors have been identified as secondary contributors such as Dectin-1 Y238X with aspergillosis in transplant patients [108] and TLR1 polymorphisms in candidemia [109] as well as an association of aspergillosis in transplants [110] with defects in signaling pathways related to these receptors including Dectin-1-related CARD9 [111].
