The lacking immune response toward C. albicans antigen but not toward HKLM, which can both act as TLR2 agonists (21, 52, 53), or toward LPS or A. fumigatus adds to the notion of preserved immune function in COV, and is inconsistent with results indicating a generally attenuated TLR response of the peripheral innate immune system from COVID-19 patients (54). Here, TLR2 is linked to COVID-19.
