Cell wall preparation of S. cerevisiae

Zymosan, an insoluble preparation of cell wall from Saccharomyces cerevisiae, activates macrophages via TLR2.

TLR2 cooperates with TLR6 and CD14 in response to zymosan [1].

Zymosan is also recognized by Dectin-1, a phagocytic receptor expressed on macrophages and dendritic cells, which collaborates with TLR2 and TLR6 enhancing the immune responses triggered by the recognition of Zymosan by each receptor [2].
