5.    Which of the following statements is true(1)    After sensing flagella, pattern recognition receptor TLR5 can activate downstream immune signaling pathway through MyD88. (2)    In mammalian cells, flagellin can be recognized by Toll-like receptors such as TLR5 on the membrane and cytosolic PRRs such as NAIP5 or NAIP6. On the other hand, in plant cells, flagellin can be recognized by membrane localized PRRs such as FLS2.   (3)    Flagellin can not trigger MyD88-independent pathway in mammalian cells.
