When an Arabidopsis leaf is exposed to bacteria on the leaf surface, or to the MAMP flg22, the stomatal apertures closed by LRR receptor-like kinase FLS2, as well as a heterotrimeric G protein.

T-independent response

Type 1 T-independent (TI-1) antigens bind to B cells through both Ig and innate immune receptors. LPS from Gram negative organisms binds to B cells via both mIg and TLR, resulting in signaling from both receptors.

Class I MHC, glycoproteins expressed on the surface of nearly all nucleated cells; the major function of the class I is presentation of endogenous peptide antigens to CD8+ T cells.
