In addition to PKA-mediated signaling, activated AC may also activate mitogen activated protein kinase (MAPK) pathway through exchange protein activated by adenylyl cyclase (EPAC).
Parasite antigens may also activate p38 mitogen-activated protein kinase P [33], which has been reported to mediate IL-4-induced expression of CD23 [29].
However, we do not discount the possibility that in vivo other proteases downstream of MMP-8 activity may also activate LIX.
Insulin signaling may also activate the mitogen activated protein kinase (MAPK) isoforms ERK1 and ERK2, through Grb/Sos and ras.
While HMGB1 alone can display cytokine activity, it may also activate cells in conjunction with other immune stimulators such as TLR ligands.
Thus, activation of P2X7R may also activate different intracellular signaling mechanisms to regulate distinct cellular functions in various types of cells.
Thus, it is a potent activator of Th1 cells but, in context, may also activate Th2 cells, NK cells, and natural killer T (NKT) cells.
Increased SHC and Rho (RHOB) expression may also activate Cdc42, a key cell cycle regulator, and contribute to PI3K/Akt activation.
IL-1β has been considered to be an activator of ILC3s, but a recent study demonstrated that IL-1β may also activate ILC2s (Bal et al., 2016).
RONS may also activate CaMKKβ by direct modification of RONS sensitive motifs and, indirectly, by activating the ryanodine receptor (Ryr) to release Ca2+.
While Mr. Lieberman may also activate the Orthodox vote that is heavily conservative, Mrs. Clinton seems confident that she will make a net gain from his presence on the New York ballot.
