Not only small organic molecules but also polymers containing two initiation functions, further referred to as macro dual initiators, which can initiate different polymerizations independently and selectively, are described.
In this way, the MS can initiate different "scanning behaviors" according to the measurements received.
Upon ligand binding, NLRs multimerize and initiate different signaling cascades.
Moreover, it is thought they may use distinct downstream signaling pathways and initiate different biological outcomes.
These proapoptotic proteins may initiate different apoptotic signaling causing demise of cancer cells.
The oncogenic stimulations of these pathways initiate different types of tumours (Dumont et al, 1989, 2005; Williams, 1994; Fagin, 2002; Fusco et al, 2002).
Patients are allowed to contribute multiple sets of observations if they initiate different biologics over the study period; if they do so, a new 'baseline' visit is established.
Another possibility is that ER and PR initiate different signal transduction pathways and the activation of the ER pathway induces ER production.
Its initial function is to promote expression of downstream genes such as ASCL1, DLX2 and OLIG2-factors that initiate different aspects of LGE/CGE identity [ 35].
The selectin ligands P-selectin glycoprotein ligand 1 (PSGL-1), E-selectin ligand 1 (ESL-1), and CD44 initiate different intracellular signalling pathways in neutrophils.
Bacterial infections initiate different responses from the immune system compared with viruses but gram-negative and gram-positive bacteria are both capable of activating the innate immune system (Takeuchi et al., 1999; Yoshimura et al., 1999).
