To illustrate how the introduced localized diffusion barriers act, in Fig. 2, we show [ADP] concentrations at steady state after addition of 0.3 mM of ADP to the external solution.
Therefore, attempted Pst infection of broad bean resulted in rapid production and accumulation of H2O2 (but not O2-) and callose deposition, presumably related to the generation of subcellular, localized physical barriers.
On the contrary, at low frequencies and electric DC-conditions, the walls of potential barriers localized will stop charges against their walls.
The mechanism of the BSF related PL is suggested to be an indirect exciton transitions due to the recombination of electrons confined in the ZB QWs to holes in the WZ barriers localized near the BSFs.
Moreover, Ist2p is retained in the plasma membrane domain of the daughter cell by a septin barrier localized at the bud neck blocking lateral diffusion of Ist2p back to the mother cell membrane domain [ 16].
These results, together with our finding that MMP13+ staining appears localized with the "barrier-like" Collagen I fibers around the tumor periphery in the TACS-2 (WT) condition (Additional file 2: Figure S2), all suggest that MMP13 in particular may be a principal contributor to TACS phenotype.
Manganese exposure alters iron homeostasis in blood and cerebrospinal fluid (CSF), possibly by acting on iron transport mechanisms localized at the blood brain barrier and/or blood CSF barrier.
It has also been found to be predominantly localized to blood-tissue barriers, such as the basolateral membrane of the choroid plexus cells of the blood-cerebrospinal fluid barrier, the bronchial epithelium [20], [21], and the apical syncytiotrophoblast membrane of the placenta [22].
ADR is 500 3000 times more effective against glioma cells in vitro [88] than in vivo, but the presence of efflux pumps localized at the blood brain barrier renders it ineffective against tumors in the CNS [12], [89].
