Aim:N-methyl-D-aspartate receptors(NMDAR)are heteromeric complexes pri-marily assembled from NR1 and NR2.*** normal conditions,NR2.sub-units assemble into homodimers in the endoplasmic reticulum(ER).Thesehomodimers remain in the ER until they coassemble with NR1 dimers and aretrafficked to the cell ***,it still remains unclear whether functionalhomomeric NMDAR exist in physiological or pathological ***:We transfected GFP-NR2. alone into HEK2.3 cells,treated the cells with PKCactivator 12.myristate-13 acetate(PMA),and then detected surface NR2. sub-units with a live cell immunostaining *** also used a series of NR2.mutants with a partial deletion of its C-terminus to identify the regions that areinvolved in the PMA-mediated surface expression of NR2. ***:NR2. subunits were expressed on the cell membrane after incubation with PMA(2.0 nmol/L,30 min),although no functional NMDA channels were detected afterPMA-induced membrane *** with an ER marker alsorevealed that NR2. subunits were exported from the ER after PMA ***,the deletion of amino acids between 1149-1347 or 1354-1464 ofNR2. inhibited PMA-induced surface expression ofNR2. ***:First,our data suggests that PMA treatment can induce the surface expression ofhomomeric NR2. ***,this process is probably mediated bythe NR2. C-terminal region between positions 1149 and 1464.

We report here a convective assembly process for the formation of large-area well-ordered closed-packed monolayers of polystyrene(PS) nanoparticles with different sizes on Si *** the large-area well-ordered non-closed packed monolayer of PS nanoparticles were obtained using an asher etching machine,the reactive gas O was used to minify the close-packed polystyrene *** coatings of large-area well-ordered non-closed-packed monolayers of PS nanoparticles are characterized with scanning electron *** results indicate that the size of PS nanoparticles and distance between particles can be controlled by etching *** rapid large-area well-ordered closed-packed/non-closed-packed monolayer with PS nanoparticles provided a glimpse at the wide range of coating and photonic device applications where convective assembly and etching can be used.
