Extending the analysis of nicotinic receptor antagonists with the study of α6 nicotinic receptor subunit chimeras

Extending the analysis of nicotinic receptor antagonists with the study of alpha6 nicotinic receptor subunit chimeras.

Heterologous expression systems have increased the feasibility of developing selective ligands to target nicotinic acetylcholine receptor (nAChR) subtypes. However, the alpha6 subunit, a component in nAChRs that mediates some of the reinforcing effects of nicotine, is not easily expressed in systems such as the Xenopus oocyte. Certain aspects of alpha6-containing receptor pharmacology have been...

Mutational analysis of muscle nicotinic acetylcholine receptor subunit assembly

The structural elements required for normal maturation and assembly of the nicotinic acetylcholine receptor alpha subunit were investigated by expression of mutated subunits in transfected fibroblasts. Normally, the wild-type alpha subunit acquires high affinity alpha bungarotoxin binding in a time-dependent manner; however, mutation of the 128 and/or 142 cysteines to either serine or alanine, ...

the analysis of the role of the speech acts theory in translating and dubbing hollywood films

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...

lmmunocytochemical Localization of a Neuronal Nicotinic Receptor: The @2=Subunit

We have characterized in adult rat the tissue-specific expression of the nicotinic ACh receptor (AChR) @S-subunit using antisera raised against fusion protein constructs. Immunohistochemical localization revealed immunoreactivity distributed throughout the neuraxis. Overall, @2-like immunoreactivity (@2-LI) correlated well with in situ localization of 82 transcript in neuronal cell bodies. Part...
