ALS is characterized by an extensive loss of motoneurons in the cerebrospinal axis, except for those motoneurons that control eye movements and bladder contraction. The reason for this selectivity is not known. Systematic differences have been found in the organization of excitatory synaptic transmission in ALS\u2010resistant vs. ALS\u2010susceptible motor nuclei. However, although motoneurons express high levels of glycine receptors (GlyR) and GABA<jats:sub>A<\/jats:sub> receptors (GABA<jats:sub>A<\/jats:sub>R), no such studies have been carried out yet for inhibitory synaptic transmission. In this study, we compared the subunit composition, patterns of expression, density and synaptic localization of inhibitory synaptic receptors in ALS\u2010resistant (oculomotor, trochlear and abducens) and ALS\u2010vulnerable motoneurons (trigeminal, facial and hypoglossi). Triple immunofluorescent stainings of the major GABA<jats:sub>A<\/jats:sub>R subunits (\u03b11, \u03b12, \u03b13, and \u03b15), the GlyR \u03b11 subunit and gephyrin, were visualized by confocal microscopy and analysed quantitatively. A strong correlation was observed between the vulnerability of motoneurons and the subunit composition of GABA<jats:sub>A<\/jats:sub>R, the GlyR\/GABA<jats:sub>A<\/jats:sub>R density ratios and the incidence of synaptic vs. extrasynaptic GABA<jats:sub>A<\/jats:sub>R. These differences contrast strikingly with the uniform gephyrin cluster density and synaptic GlyR levels recorded in all motor nuclei examined. These results suggest that the specific patterns of inhibitory receptor organization observed might reflect functional differences that are relevant to the physiopathology of ALS.<\/jats:p>","DOI":"10.1111\/j.1460-9568.2006.04863.x","type":"journal-article","created":{"date-parts":[[2006,6,19]],"date-time":"2006-06-19T13:41:31Z","timestamp":1150724491000},"page":"3161-3170","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":58,"title":["Differential expression of GABA<sub>A<\/sub> and glycine receptors in ALS\u2010resistant vs. ALS\u2010vulnerable motoneurons: possible implications for selective vulnerability of motoneurons"],"prefix":"10.1111","volume":"23","author":[{"given":"Louis\u2010Etienne","family":"Lorenzo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Annick","family":"Barbe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paule","family":"Portalier","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean\u2010Marc","family":"Fritschy","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H\u00e9l\u00e8ne","family":"Bras","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2006,6,19]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s004150200071"},{"key":"e_1_2_7_3_1","first-page":"428.21","article-title":"Differential inhibitory synaptic transmission in ALS\u2010resistant versus ALS\u2010vulnerable motoneurons","author":"Bras H.","year":"2005","journal-title":"Soc.
