The homeobox transcription factor Pitx3 is similarly and selectively expressed in the same neurons. Pitx3 deficiency in a natural mouse mutant, the <jats:italic>aphakia<\/jats:italic> mouse, was correlated with the loss of these neurons and with a deficit in locomotor activity. We now report that the locomotor deficit of <jats:italic>aphakia<\/jats:italic> mice is established by 40\u2003days of age and that it can be rescued by injection of <jats:sc>l<\/jats:sc>\u2010dopa. We further show that downstream striatal correlates of the midbrain neuronal losses in <jats:italic>aphakia<\/jats:italic> mice, as assessed by dopamine transporter binding and expression of dopamine receptors, enkephalin, dynorphin and neurotensin, are highly similar to neuroadaptive responses observed following rapid neurodegeneration induced by neurotoxin administration in adult animals or following the progressive neurodegenerative processes as seen in Parkinson patients. Taken collectively, these data support the idea that the <jats:italic>aphakia<\/jats:italic> mice represent a selective model of dopaminergic deficiency that closely resembles the midbrain and striatal neuropathology associated with Parkinson's disease, and this suggests that these mice are a good model to assess therapies for Parkinson's disease as well as to understand the susceptibility of these neurons to neurodegeneration.<\/jats:p>","DOI":"10.1111\/j.1471-4159.2005.03522.x","type":"journal-article","created":{"date-parts":[[2005,11,3]],"date-time":"2005-11-03T12:12:29Z","timestamp":1131019949000},"page":"160-170","source":"Crossref","is-referenced-by-count":50,"title":["Striatal neuroadaptation and rescue of locomotor deficit by <scp>l<\/scp>\u2010dopa in <i>aphakia<\/i> mice, a model of Parkinson's disease"],"prefix":"10.1111","volume":"96","author":[{"given":"Pepijn","family":"Van Den Munckhof","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fran\u00e7ois","family":"Gilbert","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michel","family":"Chamberland","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"L\u00e9vesque","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jacques","family":"Drouin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2005,11,8]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.bbr.2003.12.021"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1471-4159.2000.0751694.x"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1136\/jmg.2004.020289"},{"key":"e_1_2_7_5_1","first-page":"779","article-title":"Selective labeling of the dopamine transporter by the high affinity ligand 3\u03b2\u2010(4\u2010[125I]iodophenyl) tropane\u20102 \u03b2\u2010carboxylic acid isopropyl ester","volume":"47","author":"Boja J.
