Likewise, in human olfactory mucosa, collections of neurites have been noted in a variety of disease states, including Alzheimer's disease. We report here an immunohistochemical and electron microscopic analysis of aberrant axonal growth in the rat olfactory mucosa induced by experimental lesion. In particular, we have used the monoclonal antibody 2G12, which binds to the phosphorylated form of GAP\u201043, as an extremely sensitive marker for neuromatous axons, because it does not label neuronal cell bodies. In unilaterally bulbectomized rats, neuromas form in posterior olfactory epithelium on the operated side. Several lines of evidence, including serial section reconstruction, indicate that olfactory axons are induced to grow back into the epithelium at a distance from their point of origin as a consequence of bulbectomy, and are accompanied by glial cells from the olfactory nerve. Avulsion of a part of the olfactory nerve has similar effects as destruction of the olfactory bulb. Intraepithelial neuromas also develop in the olfactory mucosa of rats simultaneously exposed to methyl bromide gas and injected with 3\u2010methyl indole; this treatment severely damages the olfactory epithelium directly. Exposure to methyl bromide alone causes milder damage, and the neuromas that form are transient. The evidence indicates that neuromas form after the epithelium is directly damaged because axons are trapped in the epithelium. Both of the mechanisms identified here should be taken into account when considering the findings in the human olfactory mucosa. \u00a9 Wiley\u2010Liss, Inc.<\/jats:p>","DOI":"10.1002\/cne.903400307","type":"journal-article","created":{"date-parts":[[2005,1,1]],"date-time":"2005-01-01T09:16:24Z","timestamp":1104570984000},"page":"361-380","source":"Crossref","is-referenced-by-count":37,"title":["On the formation of neuromata in the primtary olfactory projection"],"prefix":"10.1002","volume":"340","author":[{"given":"James E.","family":"Schwob","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steven L.","family":"Youngentob","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karina F.","family":"Meiri","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2004,10,9]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/0306-4522(82)90231-7"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/0896-6273(91)90245-U"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/0014-4886(92)90221-B"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/cne.902150403"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1460-9568.1991.tb00099.x"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/cne.901660105"},{"key":"e_1_2_1_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/cne.902940212"},{"key":"e_1_2_1_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/aja.1001210107"},{"key":"e_1_2_1_10_1","first-page":"191","volume-title":"Essays on Structure and Function in the Nervous System","author":"Graziadei P.
