Three gene lists compiled from the GeneCards database using keywords were characterized by analyses of overlap, protein\u2013protein interaction (PPI) networks, and by protein-enrichment analysis. Key proteins were selected on the basis of the degree and combined score value of the corresponding PPI network. In the NH process, BDNF, CASP3, and PVALB were identified as high-degree proteins (HDPs). In the AS process, BDNF, PVALB, and DLG4 are the top three HDPs; in the Tin process, these are BDNF, APP, and TNF. In the Tin process, key proteins appear that differ pre- and postsynaptically from those detectable in NH or AS. The glucocorticoid receptor NR3C1 and its interaction with FKBP5, a glucocorticoid receptor-induced co-chaperone, appear to be of particular importance for the emotional aspects of tinnitus. In tinnitus, the HDPs, together with their high-score interaction proteins, indicate processes of chronic neurodegeneration and of changes in transcription, intercellular communication, and in the survival and growth of neurons.<\/jats:p>","DOI":"10.3390\/ijms27041854","type":"journal-article","created":{"date-parts":[[2026,2,16]],"date-time":"2026-02-16T10:14:32Z","timestamp":1771236872000},"page":"1854","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Candidate Key Proteins in Thalamo-Amygdala Signaling in Tinnitus: A Bioinformatics Study"],"prefix":"10.3390","volume":"27","author":[{"given":"Johann","family":"Gross","sequence":"first","affiliation":[{"name":"Tinnitus Center, Charit\u00e9-Universit\u00e4tsmedizin Berlin, 10117 Berlin, Germany"},{"name":"Leibniz Society of Science Berlin, 10117 Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marlies","family":"Knipper","sequence":"additional","affiliation":[{"name":"Leibniz Society of Science Berlin, 10117 Berlin, Germany"},{"name":"Department of Otolaryngology, Head and Neck Surgery, T\u00fcbingen Hearing Research Center (THRC), Molecular Physiology of Hearing, University of T\u00fcbingen, 72076 T\u00fcbingen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9587-6632","authenticated-orcid":false,"given":"Birgit","family":"Mazurek","sequence":"additional","affiliation":[{"name":"Tinnitus Center, Charit\u00e9-Universit\u00e4tsmedizin Berlin, 10117 Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1600","DOI":"10.1016\/S0140-6736(13)60142-7","article-title":"Tinnitus","volume":"382","author":"Baguley","year":"2013","journal-title":"Lancet Lond.
