Diagnosis is challenging, immunodiagnosis tests are commonly implemented with major pitfalls in the cross-reactivity with other pathogens, particularly in endemic areas.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods<\/jats:title>\n            <jats:p>With the aim of identify species-specific genes encoding for highly expressed antigenic proteins, a list of parasites that may infect humans and that might present similar clinical symptoms to <jats:italic>T. canis<\/jats:italic> infections was built. Only organisms whose genomes were completely sequenced and the proteome predicted were included. First, orthologous proteins were detected and the subcellular localization of <jats:italic>T. canis<\/jats:italic> proteins was predicted. In order to identify differentially expressed genes encoding proteins in larvae L3, pair-wise comparisons among transcriptomes from body parts and genders were performed. Finally, all secreted proteins classified as species-specific of <jats:italic>T. canis<\/jats:italic>, whose genes were upregulated in larvae L3 were included in an antigenic prediction.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>Twenty-eight parasites were included in the analyses, proteins of <jats:italic>T. canis<\/jats:italic> were clustered in 11,399 groups, however, 279 were species-specific groups which represent 816 proteins. Three hundred and twenty-two proteins were predicted to be secreted and upregulated in larvae L3, however, after filtering these proteins by their orthology inference, only three proteins met all the features included in this study (species-specific, upregulated, secreted, and antigenic potential). To conclude, our strategy in the study is a rational approach for discovering antigenic proteins to be used in diagnosis.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1007\/s11686-024-00966-0","type":"journal-article","created":{"date-parts":[[2025,2,7]],"date-time":"2025-02-07T14:23:06Z","timestamp":1738938186000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["In Silico Discovery of Antigenic-Secreted Proteins to Diagnostic Human Toxocariasis"],"prefix":"10.1007","volume":"70","author":[{"given":"Mar\u00eda A.","family":"Henao","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isabella","family":"Cortes","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan P.","family":"Isaza","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2025,2,7]]},"reference":[{"key":"966_CR1","doi-asserted-by":"publisher","unstructured":"Despommier D (Apr. 2003) Toxocariasis: clinical aspects, epidemiology, medical ecology, and molecular aspects.
