Resumen

• The study of transcriptomics in trypanosomatids is essential for understanding their unique gene expression mechanisms, which are predominantly regulated post-transcriptionally due to polycistronic transcription and a lack of specific promoters. These parasites, responsible for diseases such as Chagas disease and leishmaniasis, pose significant global health challenges. To improve transcriptomic data analysis, a structured bioinformatics workflow has been developed. This method integrates various tools to efficiently process RNA sequencing data. The workflow begins with raw data preprocessing, including sequence cleaning and filtering. Differential expression analysis is then performed to identify genes with altered activity under different conditions. Functional annotation follows, utilizing databases such as Gene Ontology (GO) and KEGG Orthology (KO) to assign gene functions. Finally, data visualization techniques are applied to present findings clearly. This approach accounts for the complexity of trypanosomatid transcriptomes, optimizing research by providing a standardized framework. It enables precise gene expression profiling, facilitating insights into parasite survival, adaptation, immune evasion, and drug resistance. The methodology is also applicable to other parasites and fields like molecular epidemiology and targeted therapy development, making it a crucial tool for advancing research and treatment strategies against these pathogens.
