To establish an infection, this fungus coordinates many mechanisms related to biochemical processes, physiological adaptation, and transcriptional networks. Transcription factors (TFs) are the main proteins that elicit biological responses when T. rubrum interacts with keratinized tissues and promotes defense responses to prevent fungal colonization. In this study, we investigated the role of the TF StuA, a recently described T. rubrum protein, in controlling this fungal transcriptional program in response to glucose and keratin. This approach, based on RNA sequencing data, revealed at least 33 TF genes differentially expressed in glucose or keratin. We also showed that StuA regulates the pH signaling transcription factor, PacC, a relevant TF recruited for keratin assimilation in T. rubrum. Furthermore, we demonstrated that StuA modulates positively pacC and influences alternative splicing events of pacC transcripts in keratin cultures. Our findings revealed that StuA represses pacC transcription in a co-culture with keratinocytes and modulates the expression of the pal pathway genes, besides suggesting that StuA is pivotal for pH recognition responses and nutrient assimilation in the host.

The clinical presentation, radiological characteristics, and outcomes of CPA in people living with HIV (PLHIV) remain poorly understood. We conducted a retrospective study at Hospital das Clínicas, University of São Paulo, Brazil, reviewing medical records of CPA patients from January 2010 to November 2024. HIV-infected and HIV-negative CPA patients were compared in terms of clinical features, diagnostic findings, treatment strategies, and outcomes. CPA diagnosis was based on European Society for Clinical Microbiology and Infectious Diseases and European Respiratory Society criteria. A total of 96 CPA patients were included, of whom 8 (8%) were PLHIV. Compared to HIV-negative patients, PLHIV were younger (median age: 44 vs. 52 years, p = 0.13) and more likely to have active pulmonary TB (38% vs. 4.5%, p = 0.013). Itraconazole was the most used antifungal in both groups (57% vs. 79%, p = 0.2). One-year mortality also did not differ significantly between PLHIV and HIV-negative patients (13% vs. 4%, p = 0.3). Notably, 50% of PLHIV experienced clinical failure despite prolonged antifungal therapy and/or surgery. In conclusion, CPA in PLHIV is frequently associated with active TB and presents with a high rate of clinical failure despite treatment. Our findings highlight the need for optimized diagnostic and therapeutic strategies for CPA in this under-recognized population. Further prospective studies are warranted to better define prognostic factors and improve management approaches.</p>","PeriodicalId":19017,"journal":{"name":"Mycopathologia","volume":"190 4","pages":"54"},"PeriodicalIF":3.6,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144285531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
