Cerca de 20% dos indivíduos infectados com o HIV tem alguma queixa relacionada ao aparelho genital. A etiologia da doença ulcerosa em região anogenital nesta população é variada e são descritos na literatura agentes etiológicos diversos. Não existem dados sobre a etiologia das úlceras anogenitais em indivíduos infectados com o HIV no estado de Pernambuco. Os objetivos deste estudo são: analisar as úlceras anogenitais em pacientes infectados com o HIV nos seus aspectos clínicos e histopatológicos procurando estabelecer a etiologia desta afecção; além de descrever as características epidemiológicas desta população, como dados sociodemográficos e comportamentais. Trata-se de um estudo descritivo do tipo série de casos onde pacientes infectados com o HIV e história de lesões ulceradas em região anogenital internados em enfermarias ou atendidos em ambulatório do Hospital das Clínicas da Universidade Federal de Pernambuco no período de julho a dezembro de 2009 constituíram a casuística do estudo. A amostra foi do tipo conveniência, segundo a demanda do hospital. Foram examinados 15 indivíduos, sendo 12 homens e três mulheres. Sessenta por cento dos indivíduos referia ter parceiro único no momento do estudo e 40% afirmavam ser heterossexuais. Apesar de HIV positivos e de terem lesão ulcerada em região genital, cerca de 70% dos indivíduos referia nunca usar preservativos ou o faziam de maneira eventual. Todos negaram o uso de droga injetável e 60% negava história prévia de outra doença sexualmente transmissível. Foram examinadas 30 lesões ulceradas em região anogenital, numa média de duas lesões por paciente. As úlceras foram biopsiadas e foi realizado exame histopatológico. A maioria (70%) delas estava localizada em região perianal e 80% tinham mais de 10 dias de evolução. Em 13 biópsias evidenciaram-se alterações patognomônicas da infecção pelo herpes vírus. Em dois pacientes tanto o exame histopatológico, como o teste de Tzanck foram inespecíficos, porém um deles obteve melhora com o tratamento com aciclovir oral e o outro com creme de Imiquimod. Não foi observada relação entre a gravidade ou duração das lesões e a contagem de células CD4 e o uso de terapia antirretroviral altamente ativa. A abordagem correta desta afecção tem impacto na transmissão do HIV. A possibilidade de etiologia herpética deve ser aventada, embora a história e o exame clínico possam não sugerir alterações clássicas desta infecção

Discovery, characterization, and ligand specificity engineering of a novel bacterial transcription factor inducible by progesterone

Baer, R. Cooper 29 May 2020 (has links)
Having evolved longer than any other group of organisms, bacteria have been perfecting mechanisms of sensing their environments for billions of years. Recent advances in the field of biosensing have enabled miniaturization of existing biosensors, but the number of characterized biosensor elements remains limited. Sensing parts derived from bacteria make promising targets for integration into biosensor devices and could expand the repertoire of easily detectable compounds. Here, RNA sequencing screening was used to identify a novel TetR family 3-ketosteroid inducible transcription factor called SRTF1 (Steroid Responsive Transcription Factor 1) from the Gram-positive soil bacterium Pimelobacter simplex. This is the first transcription factor confirmed to be inducible by these steroids in-vitro. A potential regulon was identified using in-vitro chromatin immunoprecipitation sequencing, revealing a conserved 20 base pair long palindrome within several promoters in a region of the P. simplex genome highly differentially expressed on exposure to steroids. Biolayer interferometry and intrinsic tryptophan fluorescence were used to quantitatively characterize the transcription factor’s DNA binding strength and hormone induction specificity. Circular dichroism study of SRTF1 revealed it is primarily alpha-helical like almost all other TetR family transcription factors. Bases in a core GCCG repeat within the palindrome were identified as important for SRTF1 binding and a disrupted palindrome was generated that greatly increased a quantum-dot based SRTF1 biosensor’s sensitivity for progesterone. As the transcription factor displays cross reactivity to cortisol and aldosterone that is undesirable in a diagnostic device, a fluorescent reporter assay based on the transcription factor was constructed. This reporter assay showed a similar steroid induction profiles as purified SRTF1, and was used to select for mutant SRTF1 variants generated using error-prone polymerase chain reaction with reduced inducibility by these 11-hydroxy steroids. This pipeline for identifying novel transcription factors, characterizing their DNA and ligand binding profiles, and altering them through mutation of DNA and protein sequences could allow for an expanded number of biosensor parts.
