Lipid droplets: A dynamic organelle through the growth phases of Malassezia spp

The genus Malassezia has been associated with human and animal skin microbiota, dermatological conditions, and even systemic infections. This yeast is lipid dependent, so the sources of lipids available in the medium are essential for its survival and the development of its cellular functions. Lipid...

This yeast is lipid dependent, so the sources of lipids available in the medium are essential for its survival and the development of its cellular functions. Lipid droplets (LDs) are structures responsible for storing neutral lipids and are involved with various biological roles in animals, fungi, plants, and bacteria, with a relevant role in lipid metabolic processes in cells.

Esta levadura es dependiente de lípidos, por lo que las fuentes de lípidos disponibles en el medio son esenciales para su supervivencia y el desarrollo de sus funciones celulares. Las gotas de lípidos (LDs) son estructuras encargadas de almacenar lípidos neutros y están involucradas con diversos roles biológicos en animales, hongos, plantas y bacterias, con un papel relevante en los procesos metabólicos de lípidos en las células. Estudiamos la dinámica (tamaño y número) de LD a través de las fases de crecimiento en cinco especies de Malassezia utilizando la técnica de co-tinción de microscopía de fluorescencia confocal de barrido láser. Pudimos mostrar diferencias significativas en los parámetros analizados entre las diferentes Malassezia spp.MicrobiólogoPregrado15 páginasapplication/pdfspaUniversidad de los AndesMicrobiologíaFacultad de CienciasDepartamento de Ciencias BiológicasLipid droplets: A dynamic organelle through the growth phases of Malassezia sppTrabajo de grado - Pregradoinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/acceptedVersionhttp://purl.org/coar/resource_type/c_7a1fTexthttp://purl.org/redcol/resource_type/TPMalasseziaCrecimientoMicroscopía de fluorescencia confocalMicrobiota cutáneaMicrobiología201328125Publication0000-0003-3057-1966virtual::6644-1https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000178225virtual::6644-17ec7a7b4-b510-4816-b236-023aaa0754f0virtual::6644-17ec7a7b4-b510-4816-b236-023aaa0754f0virtual::6644-1THUMBNAIL26265.pdf.jpg26265.pdf.jpgIM Thumbnailimage/jpeg25484https://repositorio.uniandes.edu.co/bitstreams/2ea0c1a5-b130-4702-8c5a-27546aad5c46/download7afe1ed6a343063684c47563aa8d870cMD53TEXT26265.pdf.txt26265.pdf.txtExtracted texttext/plain29844https://repositorio.uniandes.edu.co/bitstreams/dd114287-10b0-49a0-b76c-8b315c6577df/download136901957973356b9d9e1b5327b94870MD52ORIGINAL26265.pdfapplication/pdf481001https://repositorio.uniandes.edu.co/bitstreams/18c011b2-f863-46f8-9af1-b8a607b9d993/download36bdd29ed8206dbc2cd24e39557249a9MD511992/55014oai:repositorio.uniandes.edu.co:1992/550142024-03-13 13:14:13.581http://creativecommons.org/licenses/by-nc-sa/4.0/open.accesshttps://repositorio.uniandes.edu.coRepositorio institucional Sénecaadminrepositorio@uniandes.edu.co
