dc.description.abstract | The interaction between Immunoglobulin G (IgG) and Mycobacterium tuberculosis is crucial for understanding and addressing tuberculosis, as antibodies play an important role in immunity against the pathogen and, consequently, in vaccine development. In this study, IgG recognising 11 peptides derived from proteins in the mycobacterial envelope were isolated and purified using affinity chromatography, with results confirmed by electrophoresis. IgG1 and IgG2 subtypes were the most prevalent, suggesting a protective pro-inflammatory immune response against the pathogen. | |

dc.description.tableofcontents | La interacción entre las Inmunoglobulinas G (IgG) y Mycobacterium tuberculosis es fundamental para comprender y abordar la tuberculosis y el desarrollo de una vacuna. En este estudio, se aislaron y purificaron IgG que reconocen 11 péptidos derivados de proteínas de la envoltura de la micobacteria, utilizando cromatografía de afinidad, confirmando los resultados por electroforesis. Los subtipos IgG1 e IgG2 fueron los más prevalentes, sugiriendo una respuesta inmune proinflamatoria protectora contra el patógeno. La interacción de las IgG con los antígenos micobacterianos se evaluó mediante ELISA y microscopía de fluorescencia, observándose que las IgG obtenidas, especialmente las que reconocen el péptido 40416, mostraron la mayor afinidad en diferentes concentraciones. | |
