RESUMO

Cornelia de Lange syndrome (CdLS) is a rare syndromic genetic disorder characterized by multiple congenital anomalies with upper limb reduction defects, along with cardiac, gastrointestinal, and genitourinary defects. It is caused by genetic variations in the chromatin regulator genes, most commonly, the cohesin complex. Even though molecular genetic testing is highly recommended to confirm the diagnosis, high costs and unavailability in some settings are significant setbacks, and clinical criteria could be used. The typical craniofacial features include generalized hirsutism, synophrys, microbrachycephaly, highly arched eyebrows, and long eyelashes, along with height and weight below the 5th percentile. In this paper, we present a case of a 16-day-old male infant in whom a clinical diagnosis of classical CdLS was made.

RESUMO

Introducción: La infección por Zika virus (ZIKV) ha sido asociada a múltiples complicaciones y nuevas formas de transmisión. La descripción del genoma y la estructura cristalizada permiten desarrollar análisis moleculares, incluyendo las propiedades inmunológicas. Objetivos: En este trabajo, se analiza a la glicoproteína E de ZIKV, con el fin de determinar su utilidad en la creación de una vacuna proteica recombinante. Métodos: Se analizó la glicoproteína E, por medio del software DNASTAR, en base a su antigenicidad de epítopos de células B y MHC-II, estructura secundaria, hidrofilizada, flexibilidad y accesibilidad a solvente en el virión maduro e hidratado. Resultados: Se identificaron 14 sitios antigénicos para células B, de los cuales, 7 comparten su antigenicidad para MHC-II. Al tomar en cuenta los demás parámetros analizados, los sitios se reducen a 3, con longitudes de 13, 9 y 5 aminoácidos. Conclusiones: La glicoproteína E de ZIKV podría desencadenar una respuesta inmune T-dependiente, por tanto, ser útil para la creación de una vacuna proteica recombinante.


Introduction: Zika virus (ZIKV) infection have been associated with multiple complications and new ways of transmission. The description of the genome and the crystalized structure allow the performance of molecular analysis, including immunological properties. Objectives: In this paper, we analyze glycoprotein E from ZIKV to determine its utility in the development of a recombinant protein vaccine. Methods: The protein was analyzed with the software DNASTAR, through the following properties: B cells and MHC-II antigenicity, secondary structure, hydrophilicity, flexibility and solvent-accessibility in the mature and hydrated virion. Results: We identified 14 antigenic sites with B-cells antigenicity, 7 of which shared the antigenicity for MHC-II. Considering other parameters analyzed, sites were reduced to 3, with length of 13, 9 and 5 amino acids. Conclusions: Glycoprotein E, from ZIKV, could trigger a T-dependent immune response, and therefore, may be useful in the creation of a recombinant protein vaccine.
