Abstract
ESTRATEGIAS DE VACUNAS DEL VIH-1 CONVENCIONALES, BASADAS EN LA PARTE EXTERNA DE LA PROTEINA ENV GP160/120, NO HAN SIDO HASTA AHORA CAPACES DE INDUCIR UNA INMUNIDAD PROTECTORA. ADEMAS, ANTICUERPOS REALZADOS PUEDEN INFLUENCIAR NEGATIVAMENTE LA PROGRESION DE LA ENFERMEDAD. DEBIDO A LA APARICION TEMPRANA EN LA INFECCION Y SU NATURALEZA PARTICULAR, LA PROTEINA P55-GAG DEL NUCLEO DEL VIRUS PARECE SER UN CANDIDATO A VACUNA QUE PROMETE. LA EXPRESION P55-NUCLEO FUE ENSAYADA MEDIANTE UNA COMBINACION DE VACUNA Y VIRUS BACULO. EL VERTIDO DE LAS PARTICULAS DE NUCLEO 90-110 NM EN UN MEDIO DE CULTIVO FUE OBSERVADA EN AMBOS SISTEMAS DE EXPRESIONES Y PROBADOS MEDIANTE UN MICROSCOPIO DE ELECTRON DE SECCION ULTRADELGADA Y ANALISIS DE SEDIMENTACION. LA ADICION DE LA SECUENCIA CODIFICADA DE PROTEASA EN UN PROCESO EFICIENTE DE LA MOLECULA PRECURSORA P55ACULO . PROTEASA SIGNIFICANTE MEDIANTE EL PROCESO DEL PRECURSOR GAG EN EL SISTEMA-VACCINIA QUE SOLO ALCANZADA POR LA ADICION DE LA SECUENCIA CODIFICADA POL ENTERA. EN CONTRASTE CON OTROS RETROVIRUS (MMLV), PROTEASA VIH-1 MEDIATIZADA PROCESADA NO DEPENDE DE LA MIRISTILACION DE P55-GAG. UN PROCESO MEDIATIZADO DE PROTEASA NO COMPLETA EL PROCESO DE MADURACION DE LAS PARTICULAS DE PRECURSOR-P55, PERO EN CONTRASTE, INHIBE LA FORMACION DE PARTICULAS, OTRAS INVESTIGACIONES ENFOCADAS EN LA APLICACION DE PARTICULAS-P55-GAG PREMATURAS. PARA EXTENDER SU ESPECTRO INMUNOLOGICO, UNA SECUENCIA CONSENSUADA DEL MAYOR VIH EPITOPE V3 DE GP120 QUE NEUTRALIZA, DISEÑADO EN NUESTRO LABORATORIO, FUE INSERTADO EN DIFERENTES ZONAS DE LA MOLECULA PORTADORA P55. LA EXPRESION DE LAS PROTEINAS QUIMERICAS P55/V3 EN E. COLI Y EL SISTEMA DE EXPRESION VACCINIA FUE PROBADO POR EL ANALISIS WESTERN BLOT, UTILIZANDO (I) ANTICUERPOS MONOCLONALES DIRIGIDOS A P55 Y LA ZONA V3 INSERTADA Y (II) SERA PEPTIDO MONOESPECIFICO ANTI-V3. PARTICULAS HIBRIDAS P55/V3 SERAN PURIFICADAS DESDE CELULAS INFECTADAS DE BACULOVIRUS. LOS VIRUS DE VACCINIA P55/V3 RECOMBINANTES SON, EN ADICION A LA PRODUCCION DEANTIGENOS, UTILIZADOS DIRECTAMENTE COMO UNA VACUNA VIVA EN ANIMALES EXPERIMENTALES.
