Structure-based vaccine design seeks to create surfaces on immunogens that will elicit protective antibody responses against the target pathogen. Defining the atomic-level details of key surfaces on antigens accessible on pathogens is a primary requirement for structure-based vaccine design.

Los vectores virales son virus modificados diseñados para introducir material genético en las células. Este proceso puede realizarse dentro de un organismo o en un cultivo celular. Los vectores virales tienen aplicaciones generalizadas en la …

Las vacunas de vectores virales utilizan una versión modificada de un virus como vector para entregar a una célula un ácido nucleico que codifica un antígeno de otro agente infeccioso. Las vacunas de vectores virales no causan infección ni con el virus utilizado como vector, ni con la fuente del antígeno.

Adenovirus vectors are the most commonly employed vector for cancer gene therapy. They are also used for gene therapy and as vaccines to express foreign antigens. Adenovirus vectors can be replication-defective; certain essential viral genes are deleted and replaced by a cassette that expresses a foreign therapeutic gene.

2021年2月15日 · Adenovirus was originally used as a vector for gene therapy. In recent years, with the development of the next-generation vectors with increased safety and high immunogenicity to transgene products, its utility as a vaccine vector has continued to increase. Adenovirus-based vaccines are currently be …

2018年11月5日 · Adenoviruses are excellent vectors for delivering genes or vaccine antigens to the target host tissues and are being tested in several vaccine and gene therapy studies.

Lo hacen usando el virus modificado (el vector) para entregar el código genético al antígeno (en caso de la COVID-19 las proteínas Spike encontradas en la superficie del virus) hacia las células humanas.

The primary plasmid with the delivered cargo (often a gene) is called the transfer plasmid while the other plasmids with packaging or replication components are called helper plasmids. Below, we’ll breakdown the vector components first by virus and …

vector de antígenos heterólogos. Se requiere un mayor número de estudios clínicos de fase II y III para demostrar que los vectores de Salmonella podrán formar parte del arsenal de vacunas para la protección de la población mundial contra el constante acecho de los agentes infecciosos emergentes y reemergentes del presente siglo.

SV40 large T antigen (Simian Vacuolating Virus 40 TAg) is a hexamer protein that is a dominant-acting oncoprotein derived from the polyomavirus SV40. TAg is capable of inducing malignant transformation of a variety of cell types.
