ABSTRACT

We demonstrate here that the genetic incorporation of the fusogenic peptide HA2 into a CXCR4-targeted protein nanoparticle dramatically reduces the specificity of the interaction between nanoparticles and cell receptors, a factor to be considered when designing tumor-homing drug vehicles displaying endosomal-escape agents. The loss of specificity is concomitant with enhanced cell penetrability.

ABSTRACT

El 80 por ciento de los recién nacidos presentan grados variables de ictericia durante los primeros 7 días de vida, en la mayoría de ellos desaparecerá sin dejar ninguna consecuencia, sin embargo, aquellos neonatos que desarrollen hiperbilirrubinemia grave tienen el riesgo de presentar secuelas neurológicas. Este artículo analiza las manifestaciones clínicas de la encefalopatía bilirrubínica, su fisiopatología y las recomendaciones actuales de prevención y tratamiento además de la neuropatología del kernícterus.
