RESUMO

INTRODUCTION: Antibodies mediate pathogen neutralization in addition to several cytotoxic Fc functions through engaging cellular receptors and recruiting effector cells. Fc effector functions have been well described in disease control and protection against infectious diseases including HIV, Ebola, malaria, influenza and tuberculosis, making them attractive targets for vaccine design. AREAS COVERED: We briefly summarize the role of Fc effector functions in disease control and protection in viral, bacterial and parasitic infectious diseases. We review Fc effector function in passive immunization and vaccination, and primarily focus on strategies to elicit and modulate these functions as part of a robust vaccine strategy. EXPERT OPINION: Despite their known correlation with vaccine efficacy for several diseases, only recently have seminal studies addressed how these Fc effector functions can be elicited and modulated in vaccination. However, gaps remain in assay standardization and the precise mechanisms of diverse functional assays. Furthermore, there are inherent difficulties in the translation of findings from animal models to humans, given the difference in sequence, expression and function of Fc receptors and Fc portions of antibodies. However, overall it is clear that vaccine development to elicit Fc effector function is an important goal for optimal prevention against infectious disease.

RESUMO

COVID-19 is the pandemic outbreak that is caused by SARS-CoV-2 virus from December, 2019. Human race do not know the curative measure of this devastating disease. In today's era of nanotechnology, it may use its knowledge to develop molecular vaccine to combat this disease. In this article we are intended to propose a hypothesis on the development of a vaccine that is molecular in nature to work against COVID-19. The nanoconjugate may comprise with the inorganic nanoparticle layered double hydroxide intercalated with shRNA-plasmid that have a sequence targeting towards the viral genome or viral mRNA. This nanoconjugate may be used as a nasal spray to deliver the shRNA-plasmid to the target site. The nanoconjugate will have several advantages such as they are biocompatible, they forms as stable knockdown to the target cells and they are stable in the nasal mucosa.
