Production of SARS-CoV-2 Virus-Like Particles in Insect Cells

SARS-COV-2 Virus; Immune Responses and The Immunopathogenesis

Abstract Background and Objectives Clinical features of SARS-COV-2 virus include fever, headache, cough, sore throat, and shortness of breath, and in severe forms it leads to disseminated intravascular coagulation, septic shock, and ultimately death. Excessive secretion of proinflammatory cytokines such as TNF-α, IL-6, and IL-1 leads to cytokine storms in this disease. The emergence of new va...

Avian lymphoid leukosis: Virus-like particles in kidney Cells

MERS-CoV virus-like particles produced in insect cells induce specific humoural and cellular imminity in rhesus macaques

Middle East respiratory syndrome coronavirus (MERS-CoV) causes severe respiratory disease in humans with a case fatality rate of over 39%, and poses a considerable threat to public health. A lack of approved vaccine or drugs currently constitutes a roadblock in controlling disease outbreak and spread. In this study, we generated MERS-CoV VLPs using the baculovirus expression system. Electron mi...

The ORF7b protein of severe acute respiratory syndrome coronavirus (SARS-CoV) is expressed in virus-infected cells and incorporated into SARS-CoV particles.

Coronavirus replication is facilitated by a number of highly conserved viral proteins. The viruses also encode accessory genes, which are virus group specific and believed to play roles in virus replication and pathogenesis in vivo. Of the eight putative accessory proteins encoded by the severe acute respiratory distress syndrome associated coronavirus (SARS-CoV), only two-open reading frame 3a...

Characterizing Enterovirus 71 and Coxsackievirus A16 virus-like particles production in insect cells.

Enterovirus 71 (EV71) and Coxsackievirus A16 (CVA16) are two viruses commonly responsible for hand, foot and mouth disease (HFMD) in children. The lack of prophylactic or therapeutic measures against HFMD is a major public health concern. Insect cell-based EV71 and CVA16 virus-like particles (VLPs) are promising vaccine candidates against HFMD and are currently under development. In this paper,...
