Abstract

Introduction: Human Norovirus (HuNoV), a food-borne virus is the leading cause for acute gastroenteritis. However, its inability to propagate in vitro
persists as major challenge in understanding HuNoV biology.
Objective: This study aims to determine an effective culture system for HuNoV.
Methods: The Caco-2 cells were cocultured with Raji B cells on alginate hydrogel beads. Scanning electron microscopy (SEM) was performed to confirm
the three-dimensional (3D) cells morphology. Western blot (WB) analysis was performed to detect protein markers expressed by Microfold (M) cells.
Results: Optimization of Caco-2 cells monoculture in the alginate hydrogel beads showed optimum number of cells of 1 × 106 cells/ml, indicated
by the intact structure of the beads. Result of SEM showed clear structure of monoculture in the alginate hydrogel beads indicated by the presence
of smooth and regular apical surface while the coculture showed reduced apical surface of M cells. The result of WB showed downregulation of
Ulex europaeus antibody expression.
Conclusion: It is evident that the expression of M cells grown in 3D alginate hydrogel beads was successful, indicated by the structural morphology
seen under SEM as well as expression of protein marker by M cells. This established in vitro system is highly potential for cultivation of HuNoV.
