TLR4 and infection: In crustaceans, the components serving as receptors, such as Toll, C-type lectin (CTL), scavenger receptor (SR), β-integrin, polymeric immunoglobulin receptor (pIgR), laminin receptor, globular C1q receptor (gC1qR), lipopolysaccharide (LPS)-and β-1,3-glucan-binding protein (LGBP), chitin-binding protein (CBP), Ras-associated binding (Rab), and Down syndrome cell adhesion molecule (Dscam), have been reported to be related to the interaction with WSSV during the infection.
