EFNA2 and infection: This included three receptor–RBP pairs for which mRNA levels were significantly associated with infection in the abovementioned analyses (Cedar–EFNB1, Lujo–NRP2 and LCMV–DAG1), versus four with no apparent association (HCV–SCARB1, Cedar–EFNA2, SFTSV–MYH9 and rabies–NCAM1; Fig. 5b).
