GRFT, SP‐D, CV‐N and hMBL are all mannose‐binding lectins with diverse pharmacological activities: SP‐D inhibits cell proliferation, migration and invasion by suppression of epidermal growth factor signalling (Hasegawa et al., 2015); CV‐N is known to block entry of the human immunodeficiency virus (HIV) into human cells (Boyd et al., 1997); hMBL binds and neutralizes influenza A virus and reduces the virus’ infection of respiratory epithelial cells (Hartshorn et al., 1993; Reading et al., 1997). The gene discussed is SFTPD; the disease is infection.
