Why do TAM receptors protect against neuroinvasive viruses despite their known immunosuppressive role?

The finding that Mertk/Axl deficiency increases viral susceptibility contradicts the established paradigm that TAM receptors dampen antiviral immunity. This unexpected protective role challenges current understanding of TAM receptor function in neuroinvasive infections. Gap type: contradiction Source paper: The TAM receptor Mertk protects against neuroinvasive viral infection by maintaining blood-brain barrier integrity. (2015, Nature medicine, PMID:26523970)
