ABSTRACT
We previously reported that expression of the receptor-type tyrosine kinase Axl, which regulates cell survival and activation, enhances both pseudotype and live Ebola virus (EBOV) infection. To clarify the mechanistic basis of this enhancement, we created a series of Axl mutants and identified amino acids/domains necessary for this function, by using a pseudotype virus carrying the EBOV glycoprotein (GP). Analyses of the Axl mutants showed the importance of extracellular and intracellular regions for Axl functions, including ligand binding and signal transduction, in EBOV GP-mediated infection. These data suggest that EBOV uses the hysiological functions of Axl to enter cells.
