In addition to ACE2, other membrane proteins may act as Spike receptors (or co-receptors) for SARS-CoV2 among which we only mention AXL [44], Neuropilin-1 [45], and CD147 [46] that are highly expressed on cancer cells and might explain the increased susceptibility of cancer patients to infection [47,48,49]. This evidence concerns the gene AXL and cancer.
