Greater focus on exploring other receptors, viz., Kidney Injury Molecule-1/T cell immunoglobulin mucin domain 1 (KIM-1/TIM-1), tyrosine-protein kinase receptor UFO (AXL), lectins, Cathepsins, etc., will further help in exploring their importance, which might help in deciphering their important role in promoting viral infection of the human respiratory system and indicate their role as alternative receptors for future clinical intervention strategies. The gene discussed is AXL; the disease is viral infectious disease.
