Summary of Leptospiral Immunoglobulin-Like (Lig) Protein Drivers, Charateristics, Functions, and Impacts. Lig proteins are exported to the leptospiral surface as lipoproteins via the localization of lipoprotein (Lol) pathway. Expression is stimulated by temperature and osmolarity. Their immunoglobulin (Ig)-like domains are responsible for various functions including leptospiral adhesion, complement evasion and modulation of hemostasis. These functions contribute to leptospiral virulence and immune evasion. Lig protein epitopes have been found to contain immunoprotective vaccine and serodiagnostic determinants.
