Ficolin: Difference between revisions

Latest revision as of 11:00, 23 June 2024

Function

Ficolin (Fic) are defense proteins which belong to the innate immune system and recognize carbohydrate molecules^[1]. 3 ficolins were identified in humans L-Fic or ficolin-2, H-Fic or ficolin-3 and M-Fic or ficolin-1.

Fiicolin-1 or M-ficolin is a pattern recognition molecule of the complement system expressed in myeloid cells^[2].

Disease

Fn may play a role in inflammatory diseases, apoptosis, lupus, preeclampsia and IgA nephropathy^[3].
