Identification and functional analysis of a novel IFN-like protein (CgIFNLP) in Crassostrea gigas
Interferons (IFNs) belong to class II helical cytokines family with pleiotropic biological activities, which have been demonstrated to play crucial roles in innate and adaptive immunity in vertebrates. In the present study, a novel IFN-like protein (designed CgIFNLP) was identified from oyster Crass...

Interferons (IFNs) belong to class II helical cytokines family with pleiotropic biological activities, which have been demonstrated to play crucial roles in innate and adaptive immunity in vertebrates.

The mRNA transcripts of CgIFNLP was detected in all the tested tissues including gonad, adductor muscle, hemocytes, mantle, gills, and hepatopancreas, with the highest expression level in gills (39-fold, P < 0.05).
