Martínez-López, N., Pereiro, P., Saco, A., Lama, R., Figueras, A., Novoa, B. (2024) Characterization of a fish-specific Immunoglobulin-like domain-containing protein (Igldcp) in zebrafish (Danio rerio) induced after nodavirus infection. Developmental and comparative immunology. 162:105285.
Abstract
One of the most highly induced genes in zebrafish (Danio rerio) larvae after infection with the nodavirus red-spotted grouper nervous necrosis virus (RGNNV) was a member of the immunoglobulin superfamily (IgSF), which has remained uncharacterized and erroneously annotated in zebrafish and other fish species, such as galectin 17 (lgals17). We characterized this gene and named it immunoglobulin (Ig)-like domain-containing protein (igldcp), a new member of the IgSF that does not possess orthologs in mammals. Igldcp expression is induced by viral infection and it belongs to the group of interferon-stimulated genes (ISGs). In vitro overexpression of igldcp decreased RGNNV replication, whereas in vivo knockdown of this gene had the opposite effect, resulting in increased larval mortality. RNA-Seq analyses of larvae overexpressing igldcp in the absence or presence of infection with RGNNV showed that the main processes affected by Igldcp could be directly involved in the regulation of various cellular processes associated with the modulation of the immune system.
