Abstract
Imunoglobulin G (IgG) najzastupljenija je izoforma imunoglobulina u krvotoku čovjeka. Nglikani vezani na IgG utječu na efektorske funkcije ovog antitijela i na taj način reguliraju imunološki odgovor. Kompozicija IgG glikoma značajno se mijenja u pubertetu, trudnoći i menopauzi kao direktna posljedica promjena u koncentraciji estrogena. Međutim, točni mehanizmi kojima estrogen dovodi do promjene glikozilacije IgG-a nisu poznati. Cjelogenomske studije povezanosti su otkrile kako je gen ABCF2 reguliran estrogenom uključen u glikozilaciju IgG-a. Kako bismo potvrdili ulogu gena ABCF2 u tom procesu, povećali smo njegovu ekspresiju u staničnoj liniji FreeStyle-293-F koja stabilno eksprimira fuzijski protein dCas9-VPR i luči molekule IgG u stanični medij. Povećana ekspresija gena ABCF2 nakon manipulacije stanica alatom CRISPR/dCas9-VPR rezultirala je povećanom razinom galaktoziliranih glikoformi IgG-a (G1 i G2) i istovremenim smanjenjem agalaktoziliranih glikoformi IgG-a (G0) što sugerira da ABCF2, gen reguliran estrogenom, najvjerojanije sudjeluje u regulaciji glikozilacije IgG-a.
Abstract (english)
Immunoglobulin G (IgG) is the most abundant immunoglobulin isoform in the human bloodstream. Different N-glycans attached to IgG directly influence this antibody's effector functions and regulate the immune response. IgG glycome composition is changed significantly during puberty, pregnancy, and menopause, as a direct consequence of the change in estrogen concentration. However, the exact mechanisms by which estrogen modulates IgG glycosylation are unknown. Genome-wide association studies have shown that the estrogen-regulated gene ABCF2 is associated with IgG glycosylation. To functionally validate the role of the ABCF2 gene in this process, I overexpressed it in the FreeStyle-293-F cell line that stably expresses the dCas9- VPR fusion protein and secretes IgG. Overexpression of the ABCF2 gene resulted in an increased level of galactosylated IgG glycoforms (G1 and G2) and a simultaneous decrease in agalactosylated glycoforms of IgG (G0), suggesting that estrogen-regulated gene ABCF2 has a role in the regulation of IgG glycosylation.
