Gadolinium 26-28 immunoglobulin heavy constant alpha 1 Homo sapiens 20-24 31748116-1 2020 Galactose-deficient IgA1 (Gd-IgA1) plays a crucial role in the development of IgA nephropathy (IgAN). Gadolinium 26-28 immunoglobulin heavy constant alpha 1 Homo sapiens 29-33 31748116-2 2020 However, the pathogenic mechanisms driving Gd-IgA1 production have not been fully elucidated. Gadolinium 43-45 immunoglobulin heavy constant alpha 1 Homo sapiens 46-50 31748116-3 2020 Innate-immune activation via Toll-like receptor 9 (TLR9) is known to be involved in Gd-IgA1 production. Gadolinium 84-86 immunoglobulin heavy constant alpha 1 Homo sapiens 87-91 31748116-4 2020 A proliferation inducing ligand (APRIL) and IL-6 are also known to enhance Gd-IgA1 synthesis in IgAN. Gadolinium 75-77 immunoglobulin heavy constant alpha 1 Homo sapiens 78-82 31748116-9 2020 However, siRNA knock-down of APRIL completely suppressed overproduction of Gd-IgA1 induced by IL-6. Gadolinium 75-77 immunoglobulin heavy constant alpha 1 Homo sapiens 78-82 31748116-10 2020 Neutralization of IL-6 decreased CpG-oligonucleotide-induced overproduction of Gd-IgA1. Gadolinium 79-81 immunoglobulin heavy constant alpha 1 Homo sapiens 82-86 31748116-11 2020 Furthermore, APRIL and IL-6 pathways each independently mediated TLR9-induced overproduction of Gd-IgA1. Gadolinium 96-98 immunoglobulin heavy constant alpha 1 Homo sapiens 99-103 31748116-13 2020 Hence, APRIL and IL-6 synergistically, as well as independently, enhance synthesis of Gd-IgA1.
