{Reference Type}: Journal Article {Title}: Haplosufficiency of MHCII in autoreactive germinal center B cells. {Author}: Fahlquist-Hagert C;Wittenborn TR;Ferapontov A;Jensen L;TerczyƄska-Dyla E;Degn SE; {Journal}: Eur J Immunol {Volume}: 54 {Issue}: 1 {Year}: 2024 Jan 24 {Factor}: 6.688 {DOI}: 10.1002/eji.202350422 {Abstract}: Utilizing an autoimmune bone marrow chimera model we determined that B cells depend critically on MHCII expression for participation in the germinal center, but cells displaying a 50% reduction in surface MHCII compete efficiently with their wild-type counterparts. This provides insights into the requirements for germinal center participation.
