HJ1 T cells from a double transgenic mouse model expressing group 1 CD1 (hCD1Tg/HJ1Tg) exhibited significant IFN-γ and IL13 secretion in vitro upon activation by CD1b presenting self-phospholipids, including PC and phosphatidylethanolamine (PE), which suggests a further role of phospholipid presentation in autoimmunity [53,54]. Here, CD1B is linked to Autoimmunity.
