The role of endoplasmic reticulum aminopeptidase 2 in modulating immune detection of choriocarcinoma.

Gestational choriocarcinomas are derived from placental trophoblast cells, with HLA-C being the only class I polymorphic molecule expressed. However, choriocarcinomas have not been profiled for endoplasmic reticulum aminopeptidase 2 (ERAP2) expression. ERAP2 trims peptides presented by human leukocyte antigens (HLA) that have shown to modulate immune response.

Molecular Signals Involved in Human B Cell Migration into the Retina: In Vitro Investigation of ICAM-1, VCAM-1, and CXCL13.

Purpose: B cells participate in diverse retinal immunopathologies. Endothelial adhesion molecules and chemokines direct leukocyte trafficking. We examined the involvement of three molecular signals in retinal transendothelial migration of human B cells: ICAM-1, VCAM-1, and CXCL13.
