Graft-versus-host disease (GVHD) is a major risk factor for prolonged humoral immunodeficiency and vaccine unresponsiveness after allogeneic hematopoietic stem cell transplantation (allo-HSCT). However, the underlying mechanisms for this immunodeficiency are poorly understood. In this article, we describe previously overlooked impacts

Review of O-Linked Glycoproteins

O-Linked glycoproteins are usually large proteins with a molecular mass of >200 kDa. Glycosylation generally occurs in high-density clusters and may represent as much as 50-80% of the overall mass.

Přehled glykoproteinů s vazbou O

O-vázané glykoproteiny jsou obvykle velké proteiny s molekulovou hmotností > 200 kDa. Glykosylace se obvykle vyskytuje ve shlucích s vysokou hustotou a může představovat až 50-80 % celkové hmotnosti.
