SEMA7A is a membrane-bound semaphorin that associates with cell surfaces via a glycosylphosphatidylinositol (GPI) linkage.
SEMA7A is also known as the John-Milton-Hagen (JMH) blood group antigen, an 80kD glycoprotein expressed on activated lymphocytes and erythrocytes.
Czopik et al.
(2006) found that T cells from immunized Sema7a -/- mice had increased proliferative responses to antigen that were not attributable to Sema7a deficiency on macrophages or dendritic cells.
Sema7a -/- mice were prone to die at the onset of experimental autoimmune encephalomyelitis (EAE) and had higher clinical EAE scores compared with wildtype littermates.
Delayed-type hypersensitivity responses were also enhanced in Sema7a -/- mice.
