Research summary
The highly polymorphic MHC class I molecule HLA-C is expressed on fetal trophoblast cells. This is the dominant ligand for NK cells in blood but we have increasing evidence that a major function of the NK receptors that bind HLA-C (known as KIR) are pivotal in determining how far trophoblast invades into the uterus, and the extent of remodeling of the maternal spiral arteries, establishing blood flow to the placenta. Dr Sue Hiby’s work on the immunogenetics of this interaction shows that one particular maternal KIR and fetal HLA-C combination is associated with the major diseases of pregnancy – recurrent miscarriage, fetal growth restriction and pre-eclampsia. I work as a technician with Dr Hiby and Proffessor Moffett on these genetic studies.
