✅ Blocking NF-κB or TNF-α in Siglec–E–deficient models restores graft survival.

✅ In humans, higher expression of SIGLEC7/9 (homologs of Siglec-E) is linked to better allograft outcomes —highlighting their potential as biomarkers or therapeutic targets. 3/4

✅ Siglec-E suppresses dendritic cell activation, limiting NF-κB signaling and TNF-α production.

✅ Loss of Siglec-E accelerates rejection in murine heart, kidney, and skin transplants through heightened T cell–mediated immunity. 2/4
