Forssman antigen

https://doi.org/10.1351/goldbook.13158
Glycolipid heterophile antigen (globopentosylceramide) expressed on cell surfaces during embryonic and adult life in rodents and other mammals, and found in many pathogens, but probably not in humans.
Notes:
  1. Anti-Forssman antibodies directed against the terminal sugar moiety are commonly found in plasma and may be involved in Guillain–Barré syndrome (GBS).
  2. Anti-Forssman antibodies reportedly disrupt tight junction formation, apical-basal polarization, and cell adhesion.
