Nakon 50 godina misterije, naučnici otkrili novu krvnu grupu
Još 1972. godine lekari su, analizirajući uzorak krvi jedne trudnice, naišli na neočekivano otkriće – njena crvena krvna zrnca nisu imala molekul na svojoj površini koji je tada bio prisutan kod svih poznatih krvnih grupa.
TL;DR
- A new human blood group system, MAL, has been identified.
- The discovery stems from a 1972 case where a pregnant woman lacked a specific molecule on her red blood cells.
- The MAL system is based on the AnWj antigen, found on a protein linked to myelin and lymphocytes.
- The absence of the AnWj antigen can be due to a genetic mutation or suppression by certain blood diseases.
- Identifying the cause of the AnWj antigen absence is important for patient care and diagnosis.
- Previous research had identified other rare blood groups, such as Er, in recent years.
