Re: Osoby z tą grupą krwi starzeją się wolniej. Naukowcy potwierdzają

Prawdziwi naukowcy wiedzą od lat, że grupę krwi można zmienić
Modifying a human's blood group is a complex and delicate process that
involves genetic and biochemical approaches. Here are some potential
ways this could be done:
1. Enzyme Treatment (Biochemical Modification)
    Scientists have discovered enzymes that can remove specific antigens
(A or B) from red blood cells, converting them into type O blood.
    Example: Bacterial enzymes from Elizabethkingia meningoseptica and
Flavobacterium have been shown to strip A and B antigens, effectively
converting blood to type O.
    This method is still experimental and being tested for safety and
efficiency.
2. Gene Editing (CRISPR/Cas9)
    Since blood type is determined by the ABO gene, CRISPR could
theoretically be used to alter or silence this gene in stem cells that
produce red blood cells.
    In genetically modified embryos, this could result in a permanent
change, but ethical concerns make this highly controversial.
3. Bone Marrow Transplantation
    Since blood cells are produced in the bone marrow, a person who
receives a bone marrow transplant from a donor of a different blood type
may develop the donor’s blood type.
    Example: A patient with type A blood receiving bone marrow from an
O-type donor will eventually produce O-type blood.
4. Stem Cell Therapy
    In the future, induced pluripotent stem cells (iPSCs) could be used
to regenerate blood with a modified blood type.
    Scientists are exploring ways to grow universal donor (O-negative)
blood from genetically modified stem cells.
Challenges & Ethical Considerations
    Immune Reactions: The immune system might attack modified blood
cells.
    Ethical Issues: Gene editing in humans raises concerns about
unintended consequences.
    Regulatory Barriers: Such modifications would require extensive
testing before clinical use.
