The exact cause of Precursor B acutelymphoblastic leukemia (BCP-ALL) is stillunknown, but there has been a linkbetween BCP-ALL and Infection.
Researchers think that immune cells areactivated and expand, interacting withprecursor B cell that promote leukemia(Bürgler & Nadal 2017).
With T-helper cells present in thebone marrow, their role in theimmune system, and how receptivethe are to BCPALL cells, they wouldbe great for leukemia-supportiveimmune cells.
The interaction still remains unclear.
