In continuation of my update on Tranylcypromine
  An antidepressant drug used since the 1960s may also hold promise for treating sickle cell disease,  according to a surprising new finding made in mice and human red blood  cells by a team from the University of Michigan Medical School.
  The discovery that tranylcypromine, or TCP, can essentially reverse the  effects of sickle cell disease was made by U-M scientists who have  spent more than three decades studying the basic biology of the  condition, with funding from the National Institutes of Health.
