Fig. 2From: K+-Cl− cotransporter 1 (KCC1): a housekeeping membrane protein that plays key supplemental roles in hematopoietic and cancer cellsRegulation of K+-Cl− cotransport in HbS cells. During occlusive crises, PGIF are produced from ischemic non-erythroid tissues and taken up by RTC where it could increase KCC1 expression and overcome the potential inhibitory effect of low pO2i on K+-Cl− cotransport.
