Anti-apoptotic BCL-2 proteins enable cell survival by preventing mitochondrial BAX/BAK-pore formation and by preventing pro-apoptotic Ca2+-release from the endoplasmic reticulum (ER) (Vogler M et al, Signal Transduct Target Ther, 2025). Hematological cancers are addicted to BCL-2 for their survival by counteracting pro-apoptotic oncogenic signaling. Hence, BCL-2 inhibitors emerged as novel precision medicines of which venetoclax is now FDA-approved for treating CLL patients. At the ER, BCL-2 proteins interact with IP3 receptor (IP3R), where they directly inhibit their Ca2+-flux properties (Cauwelier C et al, BBA-Mol Cell Res, 2024). As IP3Rs also reside at ER-mitochondrial contact sites (ERMCS), BCL-2-mediated inhibition of IP3Rs also prevents pro-apoptotic mitochondrial Ca2+ overload (Loncke J et al, BBA-Mol Cell Res, 2025). BCL-2 is thus a well-known anti-apoptotic protein, and most research has focused on this aspect of BCL-2. However, what the role of BCL-2 is in post-mitotic cells like neurons has been chronically understudied and is not well known. In this project, the Bultynck (Ca2+, IP3Rs, ERMCS, BCL-2 and autophagy expertise) and van Vliet (autophagy proteins, lipid signaling and membrane-contact sites expertise) labs with their highly complementary expertise’s will join forces to examine this important and overlooked aspect of BCL-2.
