Apoptosis is programmed cell death, and abnormal apoptosis can lead to the development of diseases such as cancer, neurological disorders and autoimmune diseases[1]. Two main apoptosis pathways:
Intrinsic Pathway
The intrinsic pathway, also known as the Bcl-2 regulatory or mitochondrial pathway (Figure 1), is regulated by Bcl-2 family proteins, including pro-apoptotic proteins (Bid, Bax, Bak) and anti-apoptotic proteins (Bcl-2, Bcl-xL)[2].
Extrinsic Pathway
The extrinsic pathway, also known as the death receptor (DR) pathway (Figure 1), is activated by binding death ligands to death receptors on the plasma membrane, including FasL, TNF-α and TRAIL. DR, Fas-associating protein with a novel death domain (FADD) and associated apoptotic signaling molecule (caspase-8) form the death-inducing signaling complex, resulting in the activation of caspase cascades effectors (caspase-3, caspase-6 and caspase-7)[2].
