Apoptosis is a programmed cell death process that occurs naturally in multicellular organisms. It plays a crucial role in maintaining tissue homeostasis and removing damaged or unnecessary cells. Apoptosis is characterized by cellular shrinkage, DNA fragmentation, and controlled elimination without causing inflammation or harm to neighboring cells. The MCQ on […]

Extrinsic Pathway of Apoptosis (Apoptosis Molecular Mechanism Part 2)
Extrinsic Pathway of Apoptosis (The Receptor-Mediated Programmed Cell Death Pathway) In the extrinsic pathway of apoptosis, the death-inducing signal for the programmed cell death is triggered by an external stimulus. For receiving such an external death-inducing signal, the cell possesses plasma membrane receptors specific to each stimulus and thus the […]

Intrinsic Pathway of Apoptosis (Apoptosis Molecular Mechanism Part 1)
Two Types of Apoptosis In the previous post, we have discussed the characteristic features and significance of programmed cell death or apoptosis. As we discussed, the stimuli for the execution of programmed cell death can be of internal or external to the apoptotic cell. Based on the source of stimuli, […]
