Area of Science:

• Cellular Biology
• Molecular Mechanisms
• Biochemistry

Background:

• Programmed cell death, including apoptosis and necroptosis, is essential for metazoan homeostasis.
• Dysregulation of programmed cell death is implicated in diseases like cancer and autoimmune disorders.
• Novel forms of non-apoptotic programmed cell death are increasingly recognized for their physiological and pathological importance.

Purpose of the Study:
