The multifaceted activity of insect caspases

Area of Science:

• Molecular Biology
• Insect Physiology
• Cellular Biology

Background:

• Caspases are primarily known as executioners of apoptosis (programmed cell death).
• Emerging research suggests caspases have diverse functions beyond cell death.
• Insect caspases are implicated in various physiological processes.

Purpose of the Study:

• To review the established and recent findings on the non-apoptotic roles of insect caspases.
• To highlight the significance of these proteases in insect physiology and survival.

Main Methods:

• Literature review of existing studies on insect caspases.
• Synthesis of data on caspase functions in development, autophagy, immunity, and self-renewal.

Main Results:

• Caspases play critical roles in developmentally regulated autophagy during insect metamorphosis.
• Insect caspases are involved in neuroblast self-renewal processes.
• These proteases are essential components of the insect immune response.

Conclusions:

• Insect caspases possess multifaceted roles extending beyond apoptosis.
• These non-apoptotic functions are vital for insect development, homeostasis, and survival.
• Further research into insect caspase activities can reveal new insights into physiological regulation.
