Autophagy Causes
The many reasons and causes due to which autophagy occurs are given below:
- Nutrient Deprivation: When the body lacks nutrients, like during fasting or calorie restriction, autophagy increases or intensifies.
- Energy Crisis: Low energy levels, such as during exercise or metabolic stress, can signal for autophagy to begin.
- Cellular Damage: If cells detect damage or dysfunction, autophagy helps clean up the mess.
- Hormonal Signaling: Hormones like insulin and glucagon can influence autophagy, regulating its activity.
- Genetic Factors: Certain genes play a role in controlling autophagy, affecting how readily it occurs.
- Environmental Stress: Exposure to toxins, radiation, or other stressors can trigger autophagy as a protective response.
- Aging: Autophagy tends to decline with age, leading to a buildup of cellular junk and contributing to age-related diseases.
- Medications and Compounds: Some drugs and natural compounds can either enhance or inhibit autophagy, depending on their effects on cellular signaling pathways.
Autophagy
Autophagy comes from Greek words “auto” (self) and “phagy” (eating), which means cells eating themselves. Autophagy is a process where cells get rid of damaged parts to stay healthy. The various types of autophagy include macroautophagy, microautophagy, and chaperone-mediated autophagy. In this article, we will cover in-depth about autophagy types, examples, and more.
