Caspases are a family of proteolytic enzymes that play a central role in apoptosis, the regulated process of programmed cell death essential for development, homeostasis and the clearance of damaged ...

Photoreceptors are specialized cells in the eye that convert light energy into neural signals. Several diseases that cause irreversible vision loss, including age-related macular degeneration, ...

Cellular injury entails disruptions in a cell's structure or function triggered by factors such as physical trauma, chemical exposure, infectious agents, and oxidative stress. These alterations may ...

Cancer immunotherapies often rely on activating immune responses, yet many tumors remain resistant because their internal survival mechanisms are poorly understood.

Apoptosis, or programmed cell death, is a tightly regulated biological process necessary for normal tissue maintenance and development. However, aberrations in apoptotic signaling networks are ...

American researchers have observed the process of cell self-destruction, or apoptosis, gaining insights into its velocity—an ...

Spinal cord injury often triggers a cascade of secondary damage that severely limits functional recovery, largely driven by ...

Researchers found photoreceptor cells can recover from apoptosis if stress signals are removed. Functional mitochondria and mitophagy helped restore cell health, suggesting potential strategies to ...

Here’s what you’ll learn when you read this story: When cells are about to die, they send signals that trigger proteins which are supposed to destroy them, but it doesn’t always happen that way. Some ...
