Programmed responses to external stimuli and stress allow cells to adapt to changing environmental conditions, and are critical for cellular survival. mRNA transcription by RNA polymerase II (Pol II) ...

Researchers at the University of Michigan used mice to show that dysfunctional mitochondria trigger a response that affects ...

The relationship between autophagy and cell death is complex because autophagy constitutes an adaptive response to different kinds of stress by which the cells avoid cell death; yet, in some ...

Stress granules are transient structures that assemble in response to cellular stress, temporarily halting nonessential processes to aid cell recovery. Under normal conditions, they protect the cell ...

Regardless of the cell type, the researchers found that damage to the mitochondria did not cause cell death. This observation ...

Type 2 diabetes is a condition where the body cannot produce enough insulin or does not use insulin effectively. Insulin is a ...

Find out why stress can worsen allergy symptoms. Learn about the cellular chain reaction that occurs in the body and how it ...

Evolutionary biologists have long hypothesized that the short-term physiological responses to stress help animals survive in ...

NEW YORK — Scientists have discovered that stressed-out immune cells in the brain produce toxic fats that contribute to Alzheimer’s disease. The good news is blocking this stress response ...

The study, published in the journal Neuron, highlights microglia, the brain's primary immune cells, as central players in both the protective and harmful responses associated with the disease.
