Autophagy News and Research

RSS

Autophagy is a normal process in which a cell destroys proteins and other substances in its cytoplasm (the fluid inside the cell membrane but outside the nucleus), which may lead to cell death. Autophagy may prevent normal cells from developing into cancer cells, but it may also protect cancer cells by destroying anticancer drugs or substances taken up by them.

Intact autophagic vacuoles found to be indispensable in mediating competitive elimination of cancer cells

Elimination of transformed cells that can initiate cancer is necessary to maintain tissue integrity. In a new study, scientists from Tokyo University of Science show how this mechanism is regulated by the cellular process "autophagy."

Exercise hormone irisin blocks Parkinson's-associated α-synuclein aggregation and related neuronal toxicity

A new paper discusses the hope held out by recent results on a compound called irisin, a short protein secreted by skeletal muscle that produces some exercise-related effects on the brain.

Defensosomes versus COVID-19

In a recent study published in the journal PLoS Biology, researchers investigated the role of angiotensin-converting enzyme 2 (ACE2)-containing defensive exosomes, or 'defensosomes' against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections.

Molecular explanation for the contribution of autophagy to BAT energy metabolism

Obesity is a growing global health problem and its prevalence has tripled since 1975. More than 650 million people are affected by this condition worldwide, and 28% of people in Spain over 18 years of age have this complex pathology. Obesity is linked to conditions such as type II diabetes, cardiovascular disease, osteoarthritis, and certain forms of cancer.

Membrane lipid stops stress reactions and inhibits cell death

Programmed cell death is an important tool that an organism uses to keep itself healthy. When a cell does not function as it should, various stress reactions are activated. The goal of these reactions is to restore the original cell function.
