Molecular switch regulates autophagy in plants

Autophagy, or "self-eating", is an essential cellular quality control mechanism that clears the cell of protein aggregates and damaged organelles. This mechanism is inactive under normal conditions and only triggered upon persistent cellular stress.

Study shows the modulatory effect of resistance training on the endoplasmic reticulum in older adults

Aging involves a balance between oxidants and antioxidants, low-grade inflammation and a protein response that occurs at the cellular level, which is responsible for many health disorders.

Researchers discover previously unknown mechanism for how 'starvation response' is triggered

Body cells burn off fat reserves when nutrient supply from food ceases. A team led by Professor Volker Haucke and Dr. Wonyul Jang from the Leibniz-Forschungsinstitut für Molekulare Pharmakologie (FMP) has now discovered a previously unknown mechanism for how this “starvation response” is triggered, and what can inhibit it.

Research sheds light on how the cell selects suitable protein fragments for robust T-cell response

As task forces of the adaptive immune system, T lymphocytes are responsible for attacking and killing infected or cancerous cells.

SARS-CoV-2 spike protein and messenger ribonucleic acid found to translocate into the nucleus

In a new study, researchers reported severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) spike (S) protein and S messenger ribonucleic acid (mRNA) nuclear co-translocation as a novel feature of SARS-CoV-2 pathogenesis.
