When dangerous toxins teach fundamental biology

"What our work shows is how a complex in the center of the cell, the ER-Golgi interaction region, controls plasma membrane cholesterol, which is essential for many cellular functions, if not essential for multicellular life," ...

Measuring the temperature inside cells

Organelles inside cells constantly serve specific functions in the same way that individual departments handle certain tasks in an organization. Cellular processes alter the amount of heat organelles generate, but it is not ...

New research on the emergence of the first complex cells challenges orthodoxy

In the beginning, there was boredom. Following the emergence of cellular life on earth, some 3.5 billion years ago, simple cells lacking a nucleus and other detailed internal structure dominated the planet. Matters would ...

A simpler way to differentiate B cells and T cells

Our immune system is essential for our survival, as our bodies are constantly being exposed to bacteria, viruses, parasites, and other pathogens. Without an immune system, we would quickly lose the war against these pathogens ...

Researchers discover new endoplasmic reticulum sorting mechanism in plants

Protein sorting in the secretory pathway is essential for cellular compartmentalization and homeostasis in eukaryotic cells. The endoplasmic reticulum (ER) is the biosynthetic and folding factory of secretory cargo proteins. ...

Researchers identify novel cellular process that helps us understand the mechanisms of aging-related diseases

The study of autophagy—the recycling and repair process within cells—has huge potential to aid in fighting the aging process, bacterial and viral infections and diseases including cancer, Alzheimer's and Parkinson's.

Paradigm change in cell biology? Protein transport does not appear to work as we thought

One third of the proteins essential for life processes are produced in the endoplasmic reticulum (ER) of the cell and distributed via membrane vesicles. Sorting of proteins at ER exit sites and transport to the Golgi apparatus ...

Intimate associations between SARS-CoV-2 and mitochondria suggest new angles of attack

As one wise pundit recently observed, "everybody is a virologist now." For the many people whose interest in biology formerly began and ended with "the mitochondria is the powerhouse of the cell," a second axiom can now be ...

The evolution of the synapse

Among the most easily recognizable features of any nervous system is the synapse. While the question of how synapses evolved has been a longstanding mystery, it can now largely be solved. In a nutshell, it appears that the ...

How cells decide the way they want to recycle their content

Autophagy is a housekeeping process through which cells remove dysfunctional contents to balance energy sources during times of stress. Now, researchers from Tokyo Medical and Dental University (TMDU) identified a novel molecular ...
