A Cedars-Sinai study has identified a previously unknown role for astrocyte cells in how the brain responds to damage and ...

Calcium (Ca2+) drives many cellular functions, though the way it controls quality of proteins in the endoplasmic reticulum ...

Cells manage a wide range of functions in their tiny package — growing, moving, housekeeping, and so on — and most of those functions require energy. But how do cells get this energy in the first ...

Microtubules are dynamic, tubular polymers composed of αβ-tubulin dimers that form an essential framework within eukaryotic cells. They orchestrate a wide range of cellular functions including ...

Many biological processes are regulated by electricity—from nerve impulses to heartbeats to the movement of molecules in and ...

As people age, their immune system function declines. T cell populations become smaller and can't react to pathogens as ...

Unlike our organs, cell organelles such as mitochondria are not fixed in place, but when, where, how, and why organelles move ...

A quick revision guide covering key concepts, biomolecules, cell organelles, and essential NEET-style MCQs to boost exam preparation.

Gene regulation is the process by which cells control the expression of their genes, determining when, where, and to what extent each gene is expressed. It is a fundamental mechanism that allows cells ...

When we need to recharge, we might take a vacation or relax at the spa. But what if we could recharge at the cellular level, fighting against aging and disease with the microscopic building blocks ...

Researchers shifted the focus to the internal properties of the membrane itself, specifically its viscosity, highlighting its critical role in controlling deformation and dynamics during essential ...

A new study identifies molecular factors that promote small vessel disease—and an active drug that can restore impaired ...
