These include some obvious mechanical activities such as endocytosis, cell motility and membrane resealing, but also others, such as replication and transcription. Taking the motor proteins as an ...

Transport across membranes All cells are enclosed by a cell membrane, which is selectively permeable. Molecules can move into or out of cells by diffusion and active transport. Cells can gain or ...

The fatty membrane surrounding every living cell is a vibrant environment where countless biological processes take place.

The Brandeis Molecular and Cell Biology (MCB) Program offers a uniquely collaborative, nurturing, supportive and close-knit community conducting internationally recognized research at the frontiers of ...

This takes place when molecules diffuse across the cell membrane by travelling through specific transport proteins. It occurs down a concentration gradient - molecules move from an area of high to ...

and administrator in the university’s biology department. The cholesterol-lowering drugs quell inflammation and reverse endothelial tissue damage, hints that they might curb the body’s excessive ...

Breakthrough study in Nature Materials reveals DNA nanorafts reshape synthetic cells for controlled membrane dynamics and ...

Membrane-bound organelles were the textbook ... What I finally saw in those blobs opened my eyes to a whole new world of cell ...

Among other things, membrane proteins act as channels, transporters or molecular sensors for the exchange of substances and information between the cell and its environment, but they are also ...

In biology textbooks, the endoplasmic reticulum is often portrayed as a distinct, compact organelle near the nucleus, and is commonly known to be responsible for protein trafficking and secretion. In ...
