They kill bacteria by interacting with their cell-wall peptidoglycan, rather than permeabilizing their membranes, and synergize with antibacterial peptides. Peptidoglycan recognition proteins ...

Tissue processing advance can label proteins at the level of individual cells across whole, intact rodent brains and other large samples just as fast and uniformly as in dissociated single cells.

A group of Penn scientists has developed a new method to remotely control engineered cells inside the human body using heat.

Imagine being at a big marquee event in an arena, like the Super Bowl, with the roar of the crowd, the smell of hot dogs, and ...

Other peripheral proteins are secreted by the cell and form an extracellular matrix that functions in cell recognition. How Diverse Are Cell Membranes? In contrast to prokaryotes, eukaryotic cells ...

Proteins, the pillars of cellular function, often assemble into "complexes" to fulfill their functions. A study by the ...

A new study shows how an anticancer drug triggers an “outside in” signal that gets it sucked into a cancer cell. The work, ...

Researchers found that bioengineered CAR-T cells when mixed with other immune cells can "donate" proteins, suggesting ...

which guides the cells to one specific protein on a tumor, akin to law enforcement using facial recognition to find a criminal. The FLC-causing fusion protein represents a dangerous fugitive in ...

A "pocket" on the protein cyclin B is responsible for ensuring that the steps of cell division take place in the correct ...

The formation of protein complexes is a delicate process, with some proteins finding their match at synthesis.

Indeed, we found that OME is highly selective and only occurs between cells that contain identical or nearly identical TraA proteins (Fig. 3). Therefore OME involves kin recognition that is governed ...
