A previously unknown structure discovered in our cells could pave the way toward new treatments for various genetic disorders. The existence of the organelle—which has been dubbed the "hemifusome"—was ...

Scientists have discovered that the internal shape of tiny drug-delivery particles—called lipid nanoparticles—has a big ...

Biofilms are conglomerates of bacteria and other organisms, which are feared in medicine as well as other areas because they ...

One ring to bind them all. Using state-of-the-art cryo-electron microscopy, the research team was able to decipher the structure.To do this, the membrane proteins were shock-frozen in a solution ...

Understanding ion transport dynamics in reactive vesicles is pivotal for exploring biological and chemical processes and essential for designing synthetic cells. In this work, we investigate how ...

The stomata of plants are small pores surrounded by pairs of specialized cells, known as guard cells. They provide gaseous exchange across the impermeable cuticle of plant leaves, and balance the ...

The dDMPC-PqiC membrane structure was fit as a five-layer model, which, ... Isom GL, Coudray N, MacRae MR, McManus CT, Ekiert DC, and Bhabha G LetB structure reveals a tunnel for lipid transport ...

Xiao et al. have shown that amino acid permease RcAAP1 from Ricinus can specifically transfer L-valine-phenazine-1-carboxylic acid (L-Val-PCA) conjugate across the plasma membrane. The localization of ...

In some cases, cells exert force and actively facilitate the passage of certain substances across their membrane, either expelling them from the cell or allowing them to enter. The primary methods ...

It is made up of a lipid bilayer and other macromolecules, such as carbohydrates, glycoproteins, and membrane proteins, which provide structure and restrict molecule transport across the cell.

The cell membrane has numerous channels for the transport of various substances, including ions, between the cell and its environment. Ion transport determines the ion exchange rate (or the ...
