Cells that are infected by a virus or carry a carcinogenic mutation, for example, produce proteins foreign to the body. Antigenic peptides resulting from the degradation of these exogenous proteins inside the cell are loaded by the peptide-loading complex onto so-called major histocompatibility complex molecules (MHC for short) and presented on the cell surface. There,...

Nanomachines drill through cell membranes
Researchers in the US and the UK have developed a completely new technique to open cell membranes using photosensitive molecular machines. The devices, which drill their way through cellular lipid bilayers when exposed to light, can also destroy cells within minutes by disrupting the cell membrane. They might be used to deliver therapeutic drug payloads...
