Article Abstract:

The mechanism of antigen-presenting cells (APCs) of immune system triggering cell-killing response in extracellular pathogens is described. The discovery of Sec61 complex, a protein-translocation channel, during endoplasmic reticulum (ER)-phagosome fusion revealed a new cross-presentation pathway in immune system.
