Fusion mechanism
A fusion mechanism is any mechanism by which cell fusion or virus cell fusion takes place, as well as the machinery that facilitates these processes.
What is cell fusion?[edit | edit source]
Cell fusion is the formation of a hybrid cell from two separate cells.
What are the types?[edit | edit source]
- There are three major actions taken in both virus cell fusion and cell - cell fusion: the dehydration of polar head groups, the promotion of a hemifusion stalk, and the opening and expansion of pores between fusing cells.
- Virus-cell fusions occur during infections of several viruses that are healthconcerns relevant today.
- Some of these include HIV, Ebola, and influenza. For example, HIV infects by fusing with the membranes of immune system cells.
- In order for HIV to fuse with a cell, it must be able to bind to the receptors CD4, CCR5, and CXCR4.
