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?

Cell fusion is the formation of a hybrid cell from two separate cells.

What are the types?

• 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.
