Timelapse video showing 90 minutes of cellular activity compressed into 15 seconds. You're watching an Immunity Project human clinical trial where a type of biodegradable polymer that is used in many FDA approved products called a PLGA microsphere is being incubated with a type of bone marrow cell called a dendrocyte in a tissue culture. This process is called phagocytosis. It shows the dendrocytes consuming the microspheres containing the targeted epitope. An epitope is the part of an antigen (such as a T-cell) recognized by the immune system. An antigen is the part of the cell that binds to an antibody reacting to fight off an enemy in the immune system like a virus.

The vaccine prototype created by Immunity Project to fight HIV encourages this process to occur. Our hope is that this will protect the cells from the virus.
