Q

Pathology of Lupus

A

susceptibility genes pt is triggered by an environmental factor (sunburn)
cell DNA becomes damaged and undergoes apoptosis and dies
the DNA from the nucleus is exposed and causes the susp. genes to attack forming nuclear antigens and unable to clear the dead cells out
Antibodies are formed for the nuclear antigens
The antigen-antibodies complex form and enter the bloodstream
they attach to the bloodstream and organs causing inflammation
Complement system with enzymes allowing for fluid to enter cells and continue cell deaths
