Autoimmune response.
Step-by-step explanation:
Autoimmunity is defined as a condition where the body loses its self tolerance and the immune system of our body, responds against self antigen.
This results in destruction and hindrance in normal functions of body system.
Goodpasture syndrome is also an autoimmune disease that effects the lungs and the kidneys.
In this condition the immune system releases antibodies that circulates in the blood and attacks the tissues of kidneys and lungs.
The diagnosis of Goodpasture syndrome involves the presence of immunoglobulin G in the basal membranes of lungs and kidneys.
The presence of immunoglobulin G along the basement membrane of lungs reflects an auto immune response.
