B cells along with their close
relatives the T-cells are a very
important part of your immune system.
B cells are a type of white blood cell
that help the body fight infection.
We call them B cells because they're
created in your bone marrow.
When B cells encounter a foreign agent in your body
they spring into action producing
molecules called antibodies that attack
and destroy the invader.
This process guards your body against infection.
In lupus this process goes haywire, causing
the immune system to make way too many antibodies.
These antibodies can then
attack healthy tissue and organs
resulting in the variety of negative
symptoms caused by lupus.
