Introducción
Acquired or Specific Immunity
It is produced when the defense mechanism
fails due to an innate response. This
immunity is mainly characterized by its
specificity and because it keeps memory
of the pathogens as well as the produced
substances, so that when they come
to attack again, the recognition and
fighting will be performed more quickly.
This involved the B lymphocytes, T
lymphocytes and memory cells.
Humoral Immunity. - It is mediated
by B lymphocytes and it is transferred
through blood cells, thymus, spleen, lymph
nodes, etc.
Types of Acquired Immunity
Active Immunity. - It is the kind of
immunity that occurs when there are
infectious diseases; Moreover, they can be
acquired through vaccination and their
protection can last a lifetime.
Passive immunity. - It is a specific
type of immunity that results when an
individual acquires protective antibodies
from another organism, such as newborns
who get large amounts of antibodies in
colostrum and milk provided by his/her
mother.
Another Division of the Immune
Response
Cellular Immunity. - It is mediated by T
lymphocytes and it is transferred through
the plasma or blood serum (Ac).
