DUALITY OF
IMMUNE SYSTEM
Evidences
from an exhaustive survey of literature has revealed that during the early
stages pertaining to the historical development of immunological
experimentation, the, biologists duly learned that ‘certain specific types of immunity’ may be meticulously
transferred between animals (belonging to the same species) by actually transferring serum from immunized to
nonimmunized animals. Importantly, other kinds of immunity could not be
transferred effectively via blood
serum. Obviously, at a much later stage it was duly understood that these
special types of immunity may be easily and conveniently transferable only when
certain specific lymphocytes were transferred actually.
Based on
the further extensive and intensive researches carried out by the ‘immunologists’ across the globe
ultimately accumulated copious volumes of valuable informations and results
that are now well-known to reflect the two
major segments of the so called vertebrate
immune system, namely :
(a) immunity
associated with serum-transfer
reflecting the activities of the humoral
(anti-body-mediated) immune system*, and
(b) immunity
associated with transfer of lymphocytes
reflecting the activities of the cell-mediated
immune system*.
Nevertheless,
these two aforesaid major segments
exert their actions both individually, and together in order to safeguard the
humans from ailment irrespective of their age, race, and gender.
