Immune
response of host leukocytes for bacterial antigens
Abstract:
The immune system has traditionally been divided into innate and
adaptive components. The innate immunity refers to the
primary immunity against diseases. The innate immune response
develops first and then activates the adaptive immune response.
The innate components recognize only some antigens. These
structures are referred to as pathogen-associated molecular
pattern (PAMP),
for
example: lipopolisaccharide -
LPS,
peptidoglycan -
PGN,
lipoteichoic acid -
LTA,
bacterial DNA.
Some
bacterial antigens show similarity with host structures. This
phenomenon is called molecular mimicry and it is one of the
important pathogenic factors of microorganisms.
