lymphocytes
small leukocytes- help defend body
, 2 types: B cells, t cells
B lymphocytes
B Cells
makes antibodies and pour into bloodstream
2 types: plasma/ memory b cells
antibodies
y shaped proteins
y binds w outside of b celll
-other end of y binds to a MO and kills it
antibodies
are known collectively as immunoglobulins
T lymphocytes
T cells
intensify the response of other immune cells to bacterial invasion
-produce CYTOKINES- further stimulate immune response
cytokine
protein secreted by cells and affects behaviour of nearby cells
regulate behaviour of immune cells
complement system
series of protons circulating in blood:
-facilitate phagocytosis of bacteria
-kill bacteria directly - form pores in bacterial cell membrane
function of complement system
• Destruction of pathogens
• Opsonization of pathogens
• Recruitment of phagocytes
• Immune clearance
trans-endothelial migration
, leukocytes push their way between endothelial cells and enter connective tissue
migration
leukocytes travel through the bloodstream to fight an infection
body response to inflammation
focuses host defence components at the site of an infection to eliminate MOs and heal
damaged tissue
inflammatory biochemical mediators
Biologically active compounds secreted by cells-activate the body's inflammatory response
chemokines
subgroup of cytokines- cause additional immune cells to be attracted to site of
infection/injury
acute inflammation
short term- normal process- protects and heals body
-increased movement of plasma and leukocytes from blood into injured tissues
5 signs of acute inflammation
heat, redness, swelling, pain, loss of function
chronic inflammaation
long lived- out of control- continues for more than a few weeks
-can destroy healthy tissue and cause more damage than the original problem
why does chronic inflammation occur
body is unable to rid itself of invading organisms
chemical mediators
biologically active compounds- secreted by cells that activate body inflammatory response
systemic risk factors
conditions/diseases-increase individual's susceptibility to periodontal disease
by modifying/amplifying host response to periodontal pathogens
examples of systemic risk factors
• Tobacco use
