extra Flashcards
the T cells needs to recognize not only antigens but other molecules
costimulators
when T helper cells are acrivated they secrete?
IL2, which stimulates the proliferation
what kills parasites?
eosinophils and IgE
Main antibody
Igm
Protien antigens induce what ig
g, a, e
affinity maturation
from T help cells, improves the qulity of the humoral response
What is the only mechanism that prevest an ifnfection form becoming established/
immunogloulins
IgG
coat microbes and target them for phagocytosis
What activates the complement system?
IgG and IgM
IgA
secreted from mucosal epithelia and neutralizes microbes on lumens of mucosal tissue
IgG
transported accros placenta
what dies in contraction?
lyphoctre clones
memory cells life?
years
CD4 helpher cells help
macrophages to eliminated microbes
neutralize the infetivety of microbes and promote elimination
antibodies
earlies phase of inflammatory process
neutrophils 12-15
what can contain defensins and cathelicinds?
azurophilic grandules
CD14 highly expressed on?
monocytes
cytokines activate macrophages to become efficient at killing microbes
classical activation
promote itssues remodeling and repair
alternative acitvation
macrophages can divide at infection site
neutrophils cannot
essential for mast cell development
CKit
mast cells wher with? Ig
E
eosinophil matruation
GM-CSF, IL3 and IL5
