which of the three groups of PRRs is a molecule that circulates in blood and lymph
a. secreted prr
b. phagocystosis prr
c. toll like receptors
secreted PRRs
- is a molecule that circulate in blood and lymph
- circulating proteins BINDS TO PAMPs on the surface of pathogens
- it triggers the complement cascade, leading to opsonization of pathogen and speedy phagocytosis
which of the three groups of PRRs can trigger the complement cascade
a. secreted prr
b. phagocystosis prr
c. toll like receptors
secreted PRRs
- is a molecule that circulate in blood and lymph
- circulating proteins BINDS TO PAMPs on the surface of pathogens
- it triggers the complement cascade, leading to opsonization of pathogen and speedy phagocytosis
which of the three groups of PRRs initiates signal leading release of effector molecules
a. secreted prr
b. phagocystosis prr
c. toll like receptors
Phagocytosis receptors
- is cell surface receptors that bind the pathogen
- initiiating a signal leading to the release of effectro molecules

a. monocyte
b. neutrophil
c. macrophages
d. leukocytes

a. secreted prr
b. phagocystosis prr
c. toll like receptors
toll like receptors
- it can recognize different types of PAMPs

Diapedesis
- cells are capable of moving
- squeezing through the wall of blood vessel
