Toll-like receptor associated with virus is 
Select and explain. 
A. TLR2, B. TLR3, C. TLR5, D. TLR7
B: TLR3
Answer: B: TLR3 
Explanation: Toll-like receptors * TLRs in humans recognize PAMPS (pathogen associated molecular pattern) and are usually expressed on APCs. * Interaction between TLRs on APCs and PAMPS on pathogens activation of APCs and presentation of pathogen-derived antigen to T-cells forms a link between the innate and adaptive immune systems. * Activation of TLRs phagocytosis of the pathogen followed by activation of a proinflammatory environment with secretion of cytokines and chemokines.
