Final answer:
Macrophages use the Toll-Like Receptor (TLR) for cytokine secretion. the correct option is c. Toll-Like Receptor.
Step-by-step explanation:
Macrophages use the Toll-Like Receptor (TLR) for cytokine secretion:
The Toll-Like Receptor (TLR) is a type of pattern recognition receptor (PRR) found on the surface of macrophages. When a macrophage detects the presence of pathogen-associated molecular patterns (PAMPs) on the surface of a pathogen, it binds to the PAMP using the Toll-Like Receptor. This binding triggers the secretion of cytokines, which are signaling molecules that help coordinate the immune response.
Therefore, the correct answer is c. Toll-Like Receptor. Macrophages use Toll-Like Receptors (TLRs) for cytokine secretion as a response to pathogens. Scavenger and mannose receptors are also involved in pathogen recognition but are not primarily responsible for cytokine secretion.
