Defensive cells such as T cells identify pathogens by binding:

Question

Quizplus · Accepted Answer

T cells, a type of defensive cell, identify pathogens by binding to molecules through their receptors. Among the options given, Toll-like receptors (TLRs) are known for their role in the innate immune system, recognizing structurally conserved molecules derived from microbes. While T cells primarily use T cell receptors (TCRs) for antigen recognition, the concept of T cells directly using TLRs is more nuanced and generally applies to the broader immune system's recognition mechanisms, including dendritic cells and macrophages, which can influence T cell responses. However, the direct association of TLRs with T cells in the context of this question might be misleading, as TLRs are primarily associated with innate immune cells.
