Toll like receptors are low molecular weight proteins made by certain cells as a mechanism to communicate with other cells urface receptors that enable certain cells to "see" molecules that signify the presence of microorganisms or virus Prote None of the above b.

Surface receptors that enable certain cells to see molecule that signify the presence of microorganism or virus
Toll-like receptors (TLRs) are a class of proteins that play a key role in the innate immune system.
They are single, membrane-spanning, non-catalytic receptors usually expressed on sentinel cells such as macrophages and dendritic cells, that recognize structurally conserved molecules derived from microbes.
