Toll like receptors, recognize bacterial products and stimulates immune response by:: (A) Perforin and granzyme mediated apoptosis, (B) FADD ligand apoptosis, (C) Transcription of nuclear factor mediated by NF-kB which recruits cytokines, (D) Cyclin
Answer is C. Toll-like receptors They are membrane proteins that recognize a variety of microbe-derived molecules and stimulate innate immune responses against the microbes. These derive there name due to homology to a Drosophila protein called 'Toll'. The Toll-like receptors are expressed on many immune cells of the body. Signaling by Toll-like receptors results in the activation of transcription factors, notably NF-kB and AP-1.
