The Effect of Melatonin on CREB and NF-κB Levels on LPS

To mediate these responses, it is hypothesized that melatonin regulates NF-κB levels in the brain. For this project, suprachiasmatic nucleus (SCN) 2.2 cells were chosen. These ...

Toll-like receptor
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 in sentinel cells such as macrophages and dendritic cells, that recognize structurally conserved molecules derived from microbes. Once these microbes have breached physical barriers such as the skin or intestinal tract mucosa, they are recognized by TLRs, which activate immune cell responses. The TLRs include TLR1, TLR2, TLR3, TLR4, TLR5, TLR6, TLR7, TLR8, TLR9, TLR10, TLR11, TLR12, and TLR13, though the latter three are not found in humans.They received their name from their similarity to the protein coded by the toll gene identified in Drosophila in 1985 by Christiane Nüsslein-Volhard. The researchers were so surprised that they spontaneously shouted out in German, ""Das ist ja toll!"" which translates as ""That's great!""
