It is the most widely used "genetic background" for genetically modified mice for use as models of human disease. They are the most widely used and best-selling mouse strain due to the availability of congenic strains, easy breeding, and robustness. [1] The median lifespan of C57BL/6 mice is 27–29 months and the maximum lifespan is about 36 ...
Glycine is an important amino acid that is essential for adequate nervous system function aiding in cell communication throughout the body. When tetanus toxin enters the body it is taken up by cholinergic nerve endings traveling axonally into the brain and spinal cord, disrupting motor function in individuals.

The ubiquity of CYP genes in humans worldwide, including CYP2A6 and CYP2B6, which metabolize nicotine, as well as other drugs, might suggest an evolutionary history with humans and plant neurotoxins. [12] The mammalian body has also evolved to develop defenses against over toxicity, such as exogenous substance metabolism and vomiting reflexes. [17]
