Cobalamin (vitamin B12) positively regulates interleukin-6 levels in rat cerebrospinal fluid

Methylcobalamin (Also known as Mecobalamin, MeCbl, MetCbl, MetB12, MeB12, or Methyl B12) Methylcobalamin as an endogenous coenzyme plays as important a role in transmethylation of methionine synthetase in the synthesis of methionine from homocysteine
