The pineal gland, which is the gland that translates darkness into an endocrine signal by releasing melatonin at night, is now considered a key player in the mounting of an innate immune response. Tumor necrosis factor (TNF), the first pro-inflammatory cytokine to be released by an inflammatory response, suppresses the translation of the key enzyme of melatonin synthesis (arylalkylamine-N-acetyltransferase-alkyl-N-acetyltransferase, Aa-nat). Here we show that TNF receptors of the subtype 1 (TNF-R1) ...
