• [1.18] 
  - In acute #Colitis, #Melatonin led to increased clinical, systemic and intestinal inflammatory parameters. - During remission, continued MLT administration delayed recovery, increased TNF, memory effector lymphocytes and diminished spleen regulatory cells. - MLT treatment reduced #Bacteroidetes and augmented Actinobacteria and #Verrucomicrobia phyla in mice feces. - Microbiota depletion resulted in a remarkable reversion of the #Colitis phenotype after MLT administration, including a counter-regulatory immune response, reduction in TNF and colon macrophages. - There was a decrease in Actinobacteria, #Firmicutes and, most strikingly, #Verrucomicrobia phylum in recovering mice.
