Fig. 1From: Systemic perturbations in amino acids/amino acid derivatives and tryptophan pathway metabolites associated with murine influenza A virus infectionHeat map showing the profiles of 33 biogenic amino acids/AADs of control and IAV-infected mice. Each colored cell represents metabolite changes between the control and infection groups. The heat map was assembled by cluster analysis, and therefore, similar levels of metabolite changes are positioned at a short distance from each other, whereas different levels of metabolite changes are positioned at a long distance from each other. n = 5Back to article page
