Kynurenine Pathway

The kynurenine (KYN) pathway is an alternate tryptophan (TRP) breakdown pathway that, under physiological conditions, metabolizes TRP (> 95%) into KYN and an array of downstream neuroactive metabolites (Michels et al., 2018). The TRP to KYN conversion process is enabled by two rate-limiting enzymes: tryptophan 2,3-dioxygenase (TDO) and ...

Bile Formation and Secretion

Anatomical Determinants of Bile Secretion. The hepatocyte is a highly polarized cell, whose apical excretory domain represents about 10% to 15% of the cell surface area (Fig. 1A).The remaining major portions of the cell membrane consist of the basal membrane that faces the blood sinusoids and contains many microvilli, and the smooth lateral membrane that lines the intercellular space (Fig. 1B).
