  1. 1. Thiol redox state in apoptosis : physiological and toxicant modulation

    Författare :Stefan Nobel; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Apoptosis is a physiological type of cell death used to regulate the number of cells during development and in adult organs. However, apoptosis can also be inappropriately activated or inhibited under pathological conditions. One of the critical mechanisms of apoptosis is the activity of cysteine proteases belonging to the caspase family. LÄS MER
