Review of constructing animal models of depression after myocardial infarction / 中国药理学通报

The incidence of depression after myocardial infarction (DAMI) is high, causing significant harm to the patients' physical and mental health, but the pathogenesis is unknown. Establishing animal models which simulate the pathogenesis of DAMI in humans is an effective way to explore the mechanism of the disease. In this paper, problems existing in the modeling process, such as animal selection, model selection, model preparation and behavioral evaluation, are summarized and considered in order to provide reference for DAMI model research.

Operational models of allosteric modulation of G protein-coupled receptors / 药学学报

Since the Monod-Wyman-Changeux (MWC) model was initially proposed to explain the allosteric interactions between proteins and their ligands 50 years ago, there have been various models and hypotheses such as the induced-fit model on the interaction. These theoretical developments have been used broadly in the study of allosteric modulations of enzymes and receptors. In 1980, Lefkowitz and coworkers proposed a ternary complex model (TCM) for the regulatory mechanism of G protein-coupled receptors (GPCRs) that laid the theoretical foundation in the study of allosteric sites and ligands of GPCRs, the largest family of known receptors. The findings on how ligands interact with receptors to cause a functional response have significantly impacted the drug discovery field and accelerated the identification of allosteric modulators.
