Professor Janet Hapgood PhD (UCT)

Division or Group

Janet Hapgood

HOD Department of Molecular and Cell Biology, Faculty of Science, UCT; and Member, Institute of Infectious Disease and Molecular Medicine, Faculty of Health Sciences, UCT.

Janet Hapgood’s research group focuses broadly in intracellular molecular mechanisms of action of steroid receptors, in particular the glucocorticoid receptor (GR).  In particular, it is focussed on ligand-selectivity, regulation of gene expression as well as cross talk between steroid receptors and other signalling pathways, which allows functional integration between stress, reproduction and immune function. This research is conducted in the broad context of reproduction, inflammation, contraception and infectious disease, in particular HIV-1. Most recently her lab has focussed on investigating the mechanisms and effects on immune function and HIV-1 pathogenesis of different progestin contraceptives via the GR, as well as cross talk between the GR and other receptors, and the role of the unliganded GR.

 

KEY EXPERTISE: Intracellular molecular mechanisms of action of steroid receptors; the glucocorticoid receptor, in the broad context of reproduction, inflammation, contraception and infectious disease, in particular HIV-1.
