Role for histone deacetylases in glucocorticoid receptor mediated transpression of natural killer cell activity
by Bush, Kristin A., M.S., LOYOLA UNIVERSITY CHICAGO, 2011, 76 pages; 1505654

Abstract:

During periods of psychosocial distress glucocorticoids (GCs) are known to reduce the lytic activity of natural killer cells (NKCA). Glucocorticoid treatment also reduces acetylation of histone residues; however, the glucocorticoid receptor (GR) lacks deacetylase activity. GR is known to interact with histone deacetylases (HDACs) and with corepressors that mediate gene transrepression. In this investigation, GC induced histone deacetylation was demonstrated to be due to GR recruitment of HDAC1 and the corepressor complex SMRT. These data show that reduced acetylation of immune functional genes associated with NKCA is likely due to histone deacetylation by HDAC1 and transrepression of those genes by SMRT. .
