Asthma is chronic inflammatory disease affecting 5% of world population. Characterized by eosinophilic type2 inflammation. FKBP51 immunophilin, important modular protein of glucocorticoid receptor (GR). We aimed to evaluate immunocytochemical localization of GR and FKBP51 in induced sputum cells by using immunocytochemical method and immunofluorescent ant-FKBP51 and anti –GR antibody and estimation of IgE and Type 2 inflammatory cytokine IL-5,IL-13 by ELISA technique.GR in the sputum show non-significant decrease of cytoplasmic distribution of the patient groups and highly significant increase in steroid treated patients and non-significant increase in nuclear distribution in non-steroid, FKBP51 nuclear localization show non-significant increase in steroid treated and more than control and non-steroid treated patient and non-significant decrease in cytoplasmic localization in asthmatic than control. IgE serum level was highly significant elevated in both asthmatic groups when compared to control (P<0.001), it was in ICS treated asthmatics 297.59± 33.89 IU/ml, in nonsteroid treated 278.23±84.9IU/ml and in control 36.25±7.45 IU/ml, IL-5 show highly significant increase (P<0.001) in both steroid treated and non-steroid asthmatics, but not in control subjects it was 21.82±7.4Pg/ml, 17.97±4.02Pg/ml and 11.08±0.55Pg/ ml, respectively, IL-13 show non-significant increase in asthmatic groups when compared to control, it was 32.58±1.8Pg/ml, 29.14±2.76Pg/ml and 15.8±1.15Pg/ml, respectively. It can be concluded that elevated FKBP51 localization in nucleus in steroid treated patients associated with asthma type 2 inflammation cytokine increase.
